Do Ultrasonic Stain Removers Work?
My dad uses an ultrasonic cleaner on his art pieces (he has a lot of tiny delicate glass stuff) but it’s a somewhat different system that involves putting the pieces in a sort of vibrating box, not using a wand. If you google for ultrasonic jewelry cleaner you’ll see what I mean. So the *idea* behind the ultrasonic cleaners is probably sound, but who knows if the wand design works well.
