So i have a SS conical fermenter.. and theres this little piece that sits on the lid.. with a piece of foam stuff that sits under it ... i unscrewed the bar that holds the lid down.. tilted the lid up.. and lid slipped and the metal piece and foam fell into the beer! i havent sanitized either of the pieces.. in a long time ( figuring that they wouldnt ever touch the beer heh. So my question is.. if i start to smell any odors of see and stuff developing.. is there anything i can do to try to save the beer?
