How long does starsan last

My solution used to get cloudy in a matter of moments, now I have a 1 gal solution that's crystal clear several days later. I bought a bunch of distilled water store didn't have RO at the time and I made some StarSan solution out of it.

I've had it stored for about 6 months It isn't crystal clear, but it isn't as cloudy as with tap water. It still foams up when I shake it. Anyone have experience with plain distilled water. Also, does anyone know where I can get bottled R.

The spray bottle was a little cloudy and foamed medium. A gallon jug I had was clear and foamed a ton I used that. Still, I'm looking for good, RO bottled water in Chicago area so I can make some up and keep it for awhile. Any suggestions? Joined Oct 9, Messages Reaction score Sorry to revive this ancient thread, but I had a related idea, today.

I was trying to figure out how best to push sanitizer through "picnic" style taps, and it occurred to me that I could just dedicate a keg to StarSan, keep it at "serving pressure", and just tap it when I want to run through the hose. Obviously, I'd still take everything apart and give it the bucket treatment; I'm talking about for the actual inside of the length of the hose.

Has anyone does this? Is this "brilliant" or "ridiculous" or somewhere in between?

This is a light production environment where they brew a few batches a week.

As has been said here before, probably, It will keep for a long time IF you use distilled or RO water. If you mix it with tap water, the minerals will neutralize it in days massive variables, so there's no telling how fast yours will last. ChandlerBang Well-Known Member. So here's an interesting twist to this thread. What if I've had a couple gallons of starsan in a bucket for, say, two years roundabout. Smells good, looks good.

GFBrewboy Member. Has anyone tried using dehumidifier water for Star San solution? Any bugs should be killed by the Star San. I would not count on Star San killing an entire biological stew that is condensate. It's not even clear it kills wild yeast, never mind mold spores, etc ChandlerBang said:.

Yeah, that's actually not true. I don't know what kind of plastics Star San or perhaps more on target - phosphoric acid will consume but the plastic spigot I use on my Star San bucket will reliably be eaten up over a couple of years of constant soaking exposure to the point that the nylon lock nut will slip over the reduced spigot threads.

Also, years ago there was a practice of stuffing Delrin "mixing sticks" down corny keg dip tubes to compensate for too-short beer lines.

Interesting thread. My LHBS says as long as the stuff foams up during use, it is good. And mine always starts out cloudy! He lets his keg and carboy washer run for minutes.

Not sure how long. I do know that using kmeta for sanitizing is good only momentarily. StarSan acid does not harm plastic. It slowly eats away at metal. So it depends on what your bucket is.

I would only need to invest in a regulator. I'm planning on brewing minimum of 8 times this year.

Bad idea? FWIW, this is what we do, and it seems to work quite well. If nothing else, it's a convenient way to rinse-out bottling gear and similar. I drive my sanitizer at pretty low pressure and bleed the keg, but sometimes still end up with mild carbonation, which I find annoying bubbles in the line means sanitizer isn't touching that spot. Easy work around, but I'm lazy.

I stumbled onto this thread and it hit upon an issue I've been thinking about. I keep my starsan mixture in a 6 gal food grade bucket and I've noticed the bucket gets a bit sticky on the inside and hoses and beer line get foggy.

How long does the StarSan last in that bottle? Is it good forever? Improve this question. Add a comment. Active Oldest Votes. Improve this answer. Do you actually test the pH? Honestly, no. I just dump it every couple times I brew. Except one time I found a dead bird floating in the star san bucket, so I obviously dumped that on. That said, I'm not sure that I'm anal-retentive enough to test it every time, either. The pH rule is the best guide - my starsan turns cloudy immediately, but it's still effective.

I keep in an airtight container and test every couple of weeks, and again if it gets a bit soiled. What will affect it is: The factor at which you dilute it, if you add too much water it looses its acidity and will not be effective.

Use only 1 oz Star San per 5 gallons of water and just 1 to 2 minutes of contact time.

Used as a soaking solution, it can also be applied by hand wear gloves or with a spray bottle. Reusable: a solution of Star San will remain effective for up to three to four weeks in a sealed container; it is effective as long as the pH is 3 or lower. Additional information SKU - 8 oz - 16 oz - 32 oz Star San is safe for use on all surfaces, but use caution since it is an acid; contact with soft metals, rubber, and plastic should be kept to a minimum.
