Empty keg lines?

Just wondering what everyone else does with their empty keg lines if you don’t have a beer to tap immediately. Do you all leave them empty with a little cleaner left inside or what? Thanks.

It’s not recommended to leave cleaner in the lines for any longer than the 15-30 minute cleaning cycle.  It will leach into the line, and then back out into your beer.

After cleaning, sanitizing and rinsing, blow them out with CO2 and cap the faucets. If they will be empty for more than a few days, disassemble the faucets and lube all of the rubber.

An empty keg line is a sin. I’d schedule a brew day right away.
