TweetHey, no where on the bottle does it say to keep in the frige but I'm jsut wondering, if I keep pushing air into this bottle everytime I pull some out....how long before the air messes up the sterile water? It doesn't expire until 2009 but still, won't the air mess up the sterile environment? Because I'm just keeping it at room temp right now in a cool dark place (my safe-lol) and just got to thinking. Thanks
