Keeping BLC in a keg long term?

Hello everyone!

Quick question… I have a spare keg I was thinking of filling up with BLC, diluted to suggested strength, having it on hand whenever I clean a line prior to a keg change and such. Would keeping BLC in the keg for weeks or even months cause any problem? Any other things to note about doing this?

Appreciate it!

It’s basically lye water, so it should be fine. That said, it works best warm/hot
