Hull PreCleaner Alkaline

Koch-Chemie Hull PreCleaner Alkaline — a highly concentrated, phosphate-free alkaline pre-cleaner for boat hulls and decks. It quickly breaks down bird droppings, environmental grime, grease and the weathered film that builds up over a season, so the wash that follows is fast and safe. This is the first step in the Koch-Chemie Marine system, and the one that makes everything after it easier.

• Highly concentrated alkaline boat pre-wash — phosphate-free
• Removes bird droppings, grease and environmental dirt fast
• Dilutes 1:20 to 1:60 depending on soiling
• For gelcoat, boat paint, PVC and synthetic teak decking
• Ideal prep before Boat Wash, polishing or sealing

Dilute to suit the level of soiling and apply with a pump sprayer or sponge. Allow up to 5 minutes to react, agitate with a brush where needed, then rinse off thoroughly. Available in 1L and 10L.
