Ultrasonic cleaning works by generating high-frequency sound waves in a liquid, which create millions of microscopic cavitation bubbles. These bubbles grow and rapidly collapse, releasing localized energy in the form of micro-jets and shock waves that mechanically remove contaminants from surfaces, including complex geometries and blind holes.
However, ultrasonic cavitation alone is not sufficient to effectively remove all types of contamination. The presence of a properly formulated cleaning detergent significantly enhances the process through several physical and chemical mechanisms:
