Agree with some of what was said, depends on Temp. In a sealed clean tank it will last a while, in a bucket on the floor not long depending on the temp, and what you plan to use it for. Cheers

It also really likes to crust onto things like chrome plating. Oh and galvanized steel. We left a large bottle brush we use on our racking arms in our soaking tub overnight once and the next morning were like "Wait, where'd all the yellow go???" Crusted onto the twisted steel handle of the brush. So if you've got a parts tub you're soaking things in, over time it'll crust onto tailpieces, beer nuts, sanke taps, anything not rubber or stainless really. Course star san also likes to eat the chrome right off your parts, so there's that.
EDIT: Derp. Not star san. PAA. PAA eats chrome. Star san makes all your vinyl hoses clouded and slippery.

Star San is phosphoric acid and dodecylbenzenesulfonic acid. The phosphoric acid simply lowers the pH of the solution to an active range for the DBSA to do its work.
Iodophor, which is an iodine based product, is different.
Both of these products have different shelf lives once mixed. For StarSan, as long as you keep the pH of the solution below 3, it will continue to be effective.
