Acidic Boat Pre-Cleaner Koch Chemie Hull Precleaner acid (1 l)

Koch Chemie Hull Precleaner acid is a highly concentrated acidic pre-cleaner designed for thorough cleaning of boat surfaces. It is suitable for gelcoat, painted, and plastic surfaces, as well as stainless steel, making it a versatile choice for preparing hulls and decks for further treatment. Thanks to its combination of mild acids and surfactants, it gently yet effectively removes even stubborn deposits that commonly accumulate on boats.

One of the main advantages of this product is its ability to dissolve limescale deposits and remove rust stains, which are common problems on boats. This makes it ideal as the first step in a thorough cleaning process when regular washing is not enough and the surface needs to be prepared for subsequent polishing or protective treatment. Thanks to its high concentration, the product can be diluted according to the level of contamination, making it suitable for both regular maintenance and intensive cleaning of heavily contaminated surfaces.

Koch Chemie Hull Precleaner acid is an excellent choice for anyone looking to thoroughly prepare boat surfaces and achieve a clean foundation for further treatment. After thorough cleaning, the manufacturer recommends polishing and applying a protective coating to help prevent rapid recontamination. However, contact with sensitive materials, such as galvanized steel or aluminum surfaces, should be avoided.
