How to Clean Your Fiberglass Boat Fast & Easy

Quick Answer

Rinse the hull with fresh water first to remove loose dirt and salt. Apply a dedicated fiberglass boat cleaner or a mix of boat soap and water, then scrub with a soft brush or microfiber mitt using circular motions. Work from top to bottom. Rinse thoroughly and dry with a chamois to prevent water spots. For stubborn stains, use a fiberglass oxidation remover. Finish with a marine wax or polish to protect the gel coat and keep the surface looking sharp longer.
