Marine Hull PreCleaner Alkaline

Hull PreCleaner is a highly concentrated, phosphate-free alkaline cleaner designed specifically for the first stage of boat cleaning. Its powerful formula quickly breaks down heavy buildup such as bird and duck droppings, environmental grime, and weather-related soiling, making it ideal for preparing the hull and deck for a deeper clean.

The strong pre-wash action helps loosen stubborn contamination before the main wash, while providing high material compatibility with sensitive components such as anodized aluminum.

How to use: Dilute 1:20 to 1:60 with water, depending on the level of soiling. Apply to the surface and allow to work for a maximum of 5 minutes. If needed, agitate with an Allrounder Scrubber. Rinse thoroughly with water and a sponge.

Do not use on: Galvanized steel, sensitive aluminum surfaces, or real wood. Only use on washable surfaces.

Check material compatibility before use. Do not use on hot surfaces or allow the product to dry.
