A few weeks back I picked up some distilled water, and mixed up 2.5 gallons of Star San with it. Normally, here in Chicago, the Star San mixture is cloudy by the end of the day, and the next morning it's getting that slimy feeling - both indicators it's time to dump.
But with distilled water, the PH stays nice and low - and 3 weeks later the Star San I made with distilled water is still crystal clear and foaming just like I made it that day. I put some in a spray bottle, and don't have to worry about it going bad.
The past couple weeks, having this bucket of sanitizer has been very handy - I've found myself having to switch out airlocks, rig up blow-off tubes, sanitize bottles among other various things, and not having to mix up sanitizer each time has been a real hassle-saver.
Is it economical/practical to do this all the time? I don't know - up to the individual. But if you plan on lots of brewing work over a period of a few weeks, this can be real handy. Just cover the bucket with a lid and fill up that spray bottle - cheers!
