Koch Chemie Active Foam | Alkaline Active Foam (1 L)

Dense active foam that dissolves grease without scrubbing

Koch Chemie Active Foam is a highly concentrated alkaline foam that leaves your car clean with minimal effort. Thanks to its extremely high content of anionic surfactants, it creates a dense foam that clings to the surface, penetrates deep into layers of dirt, and effectively dissolves grease and road grime.

Its special formula not only ensures intensive cleaning performance, but also supports the self-cleaning effect of car washes, extending the service life of their brushes. Active Foam contains no phosphates or NTA, making it gentle on your car’s surface and the environment.

The luxurious sandalwood fragrance makes washing a pleasant experience. The product is suitable for both pressure washers and manual foam sprayers, and is also optimized for biological treatment plants for process water.
