Koch Chemie Gentle Snow Foam GSF pH Neutral 1L

Notify me when this product is available:

Koch Chemie Gentle Snow Foam (GSF) is a pH-neutral, gentle snow foam designed to safely and easily remove dirt and grime from the exterior of your vehicle.

GSF features a high-foaming formula that will produce a blanket of foam that sits on the surface and encapsulate dirt particles, pulling them from the paint for safe and easy removal. 

Due to its pH neutral formula it will not corrode any existing protective layer, making it a great maintenance option.

Gentle Snow Foam can also be put into the bucket and used as normal car shampoo.

It does not contain any sealing components, so it is perfect as a pre-wash before sealing.

Gentle Snow Foam can be enriched with Green Star to create an active foam in order to quickly remove stubborn dirt and insects.

Areas of Use

All external surfaces on cars, trucks and also caravans or mobile homes.


    • Foam Cannon: mix approx. 150ml with 1L water
    • Foam Sprayer: mix approx. 30ml with 1L water
    • Hand Wash: mix approx. 50ml with 10L warm water
    • Spray the car completely and conclusively with Gentle Snow Foam
    • Let the cleaner work for 5-6 minutes
    • Rinse completely with water
    • To quickly remove stubborn dirt and insects add 30ml of Green Star to 1L GSF solution. This increases the pH value and improves cleaning performance even more. But be careful, now waxes are also washed off the car

    A General Application Guide

    The below graph is an indicator of what products are best suited as a maintenance pre-wash, depending on the protective products that are on the surface. It's up to the user to decide on the amount of chemical energy required to safely remove as much contamination as possible. Even though the best course of action is to wash frequently, limiting the amount of chemical energy required, it's not always achievable, so we've also listed what options are suitable for occasional use after longer periods between washes.
