What are the effects of storing things IN Star San for extended periods?  I'm thinking mostly for things like auto-siphons and tubing that never really dry out completely or could retain some moisture and encourage mold, etc...

As much as I love Star San, I know it's an acid and worry about it eating away at things....


Thoughts??
 ???


After use, I sanitize and take my autosiphon apart (just the "racking cane" out), and place it upright so it can dry and hang my hoses in a manner that they will drip dry. I have never had mold (or other growth) in my auto siphon or my tubing.

...Yeah 3 or less...here's the mfg's data sheet.
It used to be 2.4. Looks like they lowered the concentration.

Really?  I don't recall it ever being 2.4, but that doesn't mean it wasn't!

In a reply from Jon Herskovits of Five Star Chemicals (I had asked him about long term storage in a carboy):Yes, storage in a glass container or plastic (HDPE) would be suitable.

"Star San will kill below a pH of 3.5, when the pH drifts above 3.5, it means
that it is no longer effective.  You could also Titrate to determine the
exact ppm of acid and DDBSA.  Most people use the pH method.
