I'd heard of the ultrasonic cleaners, but have never seen what one can do. I see HF has them for $90. I just may have to get one. The 2G rebuild video I saw mentioned cleaning the 2G with an ultrasonic cleaner.
The finish on this 2G is gone. I'm fine with that. I'm not a bling person anyhow.
Do not judge the capability of good ultrasonic cleaners by one you can buy for $90.
Probably could get about the same results as the $90 cleaner by boiling the parts in a 3 pound coffee can!
Ours was just a shade under 5k. And the best 5k I ever spent on tools.
