bling bling http://www.autobarn.net/magiceraser.html picked up some of these at WalMart the other day, and tried 'em out yesterday. Hot damn, they work great. One 'eraser' did all 4 of my wheels that were COATED with brakedust from 2 different trackdays. I was quite impressed. I think it -may- have been the coat of WheelWax that I had on there that helped to repel the brakedust, but either way, i fully recommend these Magic Erasers. Not sure what the difference is between the normal ones and these "wheel & tire" ones ... they look/feel/smell exactly like the normal household ones. two thumbs up.
