ABSTRACT:
An ultrasonic cleaning tank with an ultrasonic vibrator mounted on its bottom is supplied with an aqueous cleaning solution which has been deaerated to a predetermined dissolved oxygen content ranging from 0.01 to 5 ppm. A workpiece to be ultrasonically cleaned is then immersed in the cleaning solution. Thereafter, the ultrasonic vibrator radiates ultrasonic energy into the cleaning solution to remove foreign matter and burrs off the workpiece.
