These work fantastic, and I got a better deal on Amazon than I can get them locally.  For anyone who hasn't used them, please realize that they are mildly abrasive (I think they are probably the equivalent of using a baking soda paste), and they gradually disintegrate (looks like they are shrinking) during use.  They can be used multiple times for small jobs, just keep them dry between uses.  I also recommend wiping cleaned areas with a damp cloth to remove the film left behind from the Magic Eraser.
