Ultrasonic cleaning is the state of the art in instrument cleaning technology. This process is dependant upon the rapid formation and violent collapse of minute bubbles in a cleaning solution, a process called cavitation. Cavitation is produced by introducing high frequency (ultrasonic), high intensity sound waves into a liquid. The expansion wave causes a reaction so dramatic that molecules are ripped apart, creating the microscopic bubbles. The bubbles contain a partial vacuum while they exist and as the pressure around the bubbles becomes greater the fluid around each bubble rushes in, collapsing it very rapidly. When the bubbles collapse, a jet of liquid is created that travels at an extremely high rate. An associated rise in temperature as high as 5000 degrees celsius occurs. This extreme temperature combined with the liquid jet's velocity, up to 20,000 pounds per square inch,  provides a very intense cleaning action in a very concentrated area. This extreme agitation by countless small and intense imploding bubbles creates a highly effective scrubbing action of both exposed and hidden surfaces immersed in the cleaning solution. The result is an instrument thoroughly cleaned by high frequency sounds waves instead of the caustic chemicals commonly used in traditional Chem Cleans. This process is highly effective at removing calcium deposits and corrosion while preserving the quality of your instrument.  Once you're tried it you'll never go back to conventional cleanings again.
