Star San and corny kegs

[mookow]

Can I store StarSan in a corny keg indefinitely? Or will it hurt the keg to do so? And how long in a closed enviroment (say, 2.5 gallons of StarSan solution in a 5 gallon corny keg) will the StarSan stay potent?

There's a guy in my homebrewing club who stored Star-san in a Corny keg. it ate thru the SS in a few weeks, leaving pinholes at the water line inside the keg. I wouldn't do it. Just sanitize the keg before you use it.

I store my StarSan solution in a 5-gallon carboy. I have reused it for months. It says it is good as long as the pH stays below... um... was it 3? Dangit, I'll have to look that up, but anyway, it stays good for a long time! StarSan may be expensive up front, but you can stretch it quite a ways.

I'm glad this thread was started, I was just about to do the exact same thing without asking. The SS thing never even occurred to me.

Star-san is an acid. It makes sense that it would eat thru SS with continuous contact.

Toney, pH of 3 or below is correct. I continually check mine and add a few drops as needed.

again,

thank you gentlemen for another fine thread. I will empty mine tonight and check it... been in there about a week.

I would be very cautious, as been pointed out, as while it is in SS the super low pH of this will cause some problems. The same thing with storing it in plastic. Your plastic will have a super slimey feeling to it and be ruined for good if you use it for extended storage.

I store my star-san in a corney,but it is an old corney that i don't use for beer.As stated above,i would be cautious as it is an acid.

Was just wondering what you added a few drops of, assuming the ph goes over 3, right?

Just getting into kegging and looking forward to a nice cool glass of draft beer. Apart from sharing with friends and family, considering giving up bottling all together. Curious about how to save money with Star San.

Thanks!

A few more drops of fresh star san. You can really stretch it out if you keep checking the pH and adding a wee bit as necessary.

That's great!
It makes it so much easier to address the drudgery of sanitizing to keep that kind of knowledge around.

Thanks again.

Yeah, same with your beer lines! If you leave them in starsan overnight, they're ruined.

Ruined as in structural damage, or as in being unfit for brewing in?

When you feel the slime, you will throw the thing out, I guarantee it! There's no way you will want to use the gooey thing again.
