How To Clean A Boat Hull

Quick Answer

Rinse the hull with fresh water first to remove loose debris. Apply a dedicated hull cleaner to the surface and scrub with a stiff brush, working in sections from bow to stern. For stubborn waterline stains and oxidation, use a marine-grade compound or hull cleaner formulated for your hull material, fiberglass or aluminum. Rinse thoroughly and dry to prevent water spots. Finish with a coat of marine wax to protect the surface and make future cleaning easier.
