Hi, I'm pretty new with star san and I'm having an issue with the milky look of the product. I use 1/2 oz in 2.5 gallons. Everything is fine the first day, but 48 hours after, the liquid turns milky. I tried to make another batch, same thing. I don't have phpmeter to check it. Is it possible that my star san is bad after only 48 hours? I store it in plasic bottles (used for acid products before but well rinced).
Thanks for your help!
