This video is targeted towards auto repair and maintenance facilities. It briefly describes the mechanism and the advantages of an ultrasonic parts cleaner. For example, according to the narrator, “the ultrasonic unit is best at cleaning blind holes or interior surfaces that can’t be reached with a brush or spray.” The high energy ultrasonic waves are also touted for their ability to provide an “intense microscopic scrubbing action.” The labor-saving advantages are also summarized, as workers can simply place the parts and come back in a few minutes to pull them out, clean.
