Anybody have any recommendations on how to remove mild surface corrosion without damaging the original finish of the pistol? Just a couple of spots on my new (old) Bankers Special I would like to clean up.
Never tried that particular method before; but have seen the results and many destroyed finishes from owners going to town with steel wool. The trouble with steel wool is it is hard enough to remove the bluing surrounding the pitting. The old tried and true method to remove rust on blued firearms is using a good penetrating oil and an old copper penny (not a new penny which is copper plated zinc). Copper is hard enough to break the rust pitting from the surface but soft enough that it will not scratch or remove finish from the blued surface. It's as simple as allowing the penetrating oil to soak in (Kroil is the best) and then using the copper penny to scrap the surface. Once you see the oil turn brown, wipe it away and apply fresh oil and continue to scrape the surface. Once all the rust is removed the surface will feel smooth as you scrape and only fine copper residue will be left in the pores of the surface. A gentle wipe with a good wax, I use Flitz Waxx (not polish) removes the copper residue from the pores of the metal and all the rust is removed.Blue Wonder and 0000 Steel wool. You will be amazed.
