A friend of mine picked up a few rounds of 50 BMG for display purposes and gave one to me, but it has a few imperfections, I'd like to lightly polish it to bring back the luster of new brass and copper, but I'm not sure of how to go about it, or what to use. I don't want to get crazy with it, it isn't a museum piece.

Anyway, I DO NOT want to de-mil the round, I feel that it would be a waste, what do you guys suggest?
