inside the reservoir and tubing?
After cleaning, you must dry your CamelBak. Make sure all water possible is out of the reservoir. Open the red/blue filler cap and place a wadded up paper towel inside the reservoir then close the filler cap. Use the Bite ValveTM to bite and blow up the reservoir like a balloon. When reservoir is full of air, shake the paper towel around the edges of the center of reservoir until dry. You might have to repeat this procedure one more time to completely dry the inside. To dry the tube, remove the Bite ValveTM and simply hang tube straight down so it can drip-dry.
