how often should you clean beer lines in a pub?
If you are using your beer line regularly, it is advised to clean your beer lines every two weeks, but once every six weeks should suffice at a minimum. It may be most convenient to simply clean and sanitize your lines between each keg you hook up to your draft system.
It all depends on the age of beer lines
If older than 10 years you should consider cleaning for one week otherwise two weeks is most appropriate. Consider cleaning with acid to remove any beer stones. For regular clean, use an alkaline solution to remove bacteria.
if the system is new with triple layer tubing, then 3-4 weeks is ok.
