Ultra Sonic cleaner

I run mine with just hot water and a little dish soap, five-minute cycles, and it gets the job done. Barrel parts come out cleaner than I expected.

Be cautious on the amount of time and how powerful the transducer is set. I ran into "cavitational pitting" because the pellets were left in too long under a high setting. Ruined the batch that i was cleaning. Just a heads up. I stopped using mine.
