Koch Chemie Active Foam (AF) is a concentrated, mild alkaline car wash shampoo that packs serious cleaning strength, perfect when you need more bite than a standard pH neutral car wash.

Koch Chemie AF isn’t just another car wash liquid. It’s a carefully formulated snow foam and car shampoo with a pH of 9.5, built to strip away stubborn dirt, grease, and road grime without damaging paint, wheels, or glass. That mild alkalinity gives it far more cleaning punch than a neutral car wash soap like Koch Chemie GSF, yet it remains safe and effective when diluted correctly.

The solution is phosphate and NTA free, making it a smarter option for detailers who want maximum cleaning efficiency without harsh or unnecessary additives. Used through a foam cannon, it produces a dense, clinging snow foam that softens and lifts heavy contamination before you make contact. In a wash bucket, it works as a traditional car wash detergent: slick, lubricating, and highly effective.

One of the standouts of Active Foam is the fragrance. Koch Chemie infused this formula with a distinctive sandalwood scent, leaving behind a refined, woody note that lingers throughout the wash process. It’s not only powerful, it makes the job feel more enjoyable compared to typical harsh-smelling car wash products.

For enthusiasts and professionals looking for one of the best car shampoos when it comes to deep cleaning power, Active Foam delivers every time.
