But, I'd be careful with acetone use this time of year in a closed up home.
Good point and not only that, but not having tried it, I'm not sure of any problems one might have with errosion or burning or even taking some of the bluing off. So unless someone has already tested this home brew, I'd stick with what has been proven. I once have a stuck breech plug in an MK-85 and when it finally came loose, there was quite a buid up of rust on both make and female threads. I'm lucky to get it loose. .....
Be Safe !!!
