What is an Ultrasonic Cleaner?
An Ultrasonic Cleaner is a jewellery cleaning device that uses a combination of ultrasound waves and chemicals to get rid of dirt, tarnish, oil and polishing compounds from your precious metal jewellery. To do so, high-frequency waves are used to remove any unwanted or foreign particles from your jewellery by creating bubbles that gently cling to the dirt. The bubbles then agitate the liquid, which produces high forces that eradicate said substrates, leaving it looking shiny and free from any contaminants.
Why Use an Ultrasonic Cleaner?
Over time, jewellery naturally collects dust, oils, and polish build-up that dull its shine. While brushing and polishing can help, they can’t always reach the intricate crevices where dirt hides. Ultrasonic cleaning is a trusted method used by professional jewellers to restore sparkle, remove stubborn polishing compounds, and preserve the condition of jewellery — without the need for heavy scrubbing.

How to Clean Jewellery With an Ultrasonic
Step 1 – Setup
Fill your Elma ultrasonic tank with deionised or distilled water. Add a jewellery-safe ultrasonic solution, carefully following the dilution instructions on the bottle. Using the correct mix not only protects the metal but also enhances the cleaning action.
Step 2 – Temperature & Settings
Set the ultrasonic to 50–60°C. Elma machines make this easy with precise digital controls. Allow the solution to heat fully before placing jewellery inside for the best results.
Step 3 – Placement
Always place jewellery in a mesh basket or suspend it with pliers — never place items directly on the base of the tank. Avoid overcrowding; proper spacing ensures the ultrasonic waves can clean effectively.
Step 4 – Cycle
Select a cycle time of 3–10 minutes, depending on how dirty the jewellery is. The digital timer makes this simple, and the powerful yet gentle ultrasonic waves will lift dirt and debris with ease.
Step 5 – Rinse & Care
After cleaning, rinse jewellery thoroughly with clean water. Dry using a lint-free cloth or compressed air. Avoid using the ultrasonic on soft or treated stones, and always inspect items first to check they are suitable for ultrasonic cleaning.
