I have that gray/green moss ,that you see on treebark, on my topside. very hard to scrub off. Anyone know an easyer way to remove it.

FYI I used (No scratch Comet with Bleach) to get things cleaned up. Others told me to use TileX or other bathroom cleaners with bleach ie softscrub things like that. Home depot and lowes sells a deck and fence wash that kills mold and is more outdoor safe than laundry bleach just mix it up in a pump sprayer and go to town. which you use will depend on how far gone the finish on your boat is

Hi - If it's REALLY bad and has stained things a bit there is a marine cleaner called On/Off that does a remarkable job. Be warned though, that this stuff is powerful and that while it won't damage your boat's finish, it can hurt you if you don't follow the safe handling precautions (especially ensuring adequate ventilation). This should handle any stains resulting from moss and mold as it makes fairly short work of rust stains too.
