+1 on the Stainless tumbling media in a "Thumbler's Tumbler." I've run a few batches where the container was more than 3/4 full of .223 brass; read that as OVER FILLED. Everything comes out lookin' like new. Just add enough water to cover the brass, the SS media, a good squirt of DAWN dish soap, a heaping tablespoon of a product called LEMME SHINE; all carefully measured by eye. (I'm blind in one eye and can't out of the other) Bolt the cover on and let it run for a few hours. The Brass will be as clean as you could possibly want it, inside and out.
One word of caution from personal experience, use COLD water! First time out I used very WARM water. I was going to get'em real clean!
Several hours later when I tried to get the lid off and things had cooled off, the vacuum created really held that cover on tight. Had to do a bit of carefull prying to break the seal without damaging the unit.
