I recently noticed that my keg plug/brush is smelling like vinegar. I have soaked in oxyclean and pbw and it seems to not stay as clean as it did when new(it gets soiled much quicker). My kegerator is on my back porch and without plugs the various bugs of south Georgia would be crawling as far inside the faucet as they can get. So any suggestions on how to keep the plug clean or what type of plug to use that won't get as nasty? Taking the kegerator inside is not an option, just don't have the room. Thanks in advance!
