Degas: When cleaning heavily soiled or greasy items or silver, copper or brass items, chemical
solutions need to be added into the water. The solution may form many small droplets and take a
long time to dissolve in the water. Newly added water may generate many air bubbles on the tank
walls. These will reduce the cleaning effect in the beginning phase of ultrasonic cleaning. Turning
on the degas function will dissipate the droplets and the air bubbles, usually in 90 seconds, and
