Oxyclean cleans my kegs, they are easy. Once you learn how to take the rings off and put them back where you can get them off easier the next time, they are great. Cornie's have two different styles of fittings, which becomes a mess when you get a keg that requires a different one than you have. I am not knocking Cornie's, just trying to say that Sanke's aren't any harder to clean or use, and they are readily available for a deposit. Don't modify them or anything and you are just borrowing them. I turn my kegs in for deposit on another one for parties all the time. Then I have a fairly new keg to reclean and use a couple of times until someone else is having a party. I make a little bit by charging them for gas and tap setup, but I drink for free and get a keg for my home brew.
