So this might not be news to anyone, But I tryed it last night.
My corncob media was getting to the end of its life span. The cases were coming out more and more dull and dusty. So I had an idea, I usually use brasso to polish my collectable ammo and artillery shells. I put the media back in the tumbler, put about 1/3 of the can of brasso in the media along with about 60 peices of brass(7.62x54, .45acp, .308, and .223). Left it on over night, Unlugged it this morning and took a look. With a slight rub from a rag it is by far the most shiny brass I'v ever got back from the tumbler.
