  • Ultrasonic Cleaning

    Ultrasonic cleaning is a method of cleaning using powerful ultrasonic vibrations. The vibration creates a number of small cavities in the liquid and removes extra deposits with the pressure generated at that time. There is no problem with precious metals, but if you clean jewelry with gemstones, it is necessary to handle it carefully because it may cause cracks.
