I remember a thread BUT cant find it, what are you guys using to get brown stains off your boat? These are not exhust stains but more a discoloration on the back of the boat, thanks for he help!

I thought that's what FUTURE son-in-laws were for?

I'd like to know too. I've used the Zep Citrus Cleaner on the exhaust scum on the transom with great success, but that or hand rubbing compound won't touch this stain I've got on the hullside and transom area.

Slimy Grimy. The trick is to mix it with HOT water though.

Mary-Kate onn/off hull cleaner. I have been using it for years. By far the best I've ever tested. Good luck!

slimy grimy is the best they now make it in a spray bottle, spray it on and your hull will turn back to white within minutes

Where can you buy it?

I found a new product this year called Rid-O-Rust. It works great and is only about 10.00 a gallon. Go to www. proproducts.com to find a nearby distributor. They are in Ft. Wayne In. Hope that helps

try FSR its a blue gel, fiberglass stain remover, i get it at Marine max, it will just melt the yellowish brown stains right off.
