Jewellery

In the Ultrasonic Jewellery Cleaner section, there are three versions for most sizes of ultrasonic tank. In summary, the more money you pay for a model, the greater control you have over the jewellery cleaning process. The "manual" (dial adjustment) gives limited control. The "digital" range gives you full control over all aspects of the cleaning operation and importantly, you have a LED display showing the temperature of the water (it helps stop the operator plunging their hand into hot water). Degassing is standard on all our digital model. Finally, the touch screen with sweep function gives a deeper clean. Also the power can be reduced for cleaning delicate and fine jewellery.

• 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 retailer of the particular item you want to clean. Ultrasonic cleaning is not suitable for certain types of precious stones or costume jewellery. The table below as a guide only.
