Well, the challenge has been put to me. I keep quoting great
ideas I read on the Orchid list and now my teacher and classmates
have posed a question to me to be put on the list (I guess as a
A classmate has a silver ring with a glass or citrine faceted
stone bezel set. You can see soap gunk or something underneath
the ring. Will the ultrasonic cleaning get that stuff out from
under the stone? How long should they leave it in the ultrasonic
(they only put it in there 3-4 minutes from what I saw). Should
they add ammonia to the water? Heating will have to be hot water
out of the tap, we're limited in that area.
OK guys, start brainstorming. Let's show 'em.
