Ultrasonic cleaning removes dirt from items like jewelry and surgical instruments by utilizing high-intensity ultrasonic vibrations within a liquid tank.1
The cleaning action is primarily driven by two physical processes:
- Cavitation: The ultrasonic waves induce cavitation—the formation and subsequent collapse of bubbles—within the liquid.12
- Turbulence: These vibrations and the resulting cavitation create intense turbulence in the cleaning fluid, which effectively dislodges contaminants from the surfaces of the submerged objects.1
This method is highly effective for cleaning intricate items, such as small machinery or dentures, and is frequently used to enhance degreasing processes.1
