Stain out of white boat???

we always have had excellent results out of starbrite hull cleaner. pour it into a sray bottle and spray it onto the stain then just rinse off. for some stains it might take rubbing it on with a sponge. youll need a pair of rubber gloves and be sure not to let the spray blow back into your eyes.

Black Streak remover by 3M will pretty much do the job. Also ive had good luck with grease lightning on alot of stains on the boat. Just a food for the thought, try a bounce fabris softner sheet to wipe the stains with. Spray stain with streak remover or grease lightning and dampen softner and rub, should do you good.
