My new AK had a little white fuzz (like battery terminal corrosion) around one of the rivets. It came right off but I want to neutralize this stuff so the bleed out and corrosion does not continue. I have a couple of air rifles that have the same thing going on where the barrel goes into the breech block and I'd like to take care of them as well. I've read that you should clean well, submerge in white vinegar for a while, rinse and then oil. Anybody done this? If so how did it work out for you? I see that Brownells has stuff to do this but if I can save the 40 bucks and do it with more common materials, I'd like to try that first.
