An ultrasonic cleaner is a device that is used to clean items, such as jewellery. Using ultrasound waves and chemicals, this jewellery cleaning machine can remove foreign particles such as dirt, oil and tarnish, as well as polishing compounds such as Tripoli and rouge from delicate jewellery pieces. High-frequency waves, usually from 20-400 kHz, are sent to pull the unwanted particles off your jewellery, leaving everything from bracelets to gold pendants spick and span and rid of all contaminants.
We use this process for jewellery cleaning as the ultrasound properties create bubbles, which are induced by high-frequency pressure waves. These bubbles cling to particles and then agitate the liquid, producing high forces which then remove any unwanted substrates from the jewellery. The ultrasonic jewelry cleaner focuses on the parts of your jewellery that are otherwise unreachable when coming to cleaning manually.
Note: Not all jewellery should be cleaned using an ultrasonic cleaner. Ultrasound may damage softer gemstones, such as pearls,opals, emeralds and turquoise – also gemstones whose colour has been enhanced through heat treatment should not be used in an ultrasonic cleaner, as the ultrasound waves can dim the brightness of their colours.
