I have a few kegs in my home bar (homebrew) and haven't cleaned the lines as of yet. I don't have an empty keg to fill with Oxyclean or BLC or PBW to force cleaner through the lines via CO2. I had a few questions for you. How much cleaner would I need to use to clean the lines (cobra taps w/ 4-5' of beer line)? I was thinking of getting a new 1 gallon pump sprayer and fitting it with a ball-lock liquid out post to hook up my QD with line and tap to, pump up the sprayer, open the cobra, and let it rip into bucket below. Close off the tap mid way through to let it soak inside for 10 mins or so, then reopen and let it go again. Rinse with clean water the same way. Then run StarSan through it before hooking back up to the keg for consumption. Thoughts? Would 1 gallon be enough? Anything yall see that would go wrong with this? My kegs last about 8 weeks or so at a time depending on the beer (3 kegs, plus wilds and Imperials in bottles).
