Scouring brushes or wire brushes will scratch the fiberglass, so you want to use a Scotch Brite nylon brush, soft cloth, or sponge for wiping the boat and scrubbing stubborn stains. If needed, pour a gallon of warm water into a bucket to use to rinse off the cleaner.
You can also use additional natural ingredients for specific polishing and shining. For cleaning and polishing chrome, a little bit of apple cider vinegar and baby oil will have it shining. Hydrogen peroxide also makes a great bleach alternative for tough spots.
It’s also essential to wear protective gear while cleaning, as fiberglass dust is dangerous to inhale. Wear gloves, safety glasses, and a mask to stay safe while cleaning the boat.
With these homemade fiberglass boat cleaner recipes and a little bit of elbow grease, your surfaces will sparkle.
