Here's something I've been wondering for a while:
I see several sites recommending Vaseline or butter for removing stains from vinyl doll parts (like Barbie heads), but I keep hearing how bad grease and oil is for dolls - does anyone know how safe this is? What are the risks - long-term degradation of the vinyl? I'm no good at chemistry...
Two examples:

I've tried the vaseline method on an old Barbie head that was badly stained from blue hair dye. Basically I covered the face in vaseline and left in the sun for a few weeks, reapplying now and then. I didn't have the patience to stick it out, but it did lighten the stains considerably.
