    Dried on cosmoline stain.

    My latest m1 acquisition had cosmoline stains all over the metal that looked like rust stains.
    For lack of a solvent at hand I grabbed the supreme commanders nail polish remover and some four ought steel wool and rubbed lightly and the stains came right off the parkeriing underneath was perfect. Just thought I would pass it along just put the bottle back.

    If you look at the ingredients of nail polish remover it is acetone or ethyl acetate and isopropyl alcohol, the same solvents you would use to remove cosmolline.
    It's a great marketing scheme to make women pay the same price for a tiny fancy 2 oz bottle of acetone as men do for a quart of acetone in a hardware store.
