Alkaline Boat Pre-Cleaner Koch Chemie Hull Precleaner alkaline (1 l)

Koch Chemie Hull Precleaner alkaline is a highly concentrated, phosphate-free alkaline pre-cleaner designed for pre-washing boat decks and hulls. It is formulated for thorough pre-cleaning of gelcoat, painted, and plastic surfaces, helping to quickly loosen even stubborn contaminants before further washing, polishing, or protective treatment. This makes it an ideal choice for anyone looking to prepare their boat for further care thoroughly and with minimal effort.

One of the main advantages of this pre-cleaner is its combination of high-quality complexing agents and special surfactants, which effectively tackle even challenging contamination. According to the manufacturer, it efficiently dissolves bird and duck droppings, environmental deposits, and dirt caused by weather exposure. This makes it an excellent first step when cleaning heavily contaminated boat surfaces where regular rinsing or a milder shampoo is not sufficient.

Koch Chemie Hull Precleaner alkaline is particularly useful for boat owners who want to ensure their hulls and decks are perfectly prepared for subsequent polishing and protection. 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, aluminum surfaces, or natural wood, should be avoided.
