Lots of people have noted on here that they mix up a batch of Starsan and use it over and over for "a long time" or "several months." How can you tell when it will no longer be effective?
Someone mentioned testing the ph level, but I also am not sure what the best way to do that is.
Thank you!

Some people just use it as long as it stays clear. While this is probably OK, I prefer to use a pH test for the recommended level (≤3). I just use the cheap pH test strips. A little tube containing a whole bunch can be had at finer homebrew supply outlets everywhere. I got mine from Midwest........

For .50 cents per use I mix up a new batch of starsan for every use, and keep a spray bottle full for the little areas. It might be wasteful but I know its fresh. And instantly cloudy with my water. But still ok because I check the PH with my digital meter.

I'm now converting to PBW & Starsan and was wondering how long you let things soak like the racking cane, tubing auto siphon etc
Do you let them soak in PBW. Or just Starsan ?

Thanks.

Anything I'm cleaning with PBW gets soaked in hot (faucet hot) PBW mixed according to package directions for 1/2 hour. Star San is a contact sanitizer. Any time works, as long as all surfaces to be sanitized are covered. Also, SS only works while wet. Most of my Star San is applied with a spray bottle. Very, very economical.

How long can 1 step be used for? I may bottle tomorrow and I am going to fill my bottles now with 1 step and let them sit. Also, if I sanitize my equipment / bottles how long can i let them sit before I have to re sanitize?

anyone use ethanol? I have a still and when i have a bad batch of beer i distill it to around 88% pure ethanol and use it. or I just ferment a few kilos of sugar and distill it when I am having a lazy night in. the wife loves it too cause aint nuttin this stuff can't clean or kill! got mould? one spray and the toughest build up of mould just fades away before your eyes

a quick spray of ethanol and a blast with the blowtorch and anything is good to go. also makes it pretty easy to keep hands sterilised, and any siphons etc

? about keeping star san and the foam

I had a cleaning tray full and open to air for a few days. pH is still <3, but there is a slime that settled onto everything sitting in it. it's very slippery and takes some rubbing under water to get it off. it sure isn't something I want on anything that goes into the beer

when rinsing bottles with star san pouring it out leaves a ton of foam in there. Can that affect beer head? the last batch of bottles had some foam that was clearly from the star san sitting in the air space after bottling/capping.

other than these worries easyiest, and probably near cheapest sanitizer when you reuse. Also don't need to throw out when it gets cloudy. It is sanitizing as long as the pH is low. (they say like <3 as a CYA statement, but people say it is good up to like 3.5)

How long does Star-San keep? How do you know that you need to replace it?
Same question for Sani-Clean?
