Koch Chemie Multi Star N (MSN) is a highly concentrated alkaline pre-wash cleaner engineered for commercial car washes, self-service bays, and high-pressure pre-wash applications. The high-foaming, phosphate-free and NTA-free formula at pH 13 rapidly dissolves insects, bird droppings, road film, environmental contamination, and rim soiling without requiring contact washing, making it ideal for non-touch high-pressure wash systems and high-volume operations.

Built-in corrosion inhibitors make it safe on sensitive surfaces including anodized aluminum, so it can be used on a wide range of vehicle types and wheel finishes without risk of damage. Also effective for removing copolymer coatings and wax films from paint surfaces as part of a preparation or stripping process. Highly concentrated formula delivers exceptional value per diluted litre for commercial operations.

If you are looking for the best concentrated alkaline pre-wash cleaner for commercial car washes, a Koch Chemie high-pH pre-soak for non-contact washing systems, or a professional foam pre-wash concentrate that removes heavy contamination before the main wash cycle, MSN Multi Star N is a trusted product in high-volume car wash operations worldwide. Available in 5L and 20L.
