Koch Chemie Hull Precleaner alkaline
Koch Chemie Hull PreCleaner alkaline is a highly concentrated, phosphate-free alkaline product intended for pre-washing the boat's deck and hull. It is designed for thorough pre-cleaning of gelcoat, painted and plastic surfaces, where it helps to quickly loosen even stubborn dirt before further washing, polishing or sealing. For this reason it is an ideal choice for anyone who wants to prepare their boat for further care thoroughly and without unnecessary effort.
A major advantage of this pre-cleaner is the combination of high-quality chelating agents and special surfactants that cope with more demanding contamination. The manufacturer states it effectively dissolves bird and duck droppings, deposits from the surrounding environment and dirt caused by weather conditions. That is why it is suitable as a powerful first step when washing more heavily soiled boat surfaces where normal rinsing or a milder shampoo is not sufficient.
Koch Chemie Hull PreCleaner alkaline will be especially appreciated by boat owners who want the hull and deck perfectly prepared before subsequent polishing and protection. After thorough cleaning, the manufacturer recommends sealing the surface by polishing and applying a preservative to reduce the risk of rapid re-soiling. When using, avoid sensitive materials such as galvanized steels, aluminum surfaces or real wood.
