At present, the musical instrument industry has basically formed the relatively complete industrial production system, which can almost fabricate all of the musical instruments in the world, with complete categories and numerous kinds, including piano, violin, orchestral instruments, long flute, saxophone, brass instruments and so on. Secondly, for the cleaning of musical instrument accessories, the residual abrasive paste, dirt and wax should be cleaned. Therefore, various types of musical instrument ultrasonic cleaners were designed and fabricated according to the principle of ultrasonic cleaners in the market. They have been applied extensively in the cleaning and maintenance of various orchestral and metal musical instruments.  

     As for utilizing the ultrasonic for cleaning musical instruments, it mainly aiming at removing the dust, grease dirt, sweat and saliva congelations, the rust and leaked acid cannot be cleaned (Leaked acid refers to conduct acid cleaning for the musical instruments before paint spraying, eliminating the surface dirt on musical instruments,  the cleaning after acid cleaning is also necessary, at last, it is the paint spraying. In this process, sometimes the acid will be leaked and the acid fluid can not be cleaned. Leading to the acid remains after paint spraying. After a long time, there will be the black spots. The black spots will become larger and can not be cleaned.)   

It is known to all that various greases would be attached on the surface of copper components during fabrication process, such as stretching oil, engine oil and so on, copper rust will also be produced after long-time usage, making them dull, therefore, the daily cleaning for copper components is an indispensable procedure, but there are relatively high requirements for the cleaning of copper components, they can not discolor and oxidize. For maintaining the original brilliance of copper components, the professional cleaning device must be prepared, hence, can ultrasonic cleaning be utilized for cleaning the workpieces made of copper materials? Are there any advantages for utilizing the ultrasonic cleaning?

    Ultrasonic cleaning means to utilize its cavitation effect in clean-out fluid for cleaning the copper components. The ultrasonic transducer installed at the bottom of ultrasonic cleaning trough can shot ultrasonic to the clean-out fluid in trough by means of cleaning trough walls, under the high-frequency vibration of ultrasonic, millions of tiny bubbles can be produced in clean-out fluid, the formation, growth and quick breaking processes of these bubbles are called cavitation effect. Cavitation effect can accelerate the phase reaction between the dirt on copper components surface and clean-out fluid, promoting the dirt to scatter in clean-out fluid, after the cavitation bubbles break, high speed micro rapids will appear nearby, which can eliminate the dirt on copper components surface efficiently and prevent the copper components from damage.

Ultrasonic cleaning is not restricted by the shape of copper components, for the copper components with complex structures, deep and blind holes and narrow apertures, they can all be cleaned efficiently.
The ultrasonic cleaning technology can realize the automatic and batch cleaning works, improving the cleaning efficiency, reducing the labor intensity of workers. 
Ultrasonic cleaning has high cleanliness, for the contact cleaning medium, the cleaning effect is even. 
It can reduce the dosage of detergent, saving cleaning costs, and reducing environmental pollution.
The copper components can generally not be damaged by utilizing ultrasonic cleaning. 
From this, taking advantage of ultrasonic cleaning can eliminate the grease dirt or copper rust on copper component surface quickly, realizing satisfactory cleaning effect. But there is one point needs attention, for the grease dirt and rust attached on the copper components, suitable detergent should be supplemented for ultrasonic cleaning, because the detergent has chemical effect, while the ultrasonic possesses physical effect, only integrating physical effect and chemical effect, the hard dirt on copper components surface can be eliminated quickly.
