More or less this was just an excuse to buy another tool. I have 2 entire cars worth of these little guys to clean so I wanted to see what I could do. They are not horrible dirty or rusted and I soaked them in wd-40 first. I almost got them as clean as I would of liked. I think a bag of 20 of these little guys is just a few bucks but its fun to play around and learn something. This picture is what they looked like before I put them in the tumbler.
