My latest keg finally emptied last night, so I was thinking, I have never taken the whole thing apart to clean it. Also, this might be a good time to take a look at the beer line and see if shortening it up might help with the foam I get on the first pour of the day. My ritual up to now was I would fill the keg with Alkaline Brewery wash and run it thru the lines and tap like I am pouring a beer. I do this for about 3 to 4 gallons and they switch and clean out the keg with warm water and flush the lines that way. I tried to take the tap apart once, but got scared as I could not get the stem out without forcing so I quit. I am guessing as long as the cleaner hits the same spots as the beer then I am ok, but just kinda curious what you all do. Also, after I am done with that, I usually run StarSan thru it the same way. I get alot of foam out of the tap, but heck, that must mean it's doing it's job, right?
As far as the foam issue, my line is about 5 feet long I believe, and it runs up from the keg, thru the little freezer area and up to the tap. My tower is pipe that you would buy at home depot, and it has an insulation tube in it like you would wrap pipe on your water heater or outside pipe to keep it from freezing.
Anyway, any feedback would be most appreciated.
