Multifunctional Ultrasonic Cleaner Jewelry Glasses Lenses Cleaning Machine 1. High-frequency vibration separates the air and water in the liquid, forming bubbles of 50-500 μm, which expand and burst under the action of sound pressure, achieving instant impact and continuously flushing objects, so that dirt and oil can be emulsified and peeled off. 2. Dirt is hidden deep in the gaps and cannot be cleaned by simple water washing. Multi-dimensional penetration into the gaps and high-frequency 360-degree all-round impact can clean places that are usually difficult to clean. 3. It can clean various styles of glasses, watch straps, jewelry, childrens toys and other objects, making you feel more at ease when using it. 4.
