my question is this...if I sanitized something (i.e. hydrometer, carboy, whatever...) used it, and then rinse it out very well or rinse off whatever gets on said item, is there any need to sanitize it again?
also, if I store my carboy upside down while all the rinse water drains out of it, will it stay sanitary?
oh and if i sanitize something days before I know i'm gonna use it (i.e. sanitizing tubing as long as i've got a batch of Easy Clean mixed up) is it going to stay sanitary?
