I've cleaned out a couple of art stores of maleable eraser - GREAT stuff and so easy to use
On cleaning copper, you'll find that Bartenders Helper is awesome stuff. Never used it on a pot, but the wife uses it on our copper kitchen pots all the time and they come out looking new each time
got a Dice pot coming from a friend, so gonna play with that for awhile. The wife INSISTS I cannot use LN2 in my office, I can only play with it in the basement, and I can't play with it there till my daughter moves out.. which will hopefully be within the next couple of months... hopefully being the key word :(
Oh well...
