This 20 oz ultrasonic cleaner is available on Amazon for $ 39.99, but it costs $ 20 when the 50% clip coupon is applied.

A similar ultrasonic cleaner to the one I recently posted (the coupon expired quickly), but from a different manufacturer, and for almost the same price after the coupon is applied.

The ultrasonic cleaner is intended for cleaning items like glasses, jewelry, retainers, rings, and other accessories. It has a 20 oz capacity and uses 42kHz ultrasonic waves to clean with tap water.
