Koch Chemie Hull Precleaner acid

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 parts as well as stainless steel, making it a very versatile choice for preparing the hull and deck before further care. Thanks to a combination of mild acids and surfactants, it can gently yet very effectively remove even more stubborn deposits that commonly form on boats.

A major advantage of this product is its ability to dissolve limescale deposits and remove rust stains, which are a very common problem on boats. That is why it is ideal as a first step for more thorough cleaning, when ordinary washing is not enough and the surface needs to be prepared for subsequent polishing or sealing. Due to its high concentration, the product can be diluted according to the level of soiling, making it suitable both for regular maintenance and for intensive cleaning of heavily affected areas.

Koch Chemie Hull PreCleaner acid will be appreciated by anyone who wants to prepare the boat surface very carefully and achieve a clean base for further treatment. After thorough cleaning, the manufacturer recommends sealing the surface by polishing and applying a preservative to limit rapid re-soiling. When using, avoid sensitive materials such as galvanized steels or aluminum surfaces.
