Digital Ultrasonic Jewelry Cleaner by Hagerty

How it works:
As ultrasonic waves pass through the solution in the tank, they cause alternating high and low pressures in the solution working in all directions and dislodging dirt from all recesses and openings. The Hagerty Jewel Clean Concentrate formula contains no butyls, phosphates, bleach or ammonia. It is safe for use on all porous stones such as opals, choral, onyx and turquoise.
