So when i bought my kegerator used, i sanitized everything and ended up leaving some iodophor/water in the beer line for about a week. now i have an obnoxious situation. my first pour tastes like iodophor. if the beer gets to sit in the line for any significant amount of time, it tastes like iodophor. what can i run through my beer line to get the crap taste out of it? id like to try to avoid replacing the line if possible, although i should probably put a longer one in there anyway. thanks.
