Degassing of liquid

Newly mixed cleaning liquid is saturated with air which lessens
the cleaning effect of the ultrasonic activity. By sonification of
the liquid over a period of several minutes before the actual
ultrasonic process the tiny air bubbles in the liquid are
eliminated.

switch-on and switch-off press the degas key.
