What are your methods for cleaning your brass? I read that walnut media can be bought much cheaper at pet stores than at gun shops. The pet stores sell it for bird cages and other caged critters. I read that some are using stainless pins of some kind and that the medium last a long time unlike some corn cob or walnut media. Some are using white rice for the media. Some are using Nu Finish wax and fabric softener added into the media to absorb the dust and dirt from the media and also to keep down the static electricity. Anyway I thought it would be interesting to see what you are doing and using to clean your brass.
