1.3L Stainless Steel Heater Timer Ultrasonic Jewelry Cleaner Introduction Ultrasonic cleaner is a microprocessor-controlled device through applying ultrasonic or high frequency sound waves to clean jewelry and other delicate items. Ultrasonic cleaning is based on the cavitation effect caused by high frequency ultrasonic wave vibration signals in fluid. Microscopic bubbles that expand and collapse rapidly cause cavitation, which create a wonderful cleaning action on the surface of object being cleaned. Features Durable stainless steel construction. Stainless steel tight fitting lid with handle to prevent water heat from diffusing. Ultrasonic cleaning and heating can work at the same time. High efficiency saves cleaning solvent, thermal energy, work place and labor! Large digital timer and temperature display for precise wash time and temperature control. High efficiency clean for teeny blot particles. Use only tap water for general cleaning, you also can add about 5-10 ML of detergent into water to enhance wash result when needed. It is more convenient and efficient than hand wash, steam cleaners, high pressure water jet cleaning or other machines. Just plain tap water is enough, if no special results required.
