Why do I need to use a special cleaning solution
An ultrasonic cleaning solution plays a very important part in ultrasonic cleaning. It is needed because some contaminants are firmly attached to the items. And so, they will not be removed if only water would be used. The cleaning solution is effective in breaking the bonds that hold the contaminants to the objects. Also, the solution has ingredients that lower the surface tension of the water. These ingredients are called surfactants and they help in making the cleaning process effective. When the surface tension of the water is low, more cavitation bubbles are produced.
