What is the technology behind ultrasonic cleaners?

Ultrasonic cleaners work by using high-frequency sound waves to create microscopic bubbles in a liquid in a process called cavitation. It is not unlike how a domestic dishwasher works but instead of just cleaning household plates and cutlery, an ultrasonic cleaner can clean just about any metal, glass or plastic product.

Most ultrasonic cleaners have an ultrasonic generator which sits at the bottom of the tank and the tank is then filled with a cleaning solution. The generator creates soundwaves, usually between 20-400 kHz, which produce mechanical vibrations and powerful bubbles that travel through the liquid. The implosion of the bubbles creates high-pressure waves that effectively blast away dirt and grime from the surface of the object being cleaned.

The high-pressure waves also create a scrubbing action that can penetrate hard-to-reach areas, such as crevices and holes. Large ultrasonic cleaners can be used to clean a variety of different-sized objects and machinery.

Which industries use ultrasonic cleaners?

Ultrasonic cleaners are particularly effective at removing contaminants from objects with complex shapes and irregular surfaces, such as watches, jewellery, surgical or dental instruments and electronic components. The cleaning solution used is usually a mixture of water and a specialised detergent which helps to enhance the cleaning process. In a medical environment it is especially important to follow recommended guidance and regulations when using an ultrasonic cleaner.

How safe are ultrasonic cleaners?

Ultrasonic cleaners are mostly considered safe for cleaning materials such as glass, plastic or metal. However, it is important to follow the manufacturer’s guidance as some materials may need special care as they might not be suitable for cleaning using high-pressure ultrasonic waves.
