Our new ultrasonic cleaner generates 42,000Hz of ultrasonic waves letting you clearly see the dirt separate off into the water. Powered by quiet, solid state technology, tiny bubbles are generated that constantly implode causing shockwaves to separate the dirt from the surface of any item in the water. With five cycles to choose from, just fill the stainless steel tank with water, place the item to be cleaned in the tank and press start. Works on jewelry such as rings, necklaces, and earrings as well as glasses, dentures, pen nibs, coins and metal utensils. Includes a basket to hold small items and a watch stand for cleaning watches.
