Default star san shelf life after mixing

Does anyone know how long star san remains an effective sanitizer after it's been mixed up with water? We use a lot of small batches for sanitizing hydometers, spoons, etc and it would save money to just keep a batch of star san mixed up in a pitcher or something and reuse it for these things. But will it still work after a few days/weeks/months, or does it need to be freshly mixed up?

Supposedly it will last forever until the pH of the solution rises above 3.5. If you keep it sealed in a bucket, or a corny, it can easily last over a month.
Once the wind has been broken, it cannot be fixed.

i mix mine with distilled water and store in a 2 litre glass jug.
it has been good for at least a month.
if it starts to go cloudy it is losing effectiveness but you can add more concentrate to reactivate
simplified signature:
beer, wine, cheese in various stages of production
