As intimidating as it may sound, ultrasonic cleaners actually just use bubbles in lifting dirt off the object it is cleaning. Yes, the delicate bubbles that burst on the surface of the object being cleaned is so powerful as to do jobs when others have already given up.
Popularly referred to as cavitation bubbles, these are produced by the fast formation and speedy collapse of bubbles in a certain liquid, which is the result of high-frequency ultrasound waves. Machines that are more powerful create higher frequencies which results in more accurate cleaning. Finally, these microscopic bubbles are so hot and can reach temperatures of up to 10,000 degrees.
The process is quite simple too. The object is secured in an apparatus filled with ultrasonic liquid. When the machine, like the Crest ultrasonic cleaner, is turned on, ultrasonic waves are produced which create microscopic bubbles. In turn, as these bubbles form and burst in split seconds, energy is released which causes dirt and other impurities to break off from the object.
In the case of ultrasonic gun cleaners, the last iota of dirt, dust and rust are lifted off the brass or metal body of the weapon. The end result is a gun that looks as good as new, sometimes even better. No other method of cleaning could produce the same quality of cleanliness.
