I had mixed up a gallon of Chlorhexidine solution about a month or so ago and still have about 3/4 of the gallon left. Since I really dont use alot of the stuff, I was wondering if chlorhexidine has a certain shelf life once it is mixed. I would hate be cleaning but 'not really cleaning' if the solution is no longer good. Just a random question I came up with while cleaning some enclosures today

ha ha....Where you at Matt?
