The other day, a coworker said that his dad would add some powdered cleaner to his tumbler to help clean his brass. When I got home, I looked around the house, and found some comet. It wasn't the brand that I was told about but I was going to try it anyhow. My walnut media was to the point I was about to replace it, so that was as good a time as any. I had been trying to clean up some dirty brass with no luck. I knew it would clean up, cause I had taken neverdull to it with good results, but it took time.

The Comet worked good. The brass cleaned up a lot better. I think I will still have to hit the brass with neverdull or let it go longer in the tumbler, but it looks a lot better.
