This is the ultrasonic jewelry cleaner that has the features of a commercial model yet the compact size of a personal model. It uses solution and 40,000 Hz of ultrasonic sound waves to remove lotion, hairspray, grease, oil, and dirt from jewelry. It’s powerful enough to burrow deep into stone and setting crevices, yet gentle enough to handle fine jewelry. It has an elongated tank that allows the device to also clean eyeglasses, make up brushes, and other small items. With an integrated beaker, touch-sensing control panel, and a built-in cooling fan. AC plug. 5 1/2" H x 8 1/2" W x 5 3/4" D.
