Koch Chemie GSF Gentle Snow Foam | pH 7.5 Neutral | Coating-Safe Pre-Wash
Koch Chemie GSF Gentle Snow Foam — pH-Neutral Pre-Wash
Gentle Snow Foam is a thick, high-clinging pre-wash foam with one big advantage: it's genuinely pH-neutral at pH 7.5. That means it softens and lifts loose dirt on contact but won't strip the wax or sealant underneath — so you can pre-wash as often as you like without undoing your protection.
Foam first, touch less
The point of a pre-wash is to remove grit before your mitt ever touches the paint. A clinging foam gives the surfactants time to dwell and lift abrasive particles, cutting the risk of wash marring. It carries a pleasant cherry fragrance while it works.
How to use it
Through a foam cannon, dilute around 20 ml per litre in the bottle; as a hand-wash shampoo, about 50 ml to 10 L. Foam the panels, let it dwell without drying, then rinse thoroughly before your contact wash.

Alkaline lifts organic grime, acid dissolves minerals, neutral foams and washes without stripping your protection. Pick a product for each step from whichever brand you like — the neutral foam is optional.
