Koch Chemie HAC Hull Precleaner Acid 10 L

Koch Chemie HAC Hull Precleaner Acid is a professional acidic cleaning concentrate for boat hulls, yachts and other marine surfaces. The acidic formula penetrates deep into lime scale, rust and mineral deposits, dissolving what alkaline products cannot reach. Standard shampoos and alkaline cleaners do not effectively remove this type of marine build-up; the acidic pH breaks the bond with the surface and allows thorough rinsing. The 10 L can is intended for marinas, shipyards and professional cleaning services maintaining large surfaces on a structural basis. The product is tested on gelcoat, painted marine surfaces, plastic and stainless steel. Personal protective equipment is mandatory during use.
