Not sure how many folks use their CO2 system to pressure clean their beer lines but I have (3) Micromatic 1.3 Gallon Cleaning Kits for D systems for sale. Basically you pour cleaning detergent in the bottle, connect to your normal keg tap (you leave the CO2 and Beer lines connected to the tap) and the CO2 pushes the cleaning fluid through the tap, through the beer lines and out your faucet into a bucket. This saves all the hassle of pulling the hoses off the tap and then reverse flowing detergent through the faucet shank. I ended up with these as part of a kegerator purchase and don't see the need to keep this many. They will come with one 16 oz container of Micromatic's Clean Flo powder. This kit sells on Micromatic's website for $102.95. I'm asking $50 a piece plus shpping. Here is a picture of the kit. Let me know if interested.
