How to Clean Fiberglass Boats
The first rule in caring for your fiberglass boat is to clean it often. The second rule is to clean from top to bottom. There are many boat cleaning products designed for specific surfaces. Using a product meant for one surface on another surface can sometimes cause damage. Always try a gentle cleaner first, and, for tough jobs, a biodegradable degreaser. Here are a few tips on cleaning a fiberglass boat.
Things You Will Need
- Use caution if you clean your boat with a sponge or mop. Grit that's collected in a sponge or mop may scratch your boat. The flexible bristles of nylon brushes will not grind foreign matter into the surface of your boat.
- Do not use dry sandpaper to remove stubborn stains. Dry sandpaper is very abrasive and may scratch your boat. Wet your sandpaper prior to use.
