White vinegar works perfectly as both a cleaner and disinfectant. The vinegar will also dry clear, leaving no streaks or residue behind. In a spray bottle, combine equal parts of water and white vinegar. Spray the solution onto the acrylic or fiberglass surface, then wipe clean with a dry cloth or sponge.
Rubbing alcohol also has a similar effect, working as both a cleaner and disinfectant. In a spray bottle, mix a more diluted solution by adding 2 cups of water and 1 cup of rubbing alcohol. Spray onto the surface of the acrylic or fiberglass, then wipe clean with a dry cloth or sponge.
Baking Soda and Lemon Juice
These two ingredients work to clean and deodorize the surface of both acrylic and fiberglass. In a spray bottle, mix 2 cups of water, 1/2 cup of lemon juice and 1/2 cup of baking soda. Place the lid on the bottle and shake to combine the ingredients. Spray onto the surfaces, then wipe clean with a sponge or cloth.
