[QUOTE="Bullet bumper, post: 283573, member: 17844"] Thanks "tlk" I am having difficulty with the site it is treating me as a guest and I am registered . The cookies don't seem to be loading . Anyway the black staining on your patch that is soaked in naptha solvent is just mainly carbon residue from powder combustion. Most of the metalic copper / zinc has been dissolved into the ammonia bore cleaner (Sweets). Ammonia eats copper and zinc alloys so you should keep ammonia away from cartridge cases . It will clean them by dissolving some of the surface but it reacts with the copper zinc alloy to speed up age hardening of the brass. Adding cleaners like Brasso to case tumblers will cause some extra hardening of the cases. Weak acids are actually easier on brass as a cleaner because they react more with the tarnish and grime not as much with the copper / zinc alloy . Don't forget to wash and patch the chamber and the locking lug area also to make sure no bore cleaners or solvents are leaking down the loading ramp area into the bedding or following the barrel threads into the bedding. Dental pads , you know the circular cotton ones they jamb in your mouth , they are very good for cleaning the locking lug area. Just drill a hole through the very end of a piece of wooden dowl that just neatly fits the cotton pad in. Cut the lenght of the pad to just fit across the inside of the locking lug recess witha bit of jamb so it scrubs up any rubbish or solvent. [/QUOTE]
