Well I am not sure just alcohol will clean off the nail polish. The nail polish I believe is a little thinner so easier to get into small places. I have only cleaned it off in small places but the acetone worked real well. I suppose you could actually just dip the whole card in a pan of acetone and it would come off. I am not to sure about that though. As for the electrical tape I have that also. Got some on my hand and it was a real pain getting it off so decided not to use it.
