Thread: Tumbler or Sonic cleaner

If the pins are a wet cleaner process, it's sort of (depending on the fluid used) a combo of ultrasonic and vibratory. I've heard of people putting tiny ceramic beads in the ultrasonic fluid, but my personal opinion on that is more hassle than it's worth. The point of ultrasonic is that if it's tuned correctly the cavitation bubbles imploding will knock everything off that needs to be knocked off the part being cleaned. The difference is 60seconds of cleaning vs not clean in 10 minutes if the cleaner is properly tuned. Ultrasonic is the fastest of all methods, which is why it gets the cases so clean.
