Here is a nifty gadget for cleaning a CFC and other hoses . I bought it at Menards foe about $2.00 and attach it to a hose connected to laundry tub faucet. I blast hot water through the CFC. It clears out all thd crud in seconds. I then put Aluminum foil over both ends of the CFC and its ready to go for the next brew. No bleach or other cleaners. It's a cheap power washer that could blast the chrome off a bumper hitch.
