For the other parts, I use whatever is handy. Recently started using Ballistol, but like CLP Breakfree a lot. Also on the bench/in the drawer are RemOil, Olio Beretta, Rusty Duck, 3-in-1, Singer sewing machine oil, Tetra (mostly for handguns), and other stuff I don't even remember. I guess I need to use up some of this stuff just to get rid of the odd containers.
