spyder stains

have some real heavy spyder stain on my fiberglass..what works the best to remove

[Landlocked]

I have way too much experience with this. I wash the deck with some kind of boat wash, then let most of the water run off. Go back with Clorox Cleanup in a spray bottle and squirt the spots. Frequently I'll use a deck brush to spread the Clorox so it covers all the spots. Then leave it alone for 5 - 10 minutes and the spots disappear. Finally I run lots of water on the deck to wash the Clorox away.
I'm sure this is hard on wax, but generally these spots are on non skid where there isn't any wax.

If you're going to use bleach you will need to wax afterwards. If you have non-skid, try woody wax. Another less harsh alternative is simple green, with an erasure sponge. You can also try a cleaner/wax. If all else fails, a light compound with a wax afterward.
