The ultrasonic cleaner is a microprocessor-controlled device that uses ultrasonic or high-frequency sound waves to clean the jewelry and other delicate items. Ultrasonic cleaning is based on the cavitation effect caused by high-frequency ultrasonic wave vibration signals in fluid. Microscopic bubbles that expand and rapidly collapse cause cavitation, which creates an effective cleaning action on the surface of the object being cleaned. Additionally, the bubbles are small enough to penetrate even microscopic crevices, cleaning them thoroughly and consistently.
