I tried the magic eraser on my Volvo's plastic molding. Current Volvos with non-painted molding have a textured, charcol-gray, colored molding. I got a little Meguiar's #9 on the moldings last weekend, and it started to show after I washed it this week. I tried the Magic Eraser on the molding and it seemed to work ok with a little elbow grease. I think the texture on the moldings makes a little more work out of it. You have to make sure to wipe down the moldings after you use the eraser because it will leave a white residue. Anybody else try the Magic Eraser on their black plastic moldings? I'm still searching for an easy way to clean stain from polish/wax.
