wtf will take out leaf stains!!!!!!! wifes uncle has a couple leaf stains on his interior, tried everthing to get them out to no avail..... any suggestions

Simple Green and fine steel wool.  Works on everything that I needed to get out.

Try Magic Erasers by Mr. Clean. Takes the stink off shit

Yeah, but will it get the "Brown Out"? 

The trick I have heard of is to put a sliced potato on it for a time, I know it works on rust, but no idea why. I had a customers boat come in that had an old rusty chain sitting on the rear jumpseat all winter, rusted the white vinyl to a nice orange, we tried the sliced potato on it sliced surface down and it was all but invisible in two days..

No clue what it did...(Thanks grandma!)

Never tried Magic Eraser stuff, but I use Bleche White, which is avaliable at any auto parts store, it's made for cleaning white walls on tires, but does a damn good job removing any stains from vinyl. its semi caustic, wear gloves and dont breathe the stuff tho.
