Re-use of star san after bottling?

[Hawkeye]

Good noon,

I bottled up some beer for christmas gifts last night using my new B3 CPF (pretty sweet tool). I made up some starsan with distilled water to put the CPF in between bottles--keep it clean. So, there were obviously some drops of beer here and there that got in the mix. Is this starsan still good for use today to sanitize a keg, or has the beer dropping contaminated it from being used a second time.

Thoughts?

If the pH is below 3, then it's still good.

BDawg is absolutely right if the pH is below 3 then let it be.

However, if you don't have a method of testing the pH and the starsan solution is not crystal clear, then don't use it. If your starsan solution is in question, ask yourself the question, "Is another 1/2 oz of starsan more expensive then an infected batch of beer?"

Just a thought.
