ZviZZer Sour Shampoo Car Shampoo 1000ml

Lift off water spots and limescale without touching the coating

What is the ZviZZer Sour Shampoo? An acidic car shampoo with a pH of 3.4 to 3.8 that dissolves and neutralises mineral deposits like limescale and water spots. It freshens up the beading on ceramic-coated paint without attacking the sealant. Not meant as a weekly shampoo, and not for shifting tar, bugs or organic grime.

Acidic car shampoo describes a shampoo whose pH sits in the acidic range. The ZviZZer Sour Shampoo is one such acidic car shampoo from ZviZZer, with a pH of 3.4 to 3.8. Its acidic surfactants dissolve the mineral deposits a neutral shampoo leaves behind, and neutralise alkaline residue from earlier cleaners. You can run it the classic two-bucket way or as active foam through the snow foam lance, and it's tuned for looking after ceramic-coated vehicles.

• Dissolves water spots and limescale instead of hiding them. The acidic pH of 3.4 to 3.8 goes straight for the mineral deposits a neutral shampoo just slides over. Dried-on water spots from hard tap water or lawn sprinklers come off in the normal wash, so you don't have to polish each one out by hand.
• Freshens up the beading on your sealant. Mineral films settle over a ceramic coating like a veil and slow the water run-off. An acid wash roughly every 4 to 8 washes strips that veil away and brings the beading back, instead of laying down a fresh layer. That keeps the sealant you already have visibly tight for longer.
• One litre, two ways to use it. 15 to 30 ml in 5 litres of water is plenty for the two-bucket wash, about 15 ml in 1 litre for the snow foam lance. Depending on your dose, a 1-litre bottle gets you around 30 to 60 washes, since the shampoo isn't in play on every single wash.

Detailing1's tip from the shop: The most common mistake with an acidic shampoo is reaching for it every week like a normal one. It's a care product, not an everyday cleaner, and it only belongs in the bucket roughly every four to eight washes. Second mistake: sun and hot paint. On a black car parked out front of our Nordhorn showroom in the June sun, the foam flashed off in seconds and left streaks. Work in the shade on cool paint, keep it wet, rinse thoroughly.

As foam or two-bucket on cool paint

You lay the acidic car shampoo down as active foam at about 15 ml in 1 litre through the snow foam lance, or at 15 to 30 ml in 5 litres in the bucket.

Rinse the paint thoroughly first to clear off coarse grit, then let the shampoo dwell and work top to bottom with a soft microfibre cloth or wash mitt. Then rinse it all off with a strong jet or pressure washer while the surface is still wet.

Work in the shade on cool paint and don't let the shampoo flash off. With hard tap water, dry the car with a leather or blow it off after rinsing, otherwise the same water lays down fresh spots right where you just removed them. Wear gloves and eye protection, since the formula is acidic and an irritant.

Minerals yes, tar and bugs no

The Sour Shampoo is built for mineral grime: it reliably dissolves limescale, water spots and alkaline cleaner residue, but for organic or greasy dirt it's the wrong tool.

Its home turf is recurring maintenance decontamination. Where a neutral shampoo only takes the loose dirt with it, the acidic pH bites into the dried-on minerals and brings back a clear, evenly beading finish. On a ceramic-coated bonnet that had gone hazy after a summer of lawn-sprinkler overspray, the beading came back in a single wash, with no need to re-seal.

The limits are clear: tar, bug splatter, tree sap and brake dust stay jobs for the dedicated products — an acidic shampoo won't touch them. When it's just regular maintenance washing with no mineral issue, reach for the mild Allround Shampoo. When water spots or fading beading are the problem, reach for this acidic one. Acidic cleaners also don't belong on bare, unprotected brakes or raw aluminium.

For the coating keeper, not the weekly wash

The Sour Shampoo is the right call when you're looking after a ceramic coating and want to keep its beading visible for months without jumping straight to a re-seal.

Because it works both as a bucket shampoo and as snow foam, it slots into your existing wash workflow and needs no special kit beyond the snow foam lance. It's part of our washing and cleaning range, where it sits alongside the neutral Allround Shampoo as a targeted care step for hard-worked or sealed paint.

It's less suited to anyone after a single shampoo for every wash, because an acidic pH is needlessly harsh for that and not needed long term. If you need both — regular washing and the occasional mineral decontamination — you're better off with the neutral-and-acidic duo than with one compromise.

The one thing most people miss: water spots aren't surface dirt, they're dried-on mineral that mechanically only comes off by polishing — which means removing paint. That's exactly what an acidic shampoo saves you, dissolving the minerals chemically before they lock in. Wash acidic once every four to eight washes and you polish less often and spare the clear coat, which every polish thins out a little more.

Anwendung des ZviZZer Sour Shampoo

Mineralien lösen ohne neue Wasserflecken zu setzen

Den Lack zuerst gründlich mit Wasser abspülen, damit grober Sand und loser Schmutz weg sind und beim Waschen keine Kratzer entstehen. Erst danach kommt das saure Shampoo ins Spiel.

Als aktiven Schaum etwa 15 ml Sour Shampoo auf 1 Liter Wasser in die Schaumkanone geben und auftragen. Für die klassische Zwei-Eimer-Wäsche 15 bis 30 ml auf 5 Liter Wasser dosieren und aufschäumen lassen. Kurz einwirken lassen, dann mit einem weichen Mikrofasertuch oder Waschhandschuh von oben nach unten arbeiten.

Anschließend mit kräftigem Wasserstrahl oder Hochdruckreiniger restlos abspülen, solange die Fläche noch nass ist. Bei hartem Leitungswasser das Fahrzeug danach abledern oder abblasen, sonst setzt das trocknende Wasser genau die Flecken, die du gerade entfernt hast.

Das Sour Shampoo ist kein Wochenshampoo, sondern eine Pflegestufe etwa alle vier bis acht Wäschen, wenn Wasserflecken oder ein schwächeres Abperlen sichtbar werden. Für die übrigen Wäschen das milde Allround Shampoo nehmen.

Hinweise: Immer im Schatten auf kühlem Lack arbeiten und das Shampoo nicht antrocknen lassen, sonst drohen Schlieren. Auf heißem Lack in der Sonne niemals anwenden. Da die Rezeptur sauer und reizend ist, Handschuhe und Augenschutz tragen und Kontakt mit Augen und Haut vermeiden. Säurehaltige Reiniger gehören nicht auf blanke, ungeschützte Bremsanlagen oder rohes Aluminium, sondern nur auf lackierte oder versiegelte Flächen. Für organischen Schmutz wie Teer, Insekten oder Baumharz ist das Shampoo nicht gemacht. Kühl und frostfrei lagern.
