How do you clean a fiberglass hull?
Use a specialized boat cleaning soap, and follow the instructions for mixing amounts into a bucket of water. Once your soap and water are mixed, wash your boat’s gelcoat surface with a long-handled soft brush or sponge, and rinse it off again thoroughly with fresh water to remove any excess grime, dust and debris.
What is the best thing to clean a boat with?
When dealing with plastic and glass in and around the boat console area, an all-purpose spray cleaner, or “Windex” will do the trick. I like to use a partially wet, soft sponge for the initial rub down, and then finish the job with a dry cloth.
