Ultrasonic Jewellery Cleaners

Ultrasonic cleaners have dropped to prices where most households could easily afford to own one.
How do they work?

Ultrasonic cleaners use high frequency sound waves to agitate a solution, quite often tap water. This creates thousands of tiny bubbles that collapse and release an enormous amount of energy. As these bubbles are so small the force they place on the items in the solution is only enough to remove surface contaminants such as dirt, grease, fungus, polishing compounds and oils.

To help reduce surface tension in a water solution a small amount of detergent is usually added. The water temperature is normally quite warm, 50 to 60 degrees celcius.
