Labocosmetica Purifica Review & How-to Guide: The First Acid Decontaminant Shampoo
Purifica is Labocosmetica's pH-3 acid decontaminant shampoo — the first acid car shampoo — made to dissolve the thin, often invisible film of limescale and mineral deposits that water leaves behind and that dulls paint, most visibly on dark cars. It stays effective even at high dilution and is coating-, sealant- and trim-safe (VDA certified). Dilute 1:400 in a bucket for maintenance, or 1:5–1:10 in a foam gun as a pre-wash.

Labocosmetica Purifica — pH 3 (acid) · categories: Bucket Car Shampoo, Pre-washing (Pretreatment) · concentrate, dilution-flexible.
| Use scenario | Dilution | Effective pH | Notes |
|---|---|---|---|
| Coating-maintenance bucket wash | 1:400 (≈4 caps / 10 L) | ~5 | routine descaling, coating-safe |
| Sprayer pre-wash | 1:200 (1 cap / 2 L) | 3 | spray the whole car, then shampoo wash |
| Foam-gun, 3pH cycle step 1 | 1:10 | <3 | acid → neutral → alkaline routine |
| Foam-cannon pre-wash (after mineral-heavy rain) | 1:5 | <3 | pair with mechanical agitation |
| Stubborn limescale / rim renewal | 1:30 | <3 | onto surface, wash glove or brush |
Approximate effective pH by dilution (manufacturer): 1:100–1:200 → pH 3 · 1:201–1:330 → pH 4 · 1:301–1:400 → pH 5.
How to use
Work on cool, shaded panels. As a pre-wash, dilute into a foam gun (1:10) or foam cannon (1:5), cover the car, let it dwell a few minutes without drying, then rinse thoroughly with a pressure washer. For contact washing, use 1:400 in the bucket. Purifica is designed as the acidic first step of a 3-pH routine — acid (Purifica) to lift minerals, then a neutral shampoo, and an alkaline pre-wash only if organic grime demands it. For visible limescale or rim renewal, apply a 1:30 solution with a glove or brush and agitate.
Why it's notable
Purifica was the first acid shampoo built for car detailing. Unlike a neutral maintenance shampoo, it specifically sequesters inorganic limescale and mineral film — the haze that makes dark paint look flat — and keeps descaling power even when heavily diluted (down to 1:400). It carries no waxes or sealants, so it cleans coated paint without smearing or building up, and holds VDA material-safety certification for use on delicate surfaces.
Cautions & constraints
Purifica is a decontaminant, not an everyday do-everything shampoo. It targets minerals and limescale — it is not an iron-fallout remover (use a dedicated iron remover for bonded fallout) and not an alkaline degreaser for heavy organic traffic film. As with any acidic product, work on cool, shaded panels, never let it dry, and rinse fully; spot-test first on bare polished metal, raw alloys or unknown trim. At the manufacturer's recommended dilutions it is rated coating-, sealant- and trim-safe.
Community & independent testing
On the Detailing World forum, users ran Purifica both as a foam pre-wash and as a contact wash and reported improved hydrophobicity and fewer water spots; several noted a ~1:10 solution on a mitt brought "a noticeable improvement" to the performance of an existing coating. Independent video reviews such as DIY Detail on YouTube put an acid decontaminant shampoo against a long-lived ceramic coating to test whether it revives beading. Public feedback consistently frames Purifica as an effective descaler, not a substitute for iron or tar decontamination.
FAQ
Is Labocosmetica Purifica safe on ceramic coatings?
At label dilutions the manufacturer rates it coating- and sealant-safe (VDA certified), and it contains no waxes or sealants to smear. Detailing World users reported it actually improved hydrophobicity on coated paint.
What dilution should I use for a normal maintenance wash?
About 1:400 in a bucket (≈4 caps per 10 L), which lands near pH 5 — enough to lift mineral film without stripping protection. As a pre-wash, use 1:5–1:10 in a foam gun or cannon.
Does Purifica remove iron fallout or etched water spots?
It dissolves inorganic limescale and light mineral/water-spot film and can reduce fresh spotting. For bonded iron fallout use a dedicated iron remover; deeply etched water spots may still need a stronger water-spot remover or machine polishing.
