An ultrasonic jewelry cleaner works by using cleaning fluid in a container to clean jewelry. A motor device creates ultrasonic waves which travel easily through the cleaning solution. These waves work to dislodge dirt and grime from the jewelry item in as little as 3 minutes. Longer may be required for large pieces or those with more dirt.

If a camera lens has the letters USM printed on it, it means UltraSonic Motor. This means that the motor is built into the body. These lenses tend to cost a little more than a lens without a USM.
