Yes, when Elliott says a little acetone, he really really means a little acetone.

Apply very little.

Pure acetone will melt ABS, although it takes quite a while for it to do so (plus, polish remover is usually only 1-2 thirds acetone). It'll definitely remove those marks, but if you're not careful, it'll remove some paint decals from your blaster as well if you accidentally get some on there too. Maybe put some remover on a Q-Tip and rubbing it in the space between the rails. Just don't put the Q-Tip in your ear after. Anyway, Q-Tips were only meant for the outside of the ears, not the insides. Don't do either if it has nail polish remover on it.

Also I advise against drinking the stuff.
