Yeah that was the idea, to be able to reuse the star san. That is a good idea with the tinfoil. I think that is what I will do. Do you (llazy_llama) use them right after you pop the tinfoil off? I feel like I would get paranoid that something snuck in there under the foil. What about a sanitized solid bung? I would just like to sanitize when I am finished with the carboys and have them sanitized and ready for next time.

The last time that I filled a keg I mixed the Star San in a keg and left it there. Last week (about a month later) I wondered if it was still good? I called the number on the bottle to ask 5 Star if it was still good and the man I talked to said if I didn't use distilled water that I should probably throw it out. He said if I had some litmus paper & could test the PH then it would be OK if the PH was 3.5. Since it is so cheap to just mix another batch I threw it out. The next time I order I will probably order some strips. He said if it was still clear then it was most likely OK but he didn't think it was worth the risk.
