Generally, ultrasonic cleaning is safe for all materials; however, prolonged soak to ultrasonic cleaning solutions and chemicals   may interact adversely with the surface of certain metals.

For fine cleaning of very delicate jewelry, electronics with polished surfaces, it should be considering the frequency and power, instructions for safe use of an ultrasonic cleaning, consult the manufacturer of the product.

Note: Aluminum is a softer metal; surfaces can suffer pitting in ultrasonic cleaning. For cleaning aluminum parts, getting rapid and effective cleaning without damaging the parts is more difficult.

6.Are ultrasonic cleaners dangerous?

Ultrasonic cleaners will generate heat during the cleaning process.

You should never use flammable and explosive liquids in an ultrasonic cleaner. Dangerous conditions will occur if flammable and explosive liquids are used for ultrasonic cleaning.

In addition, do not use toxic cleaning solution, which is dangerous for the operator.

Ultrasonic cleaning is a physical cleaning method. When removing chemical contaminants on the metal surface, such as rust and paint, it is necessary to add a cleaning solution to the water.

Under the action of ultrasound, chemical contaminants react between the solution and the surface of the part, thereby improving the cleaning ability and shortening the cleaning time.

10.Are ultrasonic cleaners noisy?

In fact, the ultrasonic cleaner does produce noise. When the ultrasonic cleaner is working, the "zizi" noise heard by the human ear is caused by ultrasonic cavitation, which is called cavitation noise. If there is whistling noise, it is possible to eliminate it.

At present, manufacturers usually use a variety of methods to reduce noise without affecting the cavitation, such as using foot pads, or adding sound-proof cotton to the lid and optimize the equipment shell.
