OK i need a little help guys. I have a minty type 2 Superman that someone must have left on a doll stand for a long time. It has some brown staining on it's front and on the vinyl yellow belt. I know i have heard oxy clean is good for the fabric but how do i get the staining off the belt. Other than this he is nice and blue and the cape is nice and crisp? I'll get a pic up in a minute. Any help is appreciated.
