Excellent advice this knocks out all the confusion about how long the solution will stay effective, thank you.

[@Beerstories]

You’re welcome 😊

I've used starsan much older...i was told once it gets cloudy then it's time to make a new batch. Cheers 🍻

[@Beerstories]

Cool 😊 Mine is used up after 6months, so I don’t have any experience with longer than that

[@whybrewathome]

I also prefer to have a bucket of StarSan solution, so that it is ready when needed. I make it from RO water, since it will not go cloudy (a least so I was told, I keep it for 1-2 months and in that time-span I see no cloudiness). I will definitely check pH going forward, didn't think of that, so thanks :-)

[@Beerstories]

Cool 😊

I tend not to go through that much so I only mix up 1US (3.78l) gallon at a time. I buy a gallon of distilled water and add 6ml of star San concentrate. I too have kept and used it for about 6 months…marvelous stuff.

[@Beerstories]

Cool 😊

Forever

[@Beerstories]

Probably 😊

[@MadMax00215]

I do the same. I make 5 gallons and unless it's dirty I keep it for about 6 months maximum. With the exception of my hose, auto siphon, and air locks (that I put right into the bucket) I don't dump any I take out back into the bucket, it goes down the drain.

[@MadMax00215]

I should add that I make mine from filtered water (charcoal filter) so it doesn't go cloudy. Distilled or RO is even better.

[@Beerstories]

Yes, that's right :)

[@kb2vca]

Except the manufacturers of Starsan themselves, say one hour is the maximum they recommend its shelf life once mixed. Is the issue ONLY the pH , or might some active ingredients bind with oxygen or other compounds and elements to reduce or neutralize its effectiveness?

[@Beerstories]

I know it says that. I think, they have to by law. As long as it it still foaming and the pH is good, it's not a problem. I and many of the brewers I know, have done this for many years without problems

[@simonevdw90]

What water do you use?

[@Beerstories]

Many people suggest RO water, but I’ve always just used tapwater. My tapwater is pretty hard, but with chlorine. Chlorine can make it last shorter from what I have read. But as long as it is foamy and pH is lower enough, you’re fine. So that’s what you should look for 😊

[@simonevdw90]

@@Beerstories I live in the Netherlands and we have very clean drinkable water from our tap. I think it’s fine to use. Thank you!

[@Beerstories]

It should be 😊 You’re very welcome 😊

[@s18169ex3]

The company says it has expired after one hour of being mixed

[@Beerstories]

Yes, but it still works 😊 Mine works fine up to 6 months and never had any infections 😊

[@retireorbust]

I think what they mean is if it's been air dryer it will stay sanitized for one hour and of course that's on average. This does not address the liquid itself.
