Ultrasonic cleaner: A machine that cleans
jewelry by using a fluid that is vibrated
at 20,000 cycles per second. When the vibration speed rises above the
ultrasonic frequency level, bubbles explode and generate strong power,
cleaning the surfaces and cavities of hard-to-clean objects. Ultrasonic
cleaning does not scratch the surface or harm objects like many chemical or
abrasive cleansers.
