Restored through ultrasonic cleaning

At the heart of Ultrasonic Cleaning is the bubble; actually, lots of bubbles. These bubbles are created by sound waves as those waves move through water. This is known as Cavitation which is simply the formation of bubbles (a cavity) in water. If you’ve ever seen the foam left in water by a spinning boat propeller, then you’ve seen cavitation in action.
Since bubbles such as those created through Cavitation are just empty space, there’s nothing to keep them open. As a result, these bubbles collapse, or implode, almost as fast as they are created. In our machines, this happens millions of times per second. This constant implosion produces tremendous vacuum energy in the form of heat and pressure. It’s this combination of heat and pressure which gives Ultrasonics its cleaning capability and power.
