How is ultrasound used for cleaning?

Answer 

Ultrasound is used to clean ‘hard to clean’ parts of objects such as spiral tubes, odd-shaped machines etc.

The object to be cleaned is placed in a cleaning solution and ultrasound waves are passed into the solution.

Due to their high frequency, the ultrasound waves stir up the cleaning solution.

Due to the stirring, the dirt particles of the object vibrate too much, become loose and get detached from the object and fall into the solution and the object gets clean.
