A big YAY for Magic Erasers in my book, they really are wonderful. Now they've come out with various types, heavy-duty, mag & wheel, etc.. I used a mag & wheel one but honestly I couldn't tell the difference between it and the regular or heavy duty which also are both no difference that I could tell. The nice thing with them is you really don't have to rub very hard either and they clean out the scratches and embedded scuffs easily.
Jeff I'll email you shortly...btw I gave it a test run last night and it seems that the pile adjustment is out of whack as well. When you pull back on the handle the brush end seems to drop right down and drag. Hopefully nothing.. I haven't taken one apart before.
