An ultrasonic cleaner relies on a process called cavitation to gently and thoroughly clean the surface of your parts. An ultrasonic transducer attached to the cleaning tank transmits high frequency(30kHz) sounds into the cleaning solution. During the low pressurestage of each sound wave tiny bubbles form and grow. During the high pressure stage these bubbles collapse, removing dirt, rust and other contaminants. This cleaning action can reach any exposed surface, even into deep crevices.
