Are you a boating enthusiast? Do you own a boat? If you answered “Yes!” to either question, you probably clean your boat’s hull at least once a year.

Our powerful hull cleaner, Drydock Strong, is the answer! Drydock strong is the ultimate treatment for restoring your boat hull to its original condition. It’s unique synergistic blend of acids, metal inhibitors, detergents and emulsifiers are designed to effortlessly clean and embellish your boat.

It will bring back the glow to your boat by removing silt, rust stains, oxidation, algae, slime, mould, pollution, etc., without damaging fibreglass, painted or metal hulls. Our cleaner is also safe for gelcoat and antifouling paint.
