I do what Hammy does. I hose it off and drop it into the boil about 15 minutes before the end. I then collect about the first 10 gallons or so of the really hot water coming out of the chiller at the beginning of the chill in a rope tote. When I'm done chilling I drop the chiller in the hot water in the rope tote, rinse it with a hose, blow the water out, and hang it to dry.
