That is why the benzyl alcohol is in there though. It inhibits growth so thirty days is just a manufacturer guideline for safety.

I just buy the tiny thirty ml bottles so I finish them before the month is up anyway.

Thirty days is way too conservative in my experience. I use the same bottle for three months and never had an issue.

Small bottles are definitely the way to go if you want zero risk of degradation.

You guys are way too paranoid. A proper sterile technique lets that water last way past standard guidelines.

That is a fair point about the preservative agent but I still prefer playing it safe for my subjects.

Sterile technique only goes so far once airborne dust settles on the stopper over multiple uses.
