Storing Star San in kegs

[Simonh82]

I'd like to start using the sanitation/purging method of pushing a full keg of star san out, into a spare keg to purge the keg of oxygen.

Is it perfectly fine to store star san in kegs long term? I know it's clearly safe in the short term but would it be OK if it sat there for a couple of months?

no problem, I actually keep a keg with star san in it constantly, refilling as it gets low.

I do this all the time and run the star San through the taps after kegs are empty

same here.
if you want piece of mind, you can check the ph if it’s been around for weeks.
if ph is 3 or less, it’s as intended.

Thanks everyone, that's reassuring to know.
