Actually, I've found several ways to deal with Bullet Mold. Windex and some other glass cleaners seem to work quite well. Simple Green is also quite effective although probably the best (so far) has been (Krap, I forget the name of it).
I did find the overall best solution (pun?? Nah!!) was to shoot the bullets up before any mold could form. I mean, Moldy bullets just look so terrible. Everybody at the range will point and giggle. (I think thats what there pointing at). Then when you shoot a poor target, they all look atcha and comment how it's just got to be those moldy bullets.
There is no point in investing in a new mold. New mold is the same ugly color as old mold. In all actuality though, I'd just not get too worried about bullet mold. It'll all come off goin downa barrel anyway.
