How do ultrasonic cleaners work?

Ultrasonic cleaners are useful in a wide range of industries, including the electronic, healthcare and automotive industries.

They use a cleaning solution filled with millions of minute bubbles created by high-frequency sound waves. These tiny bubbles implode to create a powerful and effective scrubbing action that removes contaminants and dirt from a surface. This process is known as cavitation and is especially effective at cleaning intricate parts and getting into hard-to-reach areas. You can read more about cavitation on the Science Direct website here.

Understanding ultrasonic cleaners

Whether you have a small or large ultrasonic cleaner, it will have a tank that is filled with a type of cleaning solution. It will also have an ultrasonic generator to produce the all-important sound waves that travel through the solution to create the bubbles. These then collapse to release the energy which leads to the cleaning action that a small or large ultrasonic cleaner needs to do its job. This can be effective at cleaning an array of items ranging from jewellery and electronic components to surgical tools and dental instruments.

Ultrasonic cleaners are similar to dishwashers in the way they combine detergent and water to remove dirt and contaminants. Also, they can be used to clean almost any surface or material that cannot be damaged by being immersed in liquid. In contrast to dishwashers, however, they use energy created by imploding rather than exploding bubbles.

Types and uses of ultrasonic cleaners

There are small portable ultrasonic cleaners that can be used in domestic settings and large industrial-grade machines for commercial use. They can be effective at cleaning engine components such as fuel injectors and carburettors, removing contaminants on parts in the defence and aerospace industries, and cleaning delicate components in mobile phones and computers.
