Degassing is nothing more than running the ultrasonic cleaner with no records in it each time you fill the tank with water, prior to starting your record cleaning. It removes oxygen from the water and allows proper ultrasonic cleaning. If you have a unit with the degas feature installed you simply fill the tank and hit the degas button/feature. If not, fill the tank, turn it on and run it with no records for about 12-15 minutes.
