I clean my beer lines and taps every 2-3 weeks Chester. I don't always take the taps apart but I do run a recirculation of PBW with a pump, usually run for approx 30 minutes then cold water flush and then cold sanitiser recirculation and leave the sanitiser in the lines until I want a beer. Normally only about 10 minutes! I always spray the tap with sanitiser after pouring a beer and plug the tap with one of those little brush things from the brew shop. My keezer is out under the pergola so that keeps the vinegar flies away.
