would i be able to safely use a keg and beer gun for clean regular beers after a sour beer was in there? im assuming with the beergun as long as i use dedicated lines for sours the actual beergun should be no problem to clean and sanitize, kind of a silly paranoid question but just wanted to get your thoughts, i thought if i would soak it in pbw then fill it with boiling water then star san, would it be better to just keep this a sour only keg?
