Our technicians are working at the fresh water rinse station of our Ultrasonic cleaning system. Items that are able to be wet cleaned are placed into a pre-soak tank, then transferred to an ultrasonic chamber where sonic (sound) waves will vibrate the soils (soot, grease, grime( from the item. Then the cleaned items are rinsed and moved into a drying oven. The machine is effective at rapidly removing difficult soil from delicate items such as ceramic ornaments, glassware and others.
