47KHz Ultrasonic Cleaner for Jewellery
This ultrasonic cleaner operates at 47KHz to create millions of microscopic bubbles that reach every surface of jewellery, glasses, watch straps, dentures and retainers. The 360-degree cleaning action removes oils, soap residue and lotion in about five minutes. It is designed for anyone who wants professional-level results at home without the cost of repeated shop visits.
304 Stainless Steel Tank with Anti-Skid Feet
The 400ml tank is made from 304 stainless steel for corrosion resistance and easy wiping after each cycle. Anti-skid rubber feet keep the unit stable on wet bathroom counters, while multiple cooling vents allow safe, continuous operation. One-touch control starts the selected programme and the machine shuts off automatically when the cycle finishes.
Four Preset Modes for Different Items
Choose from Jewellery, Glasses, Watch or Automatic modes to match the item and level of build-up. Each mode adjusts the cleaning time and intensity so delicate pieces are not over-stressed. Adding a suitable cleaning solution, which is not included, improves results on heavily soiled pieces. The compact shape fits in a toiletry bag for travel use.
