SONAX XTREME Upholstery+Alcantara Cleaner Textile Cleaner 400ml

Deep-clean fabric seats, Alcantara and headliners — SONAX XTREME Upholstery+Alcantara Cleaner

What can the SONAX XTREME Upholstery+Alcantara Cleaner do? This foaming cleaner with enzymatic odour control pulls dirt and smells deep out of upholstery, Alcantara, headliners and carpet — without soaking the fabric or leaving rings.

Upholstery and Alcantara inside the car take a daily beating: seat wear, food spills, sweat residue, pet hair and trapped smells build up in the fibres over months, and a quick vacuum on its own won't get all of it out. What you need is a cleaner that works deep into the fibre structure, breaks dirt down chemically, and at the same time neutralises smells for good — not just masks them. That's exactly what the SONAX XTREME Upholstery+Alcantara Cleaner does: a foaming cleaner with enzymatic odour control for every textile surface in the cabin. The 400 ml aerosol can keeps the job simple, and the foam technology gives you a gentle, deep clean without soaking the upholstery through.

• Foam technology for a deep clean without soaking the fabric. The fine-pored foam works deep into the fibre structure, lifts embedded dirt and is then brushed out or picked up with a cloth — without overwetting the upholstery. Less moisture means faster drying and no risk of mould if the car isn't well aired.
• Enzymatic odour control gets rid of smells for good. Cigarette smoke, pet smells, food odours and sweat aren't just a dirt problem — they're a chemical one: the odour molecules are lodged in the fibres and you can't get rid of them by covering them up. The enzymatic formula breaks down the molecular structure of the substances causing the smell — so you end up with lasting freshness instead of a quick spritz of fragrance.
• Safe on Alcantara, no greying or fibre damage. Alcantara reacts badly to the wrong products — anything too harsh can mat the fibres, cause discolouration or kill that soft feel for good. The XTREME Upholstery+Alcantara Cleaner formula is approved for Alcantara and won't change the fibres when you use it properly.

Detailing1's tip from the shop: Vacuum the area thoroughly before you start — foam cleaners work better on a surface that's already roughly clean, because they're meant to sink into the fibres, not into loose grit. Always do a whole connected area in one go — the entire seat panel in a single pass, never just the one stain. That keeps drying rings from forming at the edges. After cleaning with a brush or cloth, vacuum the area dry, then leave it to dry with the doors open.

Foam cleaner technology — why foam beats liquid cleaners on upholstery

Choosing between a spray liquid and a foam isn't a trivial call on upholstery cleaners. Liquid cleaners flow easily — they sink deep into the upholstery, which on one hand gives you a thorough clean, but on the other brings the risk of soaking the fabric through: seats that take on too much moisture need long drying times and can encourage mould in the foam padding if they don't dry properly. Foam has a controlled viscosity: it clings to the surface and works into the fibre structure without saturating the material. The cleaning agents in it spread evenly through the foam structure and act right where the dirt sits, on the fibre surface. After the dwell time you work the foam out mechanically with a soft brush or a microfibre cloth, and it carries the loosened dirt with it. The result: a more thorough clean with less moisture. For a cabin you want back in use as soon as possible after cleaning, that's a real practical edge. One more thing: foam is easier to apply to vertical and sloped surfaces than liquid cleaners, which would run straight off. That makes the job easier and lower-risk on seat bolsters, door cards and headliners.

The enzymatic side works hand in hand with the mechanical foam cleaning: enzymes are biological catalysts that break down organic substances like proteins (sweat, food residue), fats and odour molecules at the molecular level. That's why enzymatic cleaners work on smells for good — they take out the cause, not the symptom. Compared to purely fragranced interior cleaners that just mask smells, the enzymatic action is far more lasting: the smell doesn't come back, because the molecules causing it are no longer there.

Foam technology also has a safety edge: spraying doesn't throw out coarse droplets that can get in your eyes — the fine foam stays on the surface and doesn't run off where it shouldn't. That makes the job safer and cleaner in the tight cabin than spray liquids. For interior work where you're up close to the surface, that's an everyday point that matters. There's an economic side too: foam goes further than liquid because it bulks up its volume with air and spreads the cleaning agent evenly across the surface without saturating it. A 400 ml can lasts for several full seat cleans.

One more thing that matters day-to-day: anyone who runs the car with pets knows how stubbornly animal and food smells cling to upholstery. The odour molecules are adsorbed by the fibres and settle deep inside the padding — a surface freshen-up with a fragrance spray masks the smell for a bit but doesn't get rid of it. Enzymatic cleaners are the only lasting fix here, because they break down the proteins causing the smell. For dog owners and families with small kids, reaching for an enzymatic foam cleaner regularly is less a luxury than a must for a cabin that stays fresh. Especially in the warmer months, when temperatures in a parked car ramp up smell development, a regular upholstery clean really pays off.

How to use the XTREME Upholstery+Alcantara Cleaner properly

How you go about it makes the difference. Start by vacuuming the area thoroughly — a brush attachment lifts surface dust and hair that would otherwise block the foam from reaching deep. Then spray the foam evenly over the surface and work it straight in with a soft upholstery brush or microfibre cloth in circular motions. The foam should visibly froth up and pick up dirt. Important: always do the whole connected area in one pass — half a seat and a stop leaves visible drying rings at the line between cleaned and uncleaned fabric. After a dwell time of 1–3 minutes, lift the foam with a clean cloth or pick it up with a vacuum. On heavily soiled upholstery a second round may be needed. Then leave the area to dry with the windows or doors open — a small fan can cut drying time to under an hour. On Alcantara: use a very soft brush and work with the grain of the fibres, not against it — that stops greying and keeps the soft texture.

Headliners call for extra care: too much moisture can loosen the adhesive on the trim and cause it to sag. Apply the foam sparingly here, don't let it dwell long, and wipe with only light pressure. A vacuum straight after helps cut the moisture quickly. On badly loosened or yellowed headliners, professional reconditioning is the way to go.

An often underrated use is cleaning the footwell carpet. Floor mats and carpets in the car pick up dirt, sand, road salt in winter and moisture off shoes over months — and carry all that straight into the carpet fibres. Foam works great here too: the carpet doesn't get soaked, the foam works near the surface in the fibre. After brushing it out, pick it up with a carpet or upholstery attachment on the vacuum. For stubbornly dirty footwells a second pass may be needed. If you've pulled the mats out, you can clean them even more effectively — foam them on a plastic sheet or tarp outside, brush them in, rinse with a little water and leave to dry in the shade. The result is far better than cleaning them in place.

Where it works — the materials and situations it suits best

The SONAX XTREME Upholstery+Alcantara Cleaner is built for every textile and Alcantara surface in the cabin: fabric seats and upholstery, Alcantara seat bolsters and steering wheel covers, headliners, carpets and door cards with a textile section. Especially good on dirt from coffee, cola, chocolate, denim rub-off, pet hair and skin oils. The enzymatic odour control makes it particularly valuable on cars shared with pets, used cars with smoke smell baked in, or cars that regularly haul food. What it can't do: deep oil stains, paint and similar inorganic substances — those need dedicated solvent cleaners. Use a separate leather cleaner on leather surfaces; the Upholstery+Alcantara Cleaner isn't meant for smooth leather. On velour and similar velvety surfaces, test on a hidden spot first, as these materials can sometimes react more sensitively to foam cleaners than standard upholstery.

Another use worth flagging is the seasonal clean after winter. Salt and grit off wet winter shoes settle in the carpet and the lowest layers of the upholstery and can attack the material over time. A thorough spring clean with the upholstery cleaner takes out that residue before it does any lasting damage. At the same time, it neutralises the winter smells that crept in — damp clothes, heater air, dog paws. That makes a spring interior clean one of the most effective steps for a fresh cabin across the whole season. If you do a full interior clean twice a year — spring and autumn — you keep upholstery and materials in a state that means a deep recondition is needed less often.

Compared — XTREME Upholstery+Alcantara Cleaner vs. Stain Remover vs. propellant-free cleaner

The SONAX XTREME range has three upholstery cleaner products, each with a different focus. The XTREME Upholstery+Alcantara Stain Remover is a spot cleaner for tackling single stains — you apply it straight to the stain and can use it without cleaning the whole surface. Ideal for fresh stains or as a first treatment in the car. The SONAX XTREME Upholstery+Alcantara Cleaner, on the other hand, is built for whole-surface cleaning — for when you want to clean the entire seat panel or a larger area. The XTREME Upholstery+Alcantara Cleaner (propellant-free) is the more eco-friendly option without aerosol propellant, with the same cleaning effect. If you'd rather skip aerosol products or work in closed spaces without good ventilation, reach for the propellant-free version. The cleaning effect is comparable. So the choice comes down to the situation: single stain → Stain Remover; whole-surface clean with aerosol → this textile cleaner; whole-surface clean the eco way → propellant-free version.

A smart combo in the detailing workflow is to use both products: first spot-treat fresh or stubborn single stains with the Stain Remover, then freshen the whole surface evenly with the textile cleaner. That saves time, because you don't have to concentrate the foam cleaner on spot-treated areas, and it gives an even result across the whole seat panel with no visible difference between treated and untreated zones. Pro detailers run exactly this two-step method day-to-day and get the best results on upholstery work with it. As a final step after drying, an impregnation spray for upholstery and textiles is worth it — it builds a protective layer that repels new dirt and makes the next clean far easier. That full interior routine — clean, neutralise smells, then impregnate — is the optimum for car textiles that stay fresh long-term.

Buying advice — when this textile cleaner is the right call

The SONAX XTREME Upholstery+Alcantara Cleaner is for anyone who wants to clean the cabin regularly and thoroughly — whether as part of a seasonal interior clean, after buying a used car, or after heavy use with family, pets or regular food runs. The 400 ml aerosol can lasts for several full interior cleans. The XTREME Interior Cleaner combo — hard/universal for plastics and soft/textile for upholstery — covers the whole cabin in one care workflow. For pro detailers doing used-car preps daily, it's a solid standard tool for interior reconditioning. The simple aerosol application lets you work fast, and the reliable odour control solves one of the most common customer gripes on used cars. Next time you're stood in front of a car with a worn cabin that smells of old fabric and smoke, reach for the Upholstery+Alcantara Cleaner — and see what a good enzymatic foam cleaner can do for an interior.

For detailers upgrading used cars: cleaning the interior with a quality foam cleaner is often the single most noticeable step in a used-car prep — customers spot straight away whether a cabin smells fresh and looks clean. That has a big effect on a car's perceived value. With a product like this that works reliably and delivers results in a short time, interior reconditioning isn't just a box to tick but a real quality marker that makes the difference.

Bottom line: the textile cleaner is the right call for anyone who wants to deep-clean a whole car interior rather than just treat single stains. The mix of foam technology, enzymatic odour control and Alcantara compatibility makes it the all-rounder for interior cleaning. Once you've seen how a freshly cleaned cabin changes the drive, you won't want to skip a regular upholstery clean again. The 400 ml size is good for 2–4 full interior treatments — depending on the car and how dirty it is. For regular pro work, buying in bigger quantity pays off, so you've always got fresh stock on hand and avoid breaks in the detailing workflow. The aerosol can is easy to store and stays on hand for the next interior clean. Kept cool and dry, the product holds its full effectiveness for a long time — another edge over liquid cleaners, which can lose effect faster once opened.
