ABSTRACT:
A workpiece is immersed in a cleaning solution in a cleaning tank. The cleaning tank has an ultrasonic vibrator disposed on its bottom for radiating ultrasonic energy into the cleaning solution to remove foreign matter or burrs off the workpiece. A deaerating device is connected to the cleaning tank for supplying a deaerated cleaning solution to the cleaning tank. The deaerating device comprises a sealed tank for being supplied with the cleaning solution from the cleaning tank. A vacuum pump or ejector is connected to the sealed tank to evacuate the sealed tank to release a dissolved gas from the cleaning solution which is supplied to the sealed tank and exposed to an evacuated space in the sealed tank.
