    Rust in my gun - how to get out?

    Going to be picking up a PSL I recently traded for, but it's got a bit of rust in it from corrosive ammo.

    So - just a question for those who may have had to deal with rust in the barrels and action in guns that shoot corrosive ammo: What should be my first step to clear out the rust in the barrel and other parts of the gun?

    From what I understand, doing the normal cleaning procedure with solvents and oils won't work because the corrosive salts are still present and still will continue to attract moisture resulting in more rust. My plan was to take an old bore brush and a brass-bristled toothbrush, a small tub of warm, soapy water, and clean the bore, action, and any other part showing rust and rust dust with the soapy dishwater (I hear Dawn brand is particularly good at cleaning stuff to squeaky-clean condition), then drying off with towels, dry patches in the bore, and even a hair dryer to get into the parts I can't reach with towels or patches. Then, spray the gun liberally with WD-40 (after all, it advertises itself as a "water displacer - #40"), wipe down with patches again, then clean as normal with my personal solution of 50/50 Hoppe's #9 and Kroil, then oil and then grease on the sliding surfaces of the bolt carrier/piston assembly.

    Is that a good plan, or am I missing anything?

      Shoot some rounds through it, and then give it a good cleaning. You can clean it for days and it will still have rust. Shooting it will knock the rust out.

        If you've got the Kroil already, I'd give the barrel a good soak with that first. It gets into the tiniest pores as you know.

        After the soapy bath, try blasting the action and tight spots with an air-compressor. After it's dry, I'd re-Kroil the whole thing.

        For lube try Phil's Tenacious Oil, comes in a green bottle, found at high-end bicycle shops. I use it on my autoloaders.

        Good luck.

          Try using Sweets 7.62 gun cleaner after you use some warm soapy water and compressed air on your rust. the sweets is very noxious, so use a mask or well ventilated work space.
