Working principle

The principle behind ultrasonic cleaning is cavitation.
When the ultrasonic cleaner is switched on, 3-dimensional sound waves of alternating positive
and negative pressure are generated and transmitted into the water in the tank. These sound
waves created micron-sized bubbles that grow and build up energy during negative pressure and
implode at a very high speed during positive pressure (43,000 times per second). These
implosions of high energy bubbles create cavities that literally pull contaminants of the surface
(at speeds up to 400km/h). Due to the size of the bubbles, they are effective in removing
contaminants from the smallest of crevices but harmless to the substrate itself.
Usually water is used as cleaning agent as it is inexpensive and environmentally safe.

VTUSC6
As these items are soft, scratching may occur
during the cleaning process.
Ultrasonic cleaning may increase the gaps inside
welded joints, plated coating or glue which may
lead to breaking loose.
The strong penetration capabilities of the
ultrasonic waves may cause water to penetrate
weaker sealed watches.
Crack size may be increased by the ultrasonic
waves.
