Get a tumbler. Add media. throw in brass. Secure lid. Plug in tumbler and turn on. Go have beer. When you come back in a few hours, it should be clean and shiney. Now you can either pick the brass out (small loads) or dump the tumbler's contents into a separator. Wear a mask, it's dusty. other then that, I don't see why you should worry, you'll suck more crap into your lungs on the average street corner. - dan
