I have a K-98 mil surp gun that I just can’t seem to get the barrel clean. And I’ve been at it for several days. I first used 30 caliber brushes and they weren’t big enough. I got 8MM brushes and have already worn one of those out. I’m on my second brass brush and can tell it too is wearing out. The black crap is still coming out of this barrel. I’ve tried the foaming bore cleaners and letting it soak. When I patch that stuff, it looks like black goo. I was wondering if I used a 50-50 mix of diesel fuel and tranny fluid , filled the barrel and let it set a few days in my shop, if that would be a good idea. I hate using a brass brush this much on a barrel. Just trying to come up with a way to dissolve this stuff. Any ideas?
