Best Keg/Beer Line Cleaner

What do you guys use to clean kegs and beer lines? Powdered Brewery Wash? Do you fill the lines and let them soak?

Plain water works. Even better with a little Oxyclean. I don't let it sit too long before rinsing.

I normally just use oxyclean and water and rinse well. I've noticed lately, though, that I've got some beerstone in my lines and kegs. I used BLC last time and it worked great!

I'm going to do some "spring cleaning" this year, and get new lines and do a very thorough cleaning of my kegs. My lines are about 3-4 years old, and it's probably cheaper and easier to just replace them them try to clean all the beerstone out. I have to take apart my faucets and shanks, too.

Yeah, I let some tooobing soak too long in Oxy and it ended up with some kind of mineral scale on it. I've got tons of Oxy, though. What concentration do you guys use?

I just make a pbw solution at double strength. Run it through the line, let it sit in the line 10 min , flush out and sanitize with star San solution.
