Just watched an interesting video where Mark Novak boiled a disassembled revolver and a rifle to stop minor rust. He followed up with a carding wheel and or cleaned steel wool, then a soak in kerosene.
Curious if any of you have gone down this rabbit hole with an older firearm that you do not intend to re blue.

I used to only shoot shotguns and rimfires, then I made the mistake of getting a subscription to handloader.......
