Today I run a clean patch and it comes out brown and green. Scrubbed it again with Birchwood Case bore scrubber this morning. And again this afternoon. This thing isn't getting any cleaner. It's getting dirtier! It is the dirtiest barrel I've ever seen.

Got and good home brew cleaning methods that won't wear out my arm and cleaning rods?

Shooter's Choice Bore Clearer is the strongest bore cleaner I've ever come across. With the muzzle side tilted down, put a thoroughly soaked patch of it through from the chamber end, and just let it soak for twenty minutes. Then scrub it, then patches. Repeat as needed.

Neat old Mauser.
