Home > What is ultrasonic cleaning?

What is an ultrasonic cleaner and how do they work?

An ultrasonic cleaner works very simply by generating sound waves in water, which in turn, produce very small bubbles which get behind the dirt and grime to dislodge it. The sound is beyond the human audible level (ultrasonic). Most of the cleaning machines we sell have a frequency range of 42Khz, although the larger industrial cleaners operate at 28Khz.

How can sound waves clean your items?

Ultrasonic cleaning is a long standing, efficient and well proven process. Without getting too complicated, ultrasonic cleaners create a physical effect called "cavitation". This is where bubbles are formed when ultrasonic sound travels through a liquid. When the size of the sound wave increases to a level when water cannot hold it, the sound literally tears the water apart and millions of vacuumed bubbles are formed. The sizes of the vacuumed bubbles rapidly decrease until they collapse and implode. The action of these imploding bubbles releases tremendous amounts of energy. The huge amount of pressure released by each bubble as it implodes is responsible for the effective cleaning action. In simple terms, dirt is blasted from the nooks and crannies by lots of tiny bubbles getting behind the dirt and grime. 

The ultrasonic cleaning takes place everywhere the liquid can reach. During the cleaning process the article being cleaned is submerged into water or cleaning solution, millions of microscopic sized bubbles created by the ultrasonic generator (transducer) are capable of reaching into fine cracks to clean very thoroughly. This phenomenon is especially useful for efficient cleaning of intricate patterns on, for example, fine jewellery.

Is an ultrasonic cleaner environmentally friendly?

Yes, because the main ingredient is water, we believe our range of ultrasonic cleaners are environmentally friendly, providing fantastic cleaning results. Ultrasonic cleaning technology is now a well recognised way to clean many different things and has been developed in an a way it is affordable for home use. That said, to give your jewellery the "wow" factor, you should also use a cleaning solution. -

Which ultrasonic cleaning solutions do I need?

Although jewellery can be cleaned with just warm tap water and a small amount of washing up liquid to help remove grease, this alone will not remove dulling and tarnish. We do sell special additives to help speed up the cleaning process and greatly enhance the overall results. For cleaning engine parts or carburettors we highly recommend a specific cleaning fluid.

What can I clean using ultrasonic technology?

This list is almost endless. Provided the product is non porous and can be immersed in water, almost anything can be thoroughly cleaned. Here are some examples:

    What jewellery should I avoid putting in an ultrasonic cleaner?

    There is very little you can't clean, but if you have any doubt we strongly recommend you contact the manufacturer of the particular item you want to clean first. However we would not recommend the following without getting approval from the manufacturer first: Some precious stones eg, emeralds Some plastics are porous and the ultrasonic cleaning can cause some whitening.
  • DO NOT clean precious stones without gaining approval from a jeweller first. Ultrasonic cleaning is not suitable for certain types of precious stones. Please use the table below as a guide only
