I had always felt there had to be a better way to clean brass. Well I was poking around on YouTube and came across a video where a guy was using a ice cream maker from wallyworld and lemishine. Well I was looking into trying that and came across a guy using the double drum rock tumbler from harbor freit. ($40) so I went that route. After experimenting here and there using the right ss. pins. I found that the pins are not really necessary. The lemi-shine and a drop of dawn is working wonders. Here are some 9mm wet tumbled for 20 minutes using only lemi-shine and dawn and water.
