Anyone use an ultrasonic cleaner? As a tree surgeon I have lots of wee gadgets that would benefit from cleaning now and again, many have moving parts like caribiners, and chainsaw parts. I would quite like a cleaning device that would double up, cleaning brass and other things. Medium cleaners won't work for caribiners I would think as the parts will clog up with medium. But I don't want to splash out on something that won't clean brass.
So do they work on brass?
