Is it ok to store StarSan in a corny keg? The tech sheet on the Five Star website does not have any information on recommended storage containers. Thanks for your advise.

When I questioned 5 star about this I received a response that was along the lines of: "as long as the diluted starsan does not become cloudy it is still viable"

I was told that storage in a SS vessel was alright but to avoid long term contact with copper.

"but to avoid long term contact with copper."

It's a good way to shine up a IC that's oxidized. But the StarSan turns green and thrown away after using it for that.

If you mix 1 ounce to 5 gallons, as per the instructions, I can't imagine how it could be harmful to a corny even long-term. But I store my empty cornys on a shelf, so I don't want to have them filled.

You may consider filling a corny with StarSan overnight, then using CO2 to push it out (or into another corny). The few resudial drops shouldn't harm the stainless.

I keep a single 3 or 5 gallon corny of StarSan around pretty much always...

Never know when I will need to sanitize something

Actually, I believe it is ok to store it long term. But I don't know for a fact if it is.

The reason I believe this is that I read some info about re-passivating stainless steel, which is done with a strong nitric acid. I figured a week phosphoric acid would work also, it would just require more time.

SO, I left some old star san at the working solution of 1 oz./5 gallons for about a week in two of my brew kettles that I had recently had couplings welded into.

It worked. I'm thinking it actually repassivated the steel.

Also, Star San is composed of active ingredients that are approved by the FDA as a no-rinse sanitizer in food processing equipment. Specifically mentioned is its use in dairies. The processing equipment is stainless steel. I reason that a no-rinse sanitizer approved for food processing stainless steel would not corrode the steel.

Is there a metalurgist in the house?

I routinely keep star san in my corny's for many months. I can say with confidence that it does no harm.

Thanks, all. Seems that it is certainly safe for a week or two. I need to brew more so that each keg never has the StarSan in it for more than a couple of weeks. Yeah ... that's the plan ...

That's awesome. I also store my kegs upside down and open, despite the spiders... And after two years, there were quite a few. Now I feel like I have 'expert' advice to do that.
