If you work on cars at the highest level, you already know it: even pressure, a clean spray pattern and rock-solid chemical resistance aren't side details – they're the foundation of a perfect result. That's exactly where Solo comes in, with spraying gear that doesn't just work but keeps performing, year after year. From the keen enthusiast to the professional detailer, Solo is the brand for anyone who expects their tools to be as reliable as they are.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial-grade quality for detailing pros: \u003c\/strong\u003eSolo units are built for constant use.

Unlike the simple pump sprayers you find in the consumer aisle, Solo systems work with steady pressure build-up and controlled media flow. Day-to-day that means the cleaner lands on the surface exactly the way you want it – not too harsh, not patchy, but repeatable and safe. On pre-washes, bug removers or APC work that's the whole game: you lift dirt properly without stressing the paint or any sealant already on it. The materials are built through and through for chemical resistance, which makes Solo gear a real option when you're running strong cleaners. That's exactly why we reach for Solo at Detailing1 wherever reliability and control aren't a nice-to-have but a must.\u003c\/p\u003e\n\u003ch3\u003eWhere it earns its keep day-to-day: from pre-wash to the engine bay\u003c\/h3\u003e\n\u003cp\u003eThe daily grind is where you see why \u003cstrong\u003eSolo Kleinmotoren GmbH sprayers\u003c\/strong\u003e are so respected in the pro world. On the pre-wash, even wetting lets the surfactants do their best work and loosens dirt safely. On wheels you can dial in the spray angle to reach the tricky geometry without throwing off pointless overspray. In the engine bay you get controlled application that respects the electrics and still cleans properly. That versatility is what makes Solo a fixture in high-end detailing setups. Pair it with our strong pre-cleaners, APCs and specialised care products and you get a workflow that isn't just efficient but delivers measurably better results – repeatable, car after car.\u003c\/p\u003e\n\u003ch3\u003eLongevity, precision and where it pulls ahead in the high-end segment\u003c\/h3\u003e\n\u003cp\u003eWhat clearly sets \u003cstrong\u003eSolo Kleinmotoren GmbH\u003c\/strong\u003e apart from basic spraying solutions is the uncompromising focus on lifespan and precision. Where cheap units tend to lose pressure or chemically tire out after a handful of jobs, Solo stays solid – even under heavy use. For professional detailers that means you can plan ahead, keep your processes clean and lose less time to downtime. That's why at Detailing1 we don't file Solo under accessories but as an essential part of a high-end detailing setup. Once you've worked with a clean, even spray under steady pressure, you won't want to go back. Solo isn't a short-lived trend – it's a tool that slots quietly and reliably into your working day and keeps proving itself, year after year.\u003c\/p\u003e","products":[{"product_id":"solo-cleanline-vario-foam-304-fa-fb-2-liter-schaumsprueher","title":"solo CLEANLine \"VARIOfoam\" (304 FA \/ FB) — 2 Litre Foam Sprayer","description":"\u003ch2\u003eMore control, more dwell time, less stress: solo CLEANLine \"VARIOfoam\" (304 FA \/ FB) — 2 litre foam sprayer\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eIf you want to dial in your cleaning foam exactly, the solo CLEANLine VARIOfoam 304 FA\/FB gives you stepless foam-grade adjustment, 3 bar working pressure and a 2-litre tank for even coverage and long dwell time – matched to the pH range of your cleaner.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003esolo CLEANLine \"VARIOfoam\" (304 FA \/ FB) — 2 litre foam sprayer\u003c\/strong\u003e is exactly the tool you grab when \"a bit of foam\" isn't enough and you want dwell time, cling and dosing in your hands like a pro. This is no toy foamer – it's a 2-litre foam pressure sprayer \"Made in Germany\" with patented VARIOfoam tech, 3 bar working pressure and chemical-resistant seals, built for consistent foam output instead of mood-of-the-day foam. And it's not just about how the foam looks, but what it does day-to-day: foam that stays put on vertical panels keeps lifting dirt longer, cuts down on mechanical abrasion (and with it your risk of wash marring) and makes your pre-wash far more controllable.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStepless foam grade, no swapping parts.\u003c\/strong\u003e You set the foam grade right at the nozzle with a dial – dry\/firm through to wetter\/gel-like, even while you work.

That's not red tape, it's materials science: the right seal type stays fit longer when it works inside the chemistry window it was made for.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eSetting the foam grade: varioFOAM patented tech and flat-jet spray\u003c\/h3\u003e\n\u003cp\u003eThe heart of it is the \u003cstrong\u003evarioFOAM\u003c\/strong\u003e tech: a patented foam-adjustment unit right ahead of the nozzle that lets you fine-tune the foam grade steplessly – exactly where it counts, namely at the outlet. Instead of living with felt inserts, swapping nozzles or \"trial \u0026amp; error\", you turn the dial and see the structure change straight away: from dry and firm (maximum cling, maximum dwell time) to wetter and gel-like (more wetting, faster flow into edges, badges, gaps). It sounds like a gimmick, but day-to-day it's a real process lever: on smooth vertical panels you want the foam set so it doesn't run off straight away but clings for a long time – because that very dwell time does the chemical work and saves you mechanical friction. The maker calls this out as a clear plus: longer-clinging foam improves cleaning action, cuts mechanical cleaning work and can lower cleaner consumption.\u003c\/p\u003e\n\u003cp\u003eOn top of that, output runs through a special flat-jet nozzle: a flat jet spreads the foam more evenly across a surface than a \"spot\" spray pattern, and you get a clean, closed layer faster. That's the whole point with pre-wash and wheels: not \"lots of foam somewhere\", but \"even coverage everywhere\". And because you can adjust the foam grade while you work, you react straight to real life: in shade a product often foams differently than on warm paint; on matte plastics you sometimes want to work a bit wetter, on painted panels firmer; on bug-covered fronts it can be thicker, on big side panels more efficient. That's the difference between \"foam is fun\" and \"foam does the job\".\u003c\/p\u003e\n\u003cp\u003eIf you want to squeeze the most out of it, think of the foam sprayer as a dosing and contact-time tool: you build an even layer first, give it time to work, then rinse clean – instead of compensating right away with mitt and pressure. For us in detailing that's the elegant route: less risk, more repeatability, and in the end paint that looks less \"worked over\". And yes – it sounds obvious, but being able to steer the foam without taking anything apart is exactly what makes you actually do it – rather than getting fed up after the third re-rig and just carrying on \"somehow\".\u003c\/p\u003e\n\u003ch3\u003epH range 1–7 or 7–14: choosing FKM and EPDM seals right\u003c\/h3\u003e\n\u003cp\u003eThe first thing that decides between joy and frustration is this: \u003cstrong\u003epH range\u003c\/strong\u003e matches material. With the solo CLEANLine VARIOfoam you get two versions you pick by chemistry, not by gut feel: the 304 FA is built for acidic cleaners in the pH 1–7 range (FKM seal), the 304 FB for alkaline cleaners pH 7–14 (EPDM seal). That's exactly how it's listed in the technical data, including 3 bar spray pressure and 2 L fill volume.\u003c\/p\u003e\n\u003cp\u003eWhy it matters: a \"seal\" isn't sexy, but it's the part that decides whether a pressure sprayer runs butter-smooth after a few jobs or suddenly gets stiff, weeps or loses pressure. EPDM often goes where water, steam and lots of water-based chemicals are in play; FKM (often known as Viton®) tends to get picked for higher chemical load, temperature or certain media. Day-to-day that doesn't mean \"one is always better\", it means \"one is the right fit\". That's exactly why SOLO splits the versions by pH window: so your tool stays durable and tight inside its intended chemistry range.\u003c\/p\u003e\n\u003cp\u003eFor car detailing it translates simply: if you work a lot with acidic foams (say for mineral deposits or special jobs), grab the FA. If you mostly run alkaline foams\/degreasers (typical for greasy road film, workshop grime, heavy pre-cleaning), grab the FB. And if you're thinking \"I'll just take one and do everything\" – sure, plenty do, but that's exactly where the classic problems show up: foam goes inconsistent, seals age faster, and you've got a pro tool that suddenly feels like a throwaway sprayer. Pick to match, and the system stays stable: fast pressure build-up, repeatable foam picture, fewer surprises.\u003c\/p\u003e\n\u003cp\u003eExtra bonus: the 304 comes with 2 litres as the \"bigger\" generation and, per the product info, replaces the popular smaller 1-litre versions (303 FA\/FB). Meaning: you get the exact same thinking (pH window + foam control), just with more reach per fill – which simply makes sense for vehicle pre-wash and several cars a day.\u003c\/p\u003e\n\u003ch3\u003eVehicle pre-wash, wheel cleaning: results and best practice in detailing\u003c\/h3\u003e\n\u003cp\u003eIf you want to play the \u003cstrong\u003evehicle pre-wash\u003c\/strong\u003e part right, foam isn't a show effect but \"contact time on paint\" – and that's exactly what the solo CLEANLine VARIOfoam (304 FA\/FB) is built for: you lay down a homogeneous foam layer that clings longer on smooth, vertical panels and can therefore work longer. The maker describes it as a clear benefit: longer dwell time improves cleaning action, cuts mechanical cleaning work and can let you use more neutral chemistry; lower aerosol formation is also named as a plus. For us in car care the key point: the more dirt you dissolve chemically and with time, the less you have to \"push away\" later with the wash mitt – and that's exactly the lever against wash marks.\u003c\/p\u003e\n\u003cp\u003eWith wheels the principle is similar, but the surface is more complex: spokes, edges, bolt holes – everywhere the foam can be either too dry (sits nicely but wets poorly) or too wet (runs straight off). Here the varioFOAM adjustment is your trump card: you set it so the foam clings at critical spots but has enough \"wetness\" to creep into the geometry. And because you can re-tune while you work, you adapt: warm wheel vs cold wheel, polished face vs rough casting, light soiling vs baked-on film. You don't have to overdose just because your application is uneven – you make it even.\u003c\/p\u003e\n\u003cp\u003eAnother practical sweet spot: interior and textile surfaces, when you deliberately want to work with foam instead of \"wet soup\". The product info explicitly names moisture-sensitive surfaces like carpets and textile surfaces as a suitable application, because foam holds the moisture more on the surface and \"soaks through\" less. In detailing that's a classic pro move: controlled chemistry on the surface, then take it up\/extract cleanly, rather than flooding everything. Important: here too the setting decides – too dry can reduce wetting, too wet becomes \"water work\" again. Which is exactly why stepless re-tuning is worth so much.\u003c\/p\u003e\n\u003cp\u003eTo get genuinely premium results with the foam sprayer, think about three things – without checklist overload: first, your cleaner has to be foam-capable (sounds obvious, but it's the most common reason for disappointing \"foam\"). Second, even coverage matters more than maximum foam height: a calm, closed film works better than \"peaks and valleys\". Third: let time work for you. Foam is there to extend dwell time; if you panic-rinse after ten seconds, you throw away the whole advantage. And because at Detailing1 we don't just sell but love processes: combine the foamer smartly with your wash routine. After pre-wash you want a really good \u003ca href=\"\/en\/collections\/autoshampoo\"\u003ecar shampoo with high slickness\u003c\/a\u003e, because the remaining dirt then comes off the paint more easily and safely. When you dry after rinsing, a \u003ca href=\"\/en\/collections\/trockentuecher\"\u003ehigh-pile drying towel\u003c\/a\u003e makes the difference, because it soaks up water fast without \"pushing\". And on wheels a \u003ca href=\"\/en\/collections\/felgenreinigung\"\u003ematching wheel cleaner\u003c\/a\u003e plus brush is still the combo that turns \"clean\" into \"detailing-clean\" – with the foam application as your controlled starting point.\u003c\/p\u003e\n\u003cp\u003eBottom line, the solo CLEANLine VARIOfoam 304 isn't just \"a foam sprayer\", it's a tool that gives you process control: foam structure, dwell time and chemistry compatibility are definable instead of random. That's exactly what high-end detailing feels like: you decide the result – not the accessory.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"solo","offers":[{"title":"2 liters \/ Acid (pH 1-7) 304 FA","offer_id":56936685142351,"sku":"D1-SOL-30431","price":25.35,"currency_code":"EUR","in_stock":true},{"title":"2 liters \/ Alkaline (pH 7-14) 304 FB","offer_id":56936685175119,"sku":"D1-SOL-30432","price":25.35,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/solo-cleanline-vario-foam-304-fa-2-liter-schaumsprueher.png?v=1769813735"},{"product_id":"solo-cleanline-variofoam-333-fa-4-liter-schaumsprueher","title":"CLEANLine \"VARIOfoam\" (333 FA) 4-Litre Foam Sprayer with Coiled Hose","description":"\u003ch2\u003eMore cling, more control, less hassle: the solo CLEANLine \"VARIOfoam\" (333 FA) as a pro foam sprayer with coiled hose\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eThe solo CLEANLine „VARIOfoam“ (333 FA) is a 4-litre foam sprayer with 3 bar working pressure and an adjustable varioFOAM nozzle, letting you dial your cleaning foam from dry-and-clingy to gel-like-wet mid-spray – spot on for pre-wash and wheels.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003esolo CLEANLine \"VARIOfoam\" (333 FA) — foam sprayer with coiled hose\u003c\/strong\u003e is exactly the tool you want when you don’t just want “some foam” on the pre-wash, but a repeatable, clean layer of foam that actually stays put on vertical panels.

At its core it’s about contact time, wetting and controlled run-off: a clingy, drier foam stays longer on paint and plastic, so the surfactants have time to break down road film. A wetter, gel-like foam wets faster and flows more evenly into contours, badges and gaps – perfect when you want to cover ground quickly. This is exactly where \u003cstrong\u003evarioFOAM\u003c\/strong\u003e shows its strength: you turn the dial right on the nozzle and change “dryness” and density mid-spray, without stripping anything down. Day-to-day that’s not just handy, it gets you repeatable results, because you can trim your setup to the product, temperature and how dirty the car is.\u003c\/p\u003e\n\u003cp\u003eOn the technical side that’s genuinely nice for paint safety: when the pre-wash foam clings evenly, you cut the need for mechanical “emergency rubbing” in that first round – the exact moment when grit is still at its most aggressive. That lowers the risk of picking up fine wash marks on the mitt pass that follows, because you’ve already loosened and rinsed off more dirt beforehand. And because the 333 FA works at 3 bar, the foam comes off the nozzle consistently instead of collapsing after the first few bursts. The combo of a 4-litre tank, piston pump and the SOLO special flat-jet nozzle is made to deliver “surface” – bonnet, doors, rear in one clean flow.\u003c\/p\u003e\n\u003cp\u003eIf you run the 333 FA with us as a set with coiled-hose handling, the practical win is simple: less hose spaghetti round the wheels, less tugging on the unit and more control as you work your way round the car. And that control is the difference between “foam on somehow” and “foam on so it works for you.” Fitting with that, our tip from day-to-day: pair the foamer with a proper pre-wash setup, e.g. a matching \u003ca href=\"https:\/\/detailing1.de\/vorwaesche\/\"\u003epre-wash cleaner for road film\u003c\/a\u003e and – if you want it as safe as it gets – a \u003ca href=\"https:\/\/detailing1.de\/waschzubehoer\/\"\u003egentle wash mitt setup\u003c\/a\u003e for the contact wash after.\u003c\/p\u003e\n\u003ch3\u003eWheel cleaning, pH range and FKM seals – how to use the 333 FA cleanly and without harming materials\u003c\/h3\u003e\n\u003cp\u003eOn wheels especially, foam isn’t just show, it’s strategy: brake dust and film like to sit in edges, around wheel bolts and in the barrel. Work there with a well-set foam and the chemistry stays where the action is instead of running straight off. So first things first: \u003cstrong\u003eFKM seals\u003c\/strong\u003e are a real-world plus here, because they’re built for more demanding cleaners. SOLO describes it as suited to foaming, acidic cleaners in the pH 1–7 range; the product info also lists use with neutral, strongly acidic and mildly alkaline cleaners. For you that means you can use the 333 FA very broadly – but you should always dilute the chemistry to spec, not “freehand by feel,” and test on an inconspicuous spot if in doubt.\u003c\/p\u003e\n\u003cp\u003eHere’s what a clean day-to-day routine looks like, without getting lost in a thousand steps: mix your foaming cleaner in the tank, pump up pressure (by hand via the piston pump) and set varioFOAM to “wet” at first, so you get wetting everywhere fast. Then dial to “clingier” once the surface is wet – the foam grips better and dwell time goes up. That switch mid-spray is exactly where the 333 FA shows its pro character: you adjust the foam structure instead of constantly changing your product or your technique. And with a 1.4 m hose plus a 40 cm wand you reach the wheels and the edges of the arches.\u003c\/p\u003e\n\u003cp\u003eIf you’re working in a business (or just like being efficient), the optional compressed-air valve is interesting: it lets you build pressure without hand-pumping – handy for longer stints with a steady spray pattern. SOLO lists this accessory as a compressed-air connection valve with FKM seals and an integrated (automatic) pressure-relief valve. For us it’s the kind of upgrade you don’t “need” – but after the first long Saturday you suddenly can’t do without it.\u003c\/p\u003e\n\u003cp\u003eA fitting combo from our range: for wheels it makes sense to pair the foam with a targeted \u003ca href=\"https:\/\/detailing1.de\/felgenreinigung\/\"\u003ewheel cleaner setup\u003c\/a\u003e and not forget the drying after – a good \u003ca href=\"https:\/\/detailing1.de\/trockentuecher\/\"\u003edrying towel\u003c\/a\u003e stops water spots and gets the finish to “done” faster.\u003c\/p\u003e\n\u003ch3\u003eFoam cling on vertical panels – dwell time, results and the typical mistakes with a foam sprayer\u003c\/h3\u003e\n\u003cp\u003eThe reason we love foam in the first place: on smooth, vertical panels a well-set foam can cling longer and so dwell longer – and that’s exactly what improves the cleaning without you having to reach straight for the brush. The product info spells this out for car cleaning and other vertical, smooth surfaces: more cling means more time for the chemistry, less mechanical work and easier working on sensitive surfaces. That’s not “marketing haze,” it’s simply physics plus chemistry: the more even the foam layer, the more even the surfactant work.\u003c\/p\u003e\n\u003cp\u003eThe typical mistakes nearly always happen in two places: mix and setting. Mixed too thin and it’s “wet, runs straight off” – then you need more product or more mechanical help. Mixed too thick can look spectacular, but doesn’t necessarily clean better, because the wetting suffers and you end up fighting residue. So the varioFOAM setting is your fine-tuning tool: first make sure the surface wets cleanly, then go for more cling when you want contact time. And one more pro note from day-to-day: if the foam layer suddenly “flips” (goes watery all at once), it’s often not the unit but the pressure cushion.

That’s exactly where \u003cstrong\u003evarioFOAM\u003c\/strong\u003e plays its trump card: you don’t just set the foam roughly once, you fine-tune it as you go. The dial sits right in front of the nozzle so you can tweak the foam character in real time: drier and clingier when you want maximum grip on smooth, vertical panels (read: longer dwell time), or wetter\/gel-like when you need more flow to wet contours, swage lines, badges and awkward nooks evenly.\u003c\/p\u003e\n\u003cp\u003eIn car care that’s worth its weight in gold: on a pre-wash you typically want foam that doesn’t run straight off, so the dirt can loosen before you go in mechanically. That lowers the risk of dragging grit „dry“ across the paint – not because the foam works magic, but because you give it the time to break down the dirt layer. And on wheels? There you often want it a touch „wetter“, so the foam creeps into the spoke beds and wets the surface evenly, instead of just clinging decoratively as a cloud on the outside. That control is exactly the difference between „foam looks good“ and „foam works well“.\u003c\/p\u003e\n\u003cp\u003eWhat matters just as much is what you \u003cem\u003edon’t\u003c\/em\u003e have to do: no unscrewing the nozzle, no conversion, no fiddling. That’s not just convenient, it makes the process repeatable – you find your setting, remember it, and hit it again next time. And because the foam sits on the surface longer when set right, you typically cut down on aggressive scrubbing. The upshot is a workflow that feels more like a pro routine than trial and error.\u003c\/p\u003e\n\u003ch3\u003eVehicle pre-wash and wheel cleaning with 9 litre CLEANLine foamer, 3 bar and FKM seals\u003c\/h3\u003e\n\u003cp\u003eWhat counts day-to-day: how comfortably the unit works across a whole car – and how cleanly you get the chemistry where it needs to act. The 309 FA is built as a large foamer with an extremely tough, UV-resistant polyethylene tank and brings 9 litres of nominal volume. The wide filler opening lets you pour cleaner in easily; a fill-level mark helps you dose without playing „ballpark“. The large-volume pump is built to build a working pressure of 3 bar efficiently. In car care that means an even foam pattern and longer working stretches, without topping up the pressure every few minutes.\u003c\/p\u003e\n\u003cp\u003eThe spray lance on the 309 FA is a 50 cm plastic tube (non-corrosive) and the hose runs 1.4 m – sounds like „small numbers“, but it makes a big difference to handling: you work your way round the front, sills and rear in control, without forcing yourself into awkward angles all the time.\u003c\/p\u003e\n\u003cp\u003eOn chemical compatibility, without the marketing fog: the system suits foaming neutral and acidic cleaners and is described, among other things, for limescale residue\/urine stone, flash rust and laying down acidic cleaning foams; on top of that, suitability for car care, vehicle pre-wash and wheel cleaning is named explicitly. The technical heart of it is the chemical-resistant components – the FKM seals in particular – plus a nozzle setup built for foam delivery (a special flat-jet nozzle).\u003c\/p\u003e\n\u003cp\u003eWhat does that mean for you in the detailing day-to-day? You can build your pre-wash so the foam doesn’t just „sit on top“, but wets the surface evenly and clings. After that you carry on – depending on your setup with a pressure washer, rinseless pre-soak or hand wash. And when you tackle big surfaces (shop, fleet, campers, off-road rigs) you’ll love the optional accessory options: there’s a wheel set with a handle so you can roll it instead of lugging it, and a compressed-air valve to build the pressure externally – both are provided as optional accessories. Translation: less hauling, more rhythm in the workflow.\u003c\/p\u003e\n\u003ch3\u003eCleaning foam on vertical surfaces: dwell time, cleaning power and typical use cases\u003c\/h3\u003e\n\u003cp\u003eA good foamer is at heart a „time manager“ for chemistry. The decisive lever is dwell time: on smooth, vertical surfaces a foam that’s too wet runs straight off – the active ingredients are gone before they work. An optimally set, clingy foam holds on longer, can dwell longer and so improves cleaning power. The product description addresses exactly this benefit: longer cling, better performance and less mechanical cleaning work.\u003c\/p\u003e\n\u003cp\u003eTypical use cases aren’t just paint and wheels, but anything that benefits from controlled, clinging foam: sill areas, door entries, door shuts (dosed carefully), plastic add-on parts – and textile surfaces and carpets are named as suitable too. Which brings us to the next practical point: a clean foam application usually also means less needless overspray in the room, because you’re not „working into the air“ with the finest mist, but with foam that goes where you need it.\u003c\/p\u003e\n\u003cp\u003eWhat many underrate: the combination of 9 litre volume, 3 bar working pressure and infinitely variable foam control doesn’t just make the system „stronger“, but above all more consistent. Consistency is quality in detailing: you want your foam to react on the first panel just like it does on the last. That cuts mistakes (too short a dwell time, too wet an application, too much product), saves the nerves and delivers repeatable results.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"solo","offers":[{"title":"9 liters \/ Acid (pH 1-7) 309 FA","offer_id":56938291790159,"sku":"D1-SOL-30931","price":74.8,"currency_code":"EUR","in_stock":true},{"title":"9 liters \/ Alkaline (pH 7-14) 309 FB","offer_id":56938291757391,"sku":"D1-SOL-30932","price":74.8,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/solo-cleanline-variofoam-309-fb-9-liter-schaumsprueher.png?v=1769852728"},{"product_id":"solo-cleanline-303-a-b-pumpsprueher-1-25-liter","title":"CLEANLine (303 A \/ B) Pump Sprayer 1.25 Litre","description":"\u003ch2\u003eOne pump sprayer, two chemistry worlds: solo CLEANLine (303 A \/ B) — Pump Sprayer 1.25 Litre\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eWhich pump sprayer suits your cleaner?

In detailing it's often not just the product that decides the result, but how you lay it down: too coarse = wasted product, too fine = it dries off, wrong seal = headaches. That's exactly where the CLEANLine series plays its strength: 303 A and 303 B are built the same technically, but sealed differently for the chemistry – so you run acidic and alkaline cleaners each in the right system. Both versions work manually with a piston pump up to 3 bar, have a safety valve to release the pressure and an adjustable hollow-cone nozzle for spray volume and pattern.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003epH-right instead of „it'll do“\u003c\/strong\u003e: 303 A uses FKM seals for acidic media (pH 1–7), 303 B EPDM seals for alkaline media (pH 7–14).

If you work with acidic specialist cleaners in detailing (classics: lime\/mineral-based deposits, water spots and rust film on suitable surfaces, depending on the product), then the A version is the logical grab – not because „A is better“, but because the seal matches the medium. The other way round, the \u003cstrong\u003eEPDM seal (303 B)\u003c\/strong\u003e is designed for alkaline cleaners in the pH 7–14 range; SOLO describes EPDM as the seal material for basic\/alkaline applications and also notes it suits disinfecting solutions. In practice that means: for typical all-purpose cleaners (APC) and many degreaser\/pre-wash scenarios you're very often in the green with 303 B, while 303 A is your safe bet when you deliberately work acidic. Our tip from the day-to-day: if you regularly spray both alkaline and acidic, genuinely grab both versions – that's not a gimmick, it's clean chemistry hygiene. And if you love your bottle parking spots: the CLEANLine even has a card\/label system in the spray head, including coloured marker cards – great for keeping contents and uses apart (and yes: it very effectively prevents the „oops, wrong cleaner“ moment).\u003c\/p\u003e\n\u003ch3\u003eCar pre-wash and detailing: applying cleaning chemistry in a controlled way with a pump sprayer\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCar pre-wash\u003c\/strong\u003e lives off chemistry clinging evenly and getting to work – not off you sending half of it into the air as mist. That's exactly what the 1.25-litre format is strong for: handy, quick to fill, and big enough to do a car in one go without topping up constantly (fill volume 1.25 L). The adjustable hollow-cone nozzle lets you trim the spray pattern so you get more coverage or more punch depending on panel size and dirt – without changing the character of the product. For us day-to-day that's the sweet spot for: pre-cleaners\/pre-sprays on lower areas, APC on sills\/door shuts (with the right pH version), and targeted wetting of problem zones.\u003c\/p\u003e\n\u003ch3\u003e3 bar spray pressure, hollow-cone nozzle, safety valve and continuous spraying for a clean pattern\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e3 bar spray pressure\u003c\/strong\u003e on a hand pump sprayer isn't a pub-talk number, it's the point where the spray pattern and your work rhythm get stable: pump, spray, keep going – without running „empty“ after three trigger pulls. SOLO quotes 3 bar for both 303 models and pairs it with a safety valve that can drop the pressure for emptying\/refilling and automatically vents over-pressure. On top of that there's the encapsulated pump unit, which shields the pump elements from the cleaning fluid being dispensed – a detail that in day-to-day simply means: less contact between the mechanism and aggressive chemistry, and so a more robust, more consistent function over time. And because we love it in detailing when things „just run“: the lock slider for continuous spraying is gold when you want to wet larger areas without sending your finger to the gym. If you need more of a „foam blanket“ than a spray film, take a look at one of our foam sprayers\/foamers as an add-on – the pump sprayer then stays your tool for pre-sprays, targeted wetting and working „by feel“.\u003c\/p\u003e","brand":"solo","offers":[{"title":"1.25 liters \/ Acid (pH 1-7) 303 A","offer_id":56938331111759,"sku":"D1-SOL-30301","price":18.33,"currency_code":"EUR","in_stock":true},{"title":"1.25 liters \/ Alkaline (pH 7-14) 303 B","offer_id":56938331078991,"sku":"D1-SOL-30302","price":18.33,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/solo-cleanline-303-a-pumpsprueher-1-25-liter.png?v=1769854142"},{"product_id":"solo-cleanline-304-a-b-pumpsprueher-2-liter","title":"CLEANLine (304 A \/ B) Pump Sprayer 2 Litres","description":"\u003ch2\u003eSpray on purpose, not by guesswork: solo CLEANLine (304 A \/ B) — 2-litre pump sprayer for clean, controlled chemical work\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eWhich solo CLEANLine (304 A \/ B) — 2-litre pump sprayer fits your cleaner? 304 A covers acidic to neutral media (pH 1–7) with FKM, 304 B handles neutral to alkaline media (pH 7–14) with EPDM – both up to 3 bar.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003esolo CLEANLine (304 A \/ B) — 2-litre pump sprayer\u003c\/strong\u003e is to detailing what a clean torque wrench is to mechanical work: control.

SOLO deliberately splits the CLEANLine by pH window: if you’re laying down concentrated or diluted acids in the pH 1–7 range, tools with FKM seals are the right pick; once it goes alkaline (pH 7–14), EPDM is the seal material that goes in. \u003c\/p\u003e\n\u003cp\u003eFor you as a detailer it translates beautifully into plain terms: if you run typical acidic jobs (say acidic cleaners that go after mineral residue and deposits), that belongs in the A world – and that’s exactly what 304 A is for. If your day-to-day runs more alkaline (classic: lots of pre-cleaner\/APC\/degreaser setups meant to break down organic grime), 304 B is the clean call. The point isn’t „acid good \/ alkali bad“ – the point is material compatibility and consistency: seals have to seal and move while they’re in contact with the medium. Mix it up wrong here and you rarely notice on the first spray – you notice later: pressure drops faster, the action gets rougher, small parts age for no reason.\u003c\/p\u003e\n\u003cp\u003eNice to know (because it really comes up in practice): with FKM, SOLO also mentions suitability for oil-based and partly chlorinated-hydrocarbon media. That’s no free pass for experiments, but it explains why a lot of pros like to stay in the FKM world for „chemically demanding“ media – as long as the pH use fits. And since we don’t do detailing in a lab but between the wheel, the sill and the door shut: if you run several media side by side, the A\/B logic is the simplest way to avoid mistakes. Label the contents, match the tool to it, done.\u003c\/p\u003e\n\u003ch3\u003eUsing 3 bar pump pressure, an encapsulated pump and an adjustable universal nozzle in detailing\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e3 bar pump pressure\u003c\/strong\u003e sounds technical at first – but it’s really the difference between „constantly re-pumping“ and „working in a clean flow“. With the 304s, SOLO describes how the efficient pump lets you reach an operating pressure of up to 3 bar with little effort, giving you long enough working intervals. That’s what makes the sprayer so pleasant in everyday car care: you can wet a panel evenly without the spray going tired after ten seconds.\u003c\/p\u003e\n\u003cp\u003eThe second pro building block is the fully encapsulated pump unit. SOLO explains that the encapsulated pump shields the pump elements from the chemically active cleaning fluid and so helps it last. Translated: less direct „chemical stress“ in the mechanical heart of the thing, less risk that the pump feel or the seal tightness gets worse over time – as long as you don’t treat the tool like a throwaway after use (more on that in a second).\u003c\/p\u003e\n\u003cp\u003eAnd then there’s the part you feel right away on every job: nozzle and handling. SOLO names a new, adjustable universal nozzle for a more balanced jet and spray pattern, and on the 304 B explicitly the adjustable hollow-cone nozzle, which lets you set spray volume and pattern. Add ergonomic controls, a comfortable trigger lever and a lock slide that lets you switch between continuous and spot spraying while you work. That’s pure gold in detailing: spot-on at badges, shut lines and edges – and the next moment broad across pre-wash zones, without cramping your hand or chopping up your workflow.\u003c\/p\u003e\n\u003cp\u003eBadly underrated, but a real quality indicator day-to-day: filling and standing. Per SOLO the tank is made of sturdy, UV-resistant polyethylene, stands on three feet, has a wide filler opening and a fill-level mark in the semi-transparent material. That’s not „nice“, that’s time saved: mix faster, spill less, set it down cleanly – and if you work professionally, those are exactly the details that make the session pleasant.\u003c\/p\u003e\n\u003ch3\u003eCleaning, releasing pressure and workflow tips for long enjoyment from your pump sprayer\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCleaning and releasing pressure\u003c\/strong\u003e on a pump sprayer isn’t the boring chore – it’s the part that preserves your spray quality. SOLO describes a safety valve you use to release the tank pressure for emptying, refilling or cleaning, and that any pressure above 3 bar is bled off automatically through this valve. For your routine that means: after working, bring the pressure down in a controlled way first, then open – not the other way round. That keeps it clean and predictable.\u003c\/p\u003e\n\u003cp\u003eIf you’re after consistent results in detailing, build yourself a simple routine: after use, empty the leftover medium, rinse with clean water, run one pass of water through it (so the nozzle and lines are clear too), then store it dry and clean. That stops residue drying on the valves and nozzle and ruining your spray pattern next time. And yes: with the more „active“ cleaners it pays off twice, because that way you don’t leave the seals sitting in the medium permanently.

The 5-litre tank, the oversized piston pump and the chemical-resistant flat-jet nozzle are built for pro work – whether it’s pre-wash, degreasing, workshop or vehicle cleaning. The variant is what matters: the 305 A runs FKM (Viton) for the acidic side, the 305 B runs EPDM for alkaline cleaners.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe right seal for the right chemistry.\u003c\/strong\u003e The 305 A (FKM\/Viton) is meant for acidic media in the pH 1–7 range, the 305 B (EPDM) for alkaline media in the pH 7–14 range – so the sprayer stays “tight” long-term and you work reliably instead of improvising.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA controlled spray pattern instead of mist lottery.\u003c\/strong\u003e The flat-jet nozzle lays the liquid down in an even band – ideal when you want to wet a surface without dragging everything around it into the mix.

Depending on the job, detailing throws very different formulas at you: wheel cleaners tend to lean acidic, while lots of pre-cleaners and all-purpose cleaners lean alkaline, and then you’ve got alcohol-based mixes or degreasers on top. This is exactly where SOLO splits the variants strictly by use: the 305 A is intended for acidic media in the pH 1–7 range and runs FKM seals; the 305 B is meant for alkaline media in the pH 7–14 range and uses EPDM. That’s not a marketing gimmick, it’s materials science: elastomers behave differently depending on the chemistry – and the best pump is useless if the seals swell, harden or simply start leaking. So if you regularly switch between “more acidic” and “more alkaline”, matching them up properly is the basis for predictable results and stress-free work.\u003c\/p\u003e\n\u003ch3\u003eUse in detailing: pre-wash, wheels, engine bay \u0026amp; workshop – how to really use 5 litres efficiently\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePre-wash and alkaline cleaners\u003c\/strong\u003e are the sweet spot for a lot of people – and that’s exactly what the 305 B (EPDM, pH 7–14) is built for: you wet large panels fast and evenly, let the surfactants do their thing and cut down on mechanical contact in the next step, because the dirt has already been “loosened”. For acidic jobs (depending on the product logic, e.g. when you’re going after limescale or certain mineral deposits) the 305 A (FKM, pH 1–7) fits – the key is to always stick to the intended medium instead of playing “it’ll probably be fine”. Day-to-day that means: you use the sprayer as an application tool, not a stand-in for a foam lance. For real foam dwell time you grab a dedicated foam sprayer; the CLEANLine 305 is made to lay liquids down under control.\u003c\/p\u003e\n\u003ch3\u003eSpray pattern, 3 bar build-up and handling: why the CLEANLine 305 A\/B feels so “pro”\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e3 bar working pressure and a flat-jet nozzle\u003c\/strong\u003e are the combo that just works day in, day out: you get an even film of liquid instead of a random landscape of droplets. Max spray pressure sits at 3 bar; the oversized piston pump builds it up in just a few strokes – you notice that straight away when you’re working larger panels and don’t want to top up the pressure every 20 seconds. The 5-litre tank is deliberately built tough; the CLEANLine catalogue highlights, among other things, the very high tank robustness for the 305 models (including a 7 mm wall thickness) plus a carry strap, a base foot and ergonomic controls. In practice that means: a stable stance while pumping, clean handling when you move it around and less “fiddling” during breaks, because the lance can be stowed properly. The key specs are clearly trimmed for everyday work too: 5 L nominal volume, a 50 cm spray tube and a 1.4 m hose, plus an empty weight of around 2.6 kg (depending on model\/spec) – compact enough for the car, but big enough for serious surfaces. And yes: a safety\/relief valve for releasing pressure is part of the deal, so you can let the pressure off under control instead of fighting the cap.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"solo","offers":[{"title":"2 liters \/ Acid (pH 1-7) 305 A","offer_id":56938499080527,"sku":"D1-SOL-30505","price":62.32,"currency_code":"EUR","in_stock":true},{"title":"2 liters \/ Alkaline (pH 7-14) 305 B","offer_id":56938499047759,"sku":"D1-SOL-30506","price":62.32,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/solo-cleanline-305-b-pumpsprueher-5-liter.png?v=1769856475"},{"product_id":"solo-cleanline-360-b-akku-spruehflasche-1-liter","title":"CLEANLine (360 B) Cordless Spray Bottle 1 Litre (3,7 V \/ 1,4 Ah)","description":"\u003ch2\u003eMore control, less effort: solo CLEANLine (360 B) — Cordless Spray Bottle 1 Litre (3,7 V \/ 1,4 Ah)\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eIs the solo CLEANLine 360 B a good cordless spray bottle for car care?

What matters isn't the buzzword but the media fit: it's designed to put out alkaline, neutral to mildly acidic cleaners plus alcohol-based disinfectant cleaners. In car care that's a great match for plenty of everyday jobs: alkaline pre-cleaners for organic grime (grease\/oil\/protein), neutral all-rounders for sensitive areas, and glass products you'd rather lay down as a fine mist than „flood“ on.\u003c\/p\u003e\n\u003cp\u003eThe 1-litre tank with a fill-level mark isn't a side detail – it sets the pace of your workflow: 1 litre is enough to cover several steps on one car (say interior + glass + smaller exterior spots) without wrestling a huge jug. And because the bottle is steady on its feet, you can set it down mid-job without it tipping at the slightest knock – sounds trivial, but it saves you exactly the kind of hassle you never want in detailing.\u003c\/p\u003e\n\u003ch3\u003eAdjustable hollow-cone nozzle, EPDM seals and chemical compatibility\u003c\/h3\u003e\n\u003cp\u003eIf a spray bottle is meant to be „pro“ in detailing, it comes down to two things: \u003cstrong\u003espray-pattern control\u003c\/strong\u003e and material resistance. The 360 B ships with an adjustable hollow-cone universal nozzle that, per the product information, is stepless from a fine spray mist to a pinpoint jet. Handy, because you can adapt droplet size and coverage: mist for even dwell on big parts (door cards, carpet, glass), a tight jet for precise work on edges, in grab handles or around badges.\u003c\/p\u003e\n\u003cp\u003eJust as important: the seals are EPDM. For you, day-to-day, that means solid resistance against plenty of water-based cleaners – exactly the product world we live in for professional detailing. Still (as always): chemistry is no one-size-fits-all. „Suitable for alkaline, neutral to mildly acidic“ is clear guidance, but you shouldn't just run very aggressive, heavily solvent-based special mixes blind. Our detailing approach: match the medium to the surface, set a sensible concentration, and when you combine a new product, do a quick material test on a hidden spot first – not out of fear, but because that's how pros work.\u003c\/p\u003e\n\u003cp\u003eA really nice day-to-day detail is the flexible suction tube, which per the datasheet even lets you spray overhead. In the car that's no gimmick but genuinely useful in real situations: under dash edges, around the boot lid, on door shuts, or when you're working vertical panels and can't always hold the perfect „bottle down“ angle. On top of that: the maker names chemical-resistant components and „every last drop“ dispensing thanks to the tube inside the tank – so you use more of what you mix instead of tipping out half a sediment at the end.\u003c\/p\u003e\n\u003ch3\u003eUse in car care: pre-cleaning, glass cleaning and efficient surface coverage\u003c\/h3\u003e\n\u003cp\u003eDay-to-day the 360 B works best when you treat it like a toolbox: \u003cstrong\u003eright medium + right spray pattern + right order\u003c\/strong\u003e. For exterior work it's strong when you want to coat small to mid-sized areas evenly – pre-cleaner on the lower side panels, bug remover on spots, or a pH-neutral product as a „glide film“ before wiping.\u003c\/p\u003e\n\u003cp\u003eInside, controlled coverage is often even more important: you want to wet, loosen, lift – without flooding everything. This is where the stepless nozzle shows its strength: fine mist on fabric or plastic, short dwell, then back it up mechanically (brush\/detailing brush) and lift with microfibres. Especially with organic grime (grease, oil, protein) – which the datasheet names as a target – even lay-down is the difference, so the surfactants work everywhere.\u003c\/p\u003e\n\u003cp\u003eOn glass the 360 B is a bit of a quiet secret in pro day-to-day: mist instead of drops cuts the risk of catching product edges and streaks. You spray fine, spread briefly, wipe off, done. And because the unit is only 0,3 kg empty, it's comfortable to handle without feeling like you've just trained forearms like a racoon at the gym after two windows. Charging is fuss-free over USB, the cable's in the box per the scope of delivery – just as handy at home as on the road.\u003c\/p\u003e\n\u003cp\u003eWhat it comes down to in the end: the 360 B isn't a „magic bottle“, it's a precision accelerator. It takes the pumping off your hands, keeps your lay-down constant and lets you work cleaner. And in detailing that's often the difference between „somehow clean“ and „looks like a pro did it“ – not louder, not more frantic, just with more control.\u003c\/p\u003e","brand":"solo","offers":[{"title":"1 liter \/ Alkaline (pH 7-14) 360 B","offer_id":56938525131087,"sku":"D1-SOL-36001","price":34.01,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/solo-cleanline-360-b-akku-spruehflasche-1-liter.png?v=1769858161"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/collections\/detailing1_scholl-concepts_logo_2f8db01e-b86f-48e1-9365-5444203cfa78.png?v=1769771707","url":"https:\/\/detailing1.at\/en\/collections\/solo.oembed","provider":"Detailing1","version":"1.0","type":"link"}
