All household ultrasonic cleaning machines in the market will think of jewelry cleaning on the cleaning object, and almost all jewelry stores will be equipped with ultrasonic cleaning machines for jewelry. As far as the cleaning effect is concerned, ultrasonic cleaning is really excellent, but there are certain risks in using ultrasonic cleaning to clean jewelry.

The principle of ultrasonic cleaning is that through cavitation, acceleration and direct inflow, the irregular shape of various jewelry can be ignored and the dirt in the gap can be separated everywhere. For most jewelry, the cleaning effect is still relatively good. It is precisely because of this principle that some jewelry will fall off or crack after ultrasonic cleaning. Then why didn't all the ultrasonic cleaning machines on sale remind you which jewelry was not suitable?

Cavitation produced by ultrasonic cleaning belongs to mechanical oscillation of physical action, and the molecular structure of objects can also be changed by high-power ultrasonic action. Gutter Ultrasound has collected some gems that are not recommended for ultrasonic cleaning:

1, opal, pearl, emerald, malachite, Tanzanian zoisite, emerald, ruby, lapis lazuli, coral, etc.
