I lost the oil on my port side Trim Tab and it covered the back of the hull with a black stain. Any suggestions on what will remove this? I tried Simple Green and Slimy Grimy so far, and neither touched it.

try Soft Scrub or a mild polishing compound. that should do the trick

Thanx Dave, I'll give it a try this week!

Glass Dave, you're a genious! My transom looks good as new. Now if I can just keep those Trim Tabs from blowing fluid all over, I will be all set. Thanks again!!!!!!!!!

tell ya what. i also use soft scrub on my cockpit vinyl and it takes out the toughest stains. keeps it lookin bright white and works on the rest of the boat too.

Does it take out ball point pen on white vinyl? Or is there something better? I've tried Knight's Marine 9 cleaner and GoJo, plus Goo Gone and the line is still there, although lighter.

Check out Mr Clean erasers--really magic and cheap. They clean white vinyl to as new--without any visible damage.

I have had good sucess with Superclean by Castrol in removing all kinds of petroleum spills and stains. Be sure to read and follow the directions though, as it is powerful stuff and can cause residual damage if used improperly.
