Koch Chemie (AS) AutoShampoo | Vehicle Shampoo 1L

Koch Chemie AutoShampoo (AS) is a concentrated, high-foaming car wash shampoo that offers powerful yet safe cleaning, whether you’re using a foam cannon or a traditional bucket wash.

AutoShampoo (AS) is Koch Chemie’s answer for detailers and enthusiasts who want a reliable, no-nonsense car wash liquid that gets the job done properly. Its pH-balanced, lightly alkaline formula (pH 9) provides stronger cleaning performance than a standard ph neutral car wash, yet it’s still gentle enough to preserve waxes, sealants, and coatings.

This car wash soap combines both anionic and non-ionic surfactants to attack dirt and road film from multiple angles, ensuring thorough cleaning without harsh chemicals. Because it’s phosphate and NTA free, it’s a safer option for both your vehicle and the environment, making it one of the most dependable car wash products available.

Despite its strong cleaning ability, AS remains cost-effective. A single 1L bottle covers around 8 full washes, with dilution ratios designed for flexibility. Use it in a foam cannon for a thick, clinging snow foam, or dilute it in a wash bucket as a slick, lubricating car shampoo that helps prevent wash-induced marring.

If you’re after one of the best car shampoos for maintaining protection while still cutting through grime, AutoShampoo is a trusted choice.
