what is the best cleaning agent for fiberglass?

Answer 1

The best is Y-10 Jelly Fiberglass cleaner. It is non abrasive, and requires no scrubbing. You apply and rinse. Find it at your local marine store. It is the best that I have found.

Answer 2

I suppose it depends on what you are trying to clean off, but for regular fiberglass maintainance I wash it with dish soap and water. I also use Meguir's cleaner wax and take it off with a buffer. Best stuff I've found in 20 years of boating, and you can get it relatively inexpensive at any auto store. If you trailer your boat (like I do) and get tar and bugs on it, I use Theford premium RV Black Streak and Bug Remover. Takes off tar, shoe marks, and bugs and is gelcoat safe. (and it's only 4.99 for a 32 oz. bottle) I would caution against any cleaners that have acid (like toilet bowl cleaner), or you can damage your gel coat. If there is oxidation, you can use polishing compound with a buffer before you wax. If you want other information, you can also check this web site. They also have tips for almost all boat maintenance also. Good Luck http://www.boatus.com/boattech/casey/01.htm

Answer 3

tidy bowl bathroom cleaner. we have used this for years.
wet the boat pour this over the fiberglass and rub with a sponge
rinse well and let dry. it removes water stain build up, its cheaper than those expensive boat cleaners, and leaves the boat with a shine. there is just enough acidic cleaner in the tidy bowl that it cuts through the stains on the boat.
