More like months. StarSan suposedly gets cloudy when it gets old. As long as it is clear, its still good. I usually mix it up in a 2.5 gal water jug and then use that to fill up spray bottles and sanitize kegs, buckets, ect.

You could theoretically swirl it around a clean bucket for example and then put it back in the jug for later use, but since its cheap I usually don't. I keep the starsan jug "fresh".

I've heard that some water will make Starsan cloudy immediately with no bad effects.

I make up a large batch that I keep in a 5 gallon water bottle. Covered with foil for over a month. I have just topped it up on occasion.

I keep a spray bottle handy. Its useful for spritzing all the small pieces.

Ph strips will tell you if it is still good.

Put it in a spray bottle and spray everything Star san really only needs 10 seconds of contact. The spray bottle. Conserves and its really easy to use Stays forever as long as the ph is under 3. Just spray some on ph paper before you spray and equipment

I've wondered about this question myself. I discovered this video on youtube which is very helpful:

The ph test strips look like a good idea, but I haven't purchased any yet.

I always have two sets of ph strips: one the 4.8 - 5.8 range for my mashes, then I also have one in the 2.5-3.5 range that I use to test my star san. If the pH is above 3, I add a bit more. After a while of this, it starts to get a bit soapy and sticky.

I typically keep a batch of star san for 3-6 months.
