Ultrasonics – applying science to cleaning technology

Ultrasonics is a trade term used to refer to the use of high-intensity acoustic energy to clean materials. Ultrasonication offers great potential in the processing of liquids and slurries, by improving the mixing and chemical
reactions in various applications and industries. 

It generates alternating low-pressure and high-pressure waves in liquids, leading to the formation and violent collapse of small vacuum bubbles. This phenomenon is termed cavitation and causes high speed impinging liquid jets and strong hydrodynamic shear-forces.


Cavitation is a general term used to describe the behavior of voids or bubbles in a liquid. Cavitation is usually divided into two classes of behaviour: inertial (or transient) cavitation and non-inertial cavitation.  Inertial cavitation is the process where a void or bubble in a liquid rapidly collapses, producing a shock wave. Such cavitation often occurs in pumps, propellers, impellers, and in the vascular tissues of plants.

Non-inertial cavitation is the process where small bubbles in a liquid are forced to oscillate in the presence of an acoustic field, when the intensity of the acoustic field is insufficient to cause total bubble collapse. This form of cavitation causes significantly less erosion than inertial cavitation, and is often used for the cleaning of delicate materials.

So what does this science mean in practical terms?


All this science means is that Ultrasonics is an extremely efficient method of cleaning – as the vapour cavitation is concentrated at the surface of immersed objects, dirt and soil is removed and bound in cleaning medium (usually water + cleaning solutions). In practice the presence of suspended dirt in the process improves efficiency by increasing the surface area for cavitation.

This results in a very effective cleaning process for most household contents. Dirt and odour is eradicated in a few seconds, simply by immersing the object to be cleaned into the Ultrasonic bath for a few seconds, or minutes, depending on the material being cleaned and how dirty it is. Contents that previously could have taken hours can be cleaned in minutes, and many contents that were unrestorable can now be returned to their pre-incident condition very cost effectively, and without the need for several hours of labour intensive cleaning.

The Ultrasonics Cleaning System can also be used for general cleaning, when fire or flood has not contaminated the contents.  Rainbow International has 50 Ultrasonic Cleaning Machines within its network, strategically located across the UK, ensuring every region has access to this advanced cleaning technology. A centre of excellence has also been established in Rainbow’s bespoke new training centre, based in Mansfield.

The benefits of Ultrasonic Cleaning What Can Ultrasonics Clean?
  • Unique technology provides higher restoration rates than previously achievable – cleaning of delicate and complex articles is possible.
  • All types of electrical goods can be restored or cleaned with very high success rate.
  • Simple operation and very low chemical usage – more environmentally friendly than other cleaning systems
  • Ideal for commercial or domestic goods following fire & flood situations – also the system is perfect for general cleaning – dirt and grime is washed away almost instantly.
  • Cleans and sanitises to a much higher degree than conventional “wet cleaning”.
