Ultrasonic Cleaning is a unique phenomenon. Millions of tiny bubbles are created when ultrasonic sound is passed through liquid. It is these tiny bubbles combined with a huge pressure that creates incredible cleaning results.
Use Ultrasonics for cleaning necklaces, earrings, rings, waterproof watches, coins, badges etc
NOTE If in doubt we recommend purchasing the watch / earring stand to keep the non-waterproof part out of the water
