Hello, An elementary question from a rank amateur: What is used
in an ultrasonic cleaner?
I picked up a little gadget at a garage sale that is labeled
’'Gem Sonic" It is made of blue plastic and holds about a cup
and a half. It purrs nicely and gets warm. I am wondering how
useful it is in a home lapidary shop? It did a good job of
cleaning up beads with liquid dishwashing soap, but did not get
metal marks off the carnelian beads where they had been wired.
My gut feeling is, that for general jewelry cleaning a little
ammonia added to the soapy water would probably work OK. Will
it work in a small shop? What kind of solutions do you folks
use? Thanks in Advance, Rose Alene McArthur
