Yellowed seats
 

The sun deck on my boat has yellow brownish stains on it. I am looking for something to remove them especially on the white. I have tried magic eraser, soft scrub, toilet boll cleaner with bleach in it, straight bleach, carb cleaner, mineral sperits, and none of them completely got rid of the. I just bought the boat so I am not sure what the stains are from. Any suggestion would be great. Thanks Eric

With everything you have tried, I doubt they are ever going to come out. I had similar stains on my engine hatch vinyl and tried everything. I think they were actually coming from under the vinyl. I just had the vinyl redone on mine.

I'd agree with Griff, doubt they are coming out. Suprised the carb cleaner didn't disolve the vinyl.:eek:

The only thing I've tried that worked for red clay stains was Simple Green 1:1 with water. Scrub, rinse for a long time (it's strong stuff). It might be worth a last ditch effort.

Last resort, maybe in the summer try to expose it to the sun. I have the same issue. The more sun exposure the fainter they became.
