I saw some Youtube dude saying he used his Star San solution over and over. He fills a keg with it, pumps it out to fill the keg with CO2, and sends it to a new keg. Next time he has to keg something, he does the same thing with the same batch of solution, moving it from keg to keg. I did this a couple of times, but I'm thinking of pouring the solution out tonight. It costs around 75 cents to make 5 gallons of solution, but I am concerned about using dead sanitizer and ruining a batch of beer.
So does anyone have any FACTS about how many times you can pump Star San into clean kegs without risking infection?
