A buddy of mine just bought a bar and I found 7 old, nasty coke kegs in the basement. He was going to send them to the scrap yard, so I took them home to clean. They all apear to be in decent shape, and cleaned up pretty well.
I have taken them all apart and have the lids, posts, and dip tubes soaking in oxyclean, then when I can reassemble them, I will use new O-rings, then fill with oxyclean to clean the insides.
SWMBO has come to terms with the expense of brewing and bottling 5 gallon batches, but is not thrilled at the idea of me spending money on kegging related equipment. She is also not excited that I have all of these kegs taking up space in our small house. My solution is to potentially trade 3 or 4 of these for different beer-related equipment.
What i would be interested in:
I am in the Pittsburgh area and would prefer to not ship these things, but drop me a line if you're interested.
