Are they just being cautious or is there a real concern with this? Any personal experience good or bad?Question:
Can Star San be stored in a stainless steel corny keg in a 300 ppm solution or will the acid damage the metal. Thanks
Answer:
Any liquid will damage the metal over a long period of time. Star San will not hurt the metal overnight, but if you leave this solution in the keg for multiple months, it could start to harm the metal. The best advice is to only make up what you need, when you need it. You should clean all equipment after you use it, and then sanitize the equipment just prior to brewing.
