Query do you need a sterile container? Do you wipe the sterile pad over your armpits (presumably without deodorant) or even your crotch or is a facial wipe sufficient? Is there a best time of day, as in the morning when your face, etc. has had hours to build-up oils ? Is it best to do on sweaty skin? Do u , as said, store it at room temperature or do refrigerate or freeze it? Anybody have instructions?
