Degassing: what it is and when to do it

What it is

Degassing is the first removal of the gases that are dissolved in the liquid. The cleaning comes from tiny bubbles that collapse with force. With gas in the liquid the collapse is softer, and the cleaning is weaker.

When to do it

• Every time you fill the tank with new liquid.
• When the liquid has stood unused for 24 hours or more, because it takes up gas again.

How to do it

Run the cleaner with only the liquid in it for 5 to 10 minutes before you put anything in. That is the time Branson gives for its tanks. Check the manual for your own model.

Some cleaners have a degas function for this: 27 of the 180 cleaners in our database have one. Without it, a normal run with an empty tank does the job.
