I don't dry mine at all. On the contrary. I keep a gallon of sanitizing x-Meta(take your choice of Na or K-Meta- so I'll call it x-Meta) on hand. After rinsing and giving it a quick drain, I pour in a cup of sanitizing strength x-Meta. I then take an airlock filled with x-Meta and cap the carboy with it. It fills the carboy with SO2 and keeps it sterile until my next use. When I need it again I just drain the carboy and use it.
