School me on sonic cleaners...specifically frankford arsenal

If I had to do it again, I'd pay the extra money for the frequency sweep option. Then you never need to stir the brass around to get it all clean. At least, that's the theory-- I haven't actually tried one, but it should work, moving the interference nodes around.

Until mine tears up though, I guess I'll just keep stirring.

I got talked out of sonic cleaning and into tumbling with steel pins.....best advice I ever took. Simple and results are awesome.
