So I just finished upgrading my kegerator to four taps. I sanitized all my new beer and air lines. But, I didn't even think about cleaning or sanitizing the new CO2 distribution block until after I hooked everything back up. I'm not sure how I would even clean it if I tried. Does anyone clean/sanitize these kind of parts? I'm not concerned about ruining the beer currently in the system. I'm just concerned there might be some nasty stuff (chemicals, metal shavings, etc.) in there from manufacturing that has now been blown into my beer. Does anyone think I have a real concern here or am I just being paranoid?
