Ultrasonic Cleaner?

Does the Jewelry department have an ultrasonic cleaner? Looking to clean up a few small jewelry items.

They do, however I am unsure as to its operational status at this time.

Do we know if this has been fixed yet? Would like to clean a class ring, ideally with an ultrasonic cleaner. Any tips on how to do so without harming the gold would be appreciated too. Thanks,

Yes, it was never broken and ready to use. Please make sure you turn off the heater after using it and clean up any spills/splashes. As for tips, be careful if the ring has stones! Otherwise, this is a decent video overview for reference.

You will also want to use the steam cleaner after the ultrasonic cleaner. It has to be turned on for a while (15 minutes?) to build up steam.
