KECOOLKE 2.5L Large Capacity Ultrasonic Jewelry Cleaner with Degas, Heating and Time Setting 160 Watts Powerful Double Transducers for Jewelry Ring Silver Coins for Gifts

The sonic cleaner vibrates the water 42,000 times per second to remove hidden dirt. With the highest vibration frequency in the household, protein dirt can be removed and this dirt adheres to small parts and cracks that are difficult to treat with water. By producing micro-vibrations in the water, the sound vibration wave penetrates the precious metal that the brush cannot reach, and cleans stubborn dirt.
