I was messing around today with a few flavors, and came across a mixture of two that I REALLY like. Flavor and vapor production are incredible. My question is, what can I store this in? Storing meaning overnight. For example if I want to clean my tanks but save the mixture, can I sterilize something with alcohol, rinse, and then store? I know improper storage over long term is bad, but I am talking one or two days. Any tips would be great.
