Default Do CO2 Lines Need Cleaned Periodically?

If the only thing that goes in the CO2 lines is CO2 (no beer gets sucked up through the CO2 line), do the CO2 lines need to be cleaned for each keg batch? I just kegged my first beer this past weekend and already looking forward to my next batch. I know the liquid line side needs cleaned but not sure about the gas line. Thanks.

Probably not. I still give mine a good cleaning once or twice a year though.

As long as you don't have beer flowing back into the CO2 lines they should be fine as is. If they were clean when you hooked them up they should stay clean as the CO2 lines make a closed system with the ball lock disconnects.

Here you can see what I do to prevent any problems with CO2 lines.

Each tank has a filter.
