Leaving Starsan in the Cornies

[Spyd3r]

When not in use, is this a safe practice?

Is there anything that it can hurt?

i do it...havent had a problem yet. I the pH raises above 3.2 (i think...maybe 3.4) it becomes unusable. I leave it in and then do a quick rinse with more when im ready to use to rinse the diptubes and liq out/gas in
