Ultrasonic cleaning uses cavitation induced in a fluid medium by ultrasonic sound waves to remove unwanted contaminants. The small bubbles of gas created by the ultrasonic energy implode upon contact with an object and in so doing knock the contaminant loose & sweeps it away. Various chemicals can be used as the fluid medium depending on the compatibility of the object being cleaned and the contaminant to be removed. Ultrasonic cleaning is especially useful for components having internal passages that cannot be reached any other way. Our current chemical is non-toxic, non-corrosive, contains no acids or bases, safe to handle, rinses away cleanly, and is safe on plastics and most paints.
