    A long time, especially if you use soft or distilled water to mix it up. It is supposed to be effective unless the pH is over 3, or until the solution turns cloudy. Since I sometimes forget and mix it with tap water, it turns cloudy right away so I checked into it, and it's still supposed to be effective as long as the pH doesn't rise >3.
    I've been brewing about 20 years, and using star-san for about 13 years and I'm on my second bottle!

    Thanks
    I'll check the PH status before using an old solution.
    Cheers! for the third bottle.

    I go through a 32oz bottle every year, I'm either very clean or wasteful

    My last 32 ounce bottle has lasted three years. I generally can get enough from competitions that I don't have to buy the stuff.

    Yep- second bottle. :) As I said, I mix it up a gallon at a time- and use, reuse, etc- I usually spill it all before needing to throw it away. I make wine also, and have been using starsan for all of my sanitizing for years and years.
    You don't need to soak carboys or kegs and things- just get them wet with the star-san. Pour out and then onto the next one.

    Especially with beer lines and silicone tubing.... after soaking in a Star-San for a few days, the coating of the tubing gets slimey, as if the tubing is degrading or breaking down.
