Hull PreCleaner Acid

Koch-Chemie Hull PreCleaner Acid — a highly concentrated acidic pre-cleaner for boat hulls and decks. A blend of mild acids and surfactants dissolves limescale, mineral deposits and rust stains while staying gentle on the surface. Where the alkaline pre-cleaner handles organic dirt, this is the one for the hard, chalky deposits that water leaves behind.

• Concentrated acidic boat pre-wash
• Dissolves limescale, mineral deposits and rust stains
• Dilute 1:10, or use undiluted on heavy deposits
• For gelcoat, boat paint, plastic and stainless steel
• Pairs with Hull PreCleaner Alkaline for a complete pre-wash

Dilute 1:10 for normal soiling or use neat on stubborn deposits. Apply with an acid-resistant pump sprayer or sponge, allow up to 5 minutes to react, agitate if required, then rinse off thoroughly. Available in 1L and 10L.

Read this before you use it. Always use an acid-resistant sprayer. Never let it dry on the surface and never apply to hot surfaces. Check suitability and compatibility before use, and wear safety glasses and gloves.
