- A few options exist when cleaning a fiberglass boat: mild soap, white vinegar, or a cleaner made for fiberglass. Rinse thoroughly after to avoid streaks.
- Better, safer options exist like non-stick cleaners.
- Products to clean fiberglass boats include Star Brite Fiberglass Stain Remover. Its gel-like form works on vertical and horizontal surfaces, clinging to where it’s sprayed.
- An easy first step is rinsing with warm fresh water then using a boat soap.
- Fiberglass boat owners should avoid beaching boats. Sand is abrasive, scratching the gelcoat, allowing water invasion and antifouling coating removal.
- Gas tanks should never be completely filled because fuel expands when warmed, needing room.
- Fiberglass cleaners work by penetrating deep, using non-abrasive formulas that are tough on stains yet gentle.
- Apply a protective coating like boat wax when done. It blocks stains and wear while easing future cleaning. Removing old wax helps new wax adhere too.
