Now that you have many homemade boat cleaners to choose from, you need to know how to clean fiberglass boat surfaces. After applying the soap, it is essential to use the right cleaning tools to ensure that you not only get the surface clean but that you do not damage it in the process.
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.
