Koch-Chemie

Koch-Chemie (Koch-Chemie GmbH, headquartered in Unna, Germany) has supplied professional car care chemistry to body shops, detailing studios, and vehicle preparation workshops since 1968. The brand is carried in the US primarily through kcxusa.com and select professional distributors, with their consumer line expanding on Amazon.

The German engineering approach shows up in formulation detail — Koch-Chemie products favor precision over fragrance marketing, often listing pH values directly on the label ("pH 7.5") and formulating to strict performance specifications. Their Gentle Snow Foam (GSF) is one of the better-known products among US enthusiasts who follow European detailing forums, praised for its foam density and coating-safe pH.
