How is ultrasound used for cleaning?

Ultrasonic cleaning uses high-frequency sound waves to dislodge dirt and contaminants from objects. The process works by generating cavitation bubbles in a cleaning solution. These bubbles implode, creating localized high pressure and temperature that disrupts and removes particles from surfaces. The frequency of ultrasound typically used is in the range of 20-40 kHz, which is above the range of human hearing. The intensity and frequency of the sound waves, as well as the cleaning solution used, are important factors influencing the effectiveness of the cleaning process. Different materials and levels of soiling may require adjustments to these parameters for optimal results. The process is often used for cleaning delicate items, intricate parts, and items that cannot be cleaned with harsh chemicals or abrasive methods.
