I use a cheap Harbor Freight rock tumbler ($25 on sale). I cut up one of those green scrub pads after it is used up at the kitchen sink. I put a squirt of Dawn in the tumbler with water and cut up pads and about 100 pieces of brass. After tumbling a couple hours I dump into a colander rinse and dump onto a towel to dry. This works well for me and have been using it for 15 years now. No problems with the tumbler thus far.
