Marine Hull PreCleaner Acid

Hull PreCleaner Acid is a concentrated acidic cleaner designed for pre-washing gelcoat, painted, and plastic surfaces on boats. Its blend of mild acids and surfactants is especially effective at breaking down limescale, mineral deposits, and rust stains while providing a thorough clean.

Ideal for hulls and decks, it helps remove the buildup that can be difficult to tackle with a standard boat wash, leaving the surface clean and refreshed before the next step of the cleaning process.

How to use: Depending on the level of soiling, dilute 1:10 with water. For heavy soiling, the product can be used undiluted. Apply with an acid-resistant pressure sprayer and allow to work for 3–5 minutes. If needed, agitate with an Interior Allrounder Scrubber. Rinse thoroughly with water and a sponge.

Do not use on: Galvanized steel, aluminum, or real wood. Only use on washable surfaces. Do not allow the product to dry.

Check suitability and material compatibility before use. Do not use on hot surfaces. Wear safety glasses during application.
