I usually reach down in with my arm with a single cotton ball, worked good for years. Then I started working out, now my arm is as big around as a coffee can. Won't fit. Then the cat said "use the other arm". I did. Then the skinny arm noticed how big the other arm was and swelled up with jealousy bigger than the other arm. Now I'm really screwed! Then the cat said he read about a carboy cleaner give away on HomeBrewTalk.com. He is a smart cat.
