Separate the pieces and rinse them all (thoroughly, i.e. for a minute or two) under hot tap water. Then give the tube parts several vigorous shakes, like you're cracking a whip. Store upright (I put mine in a bucket) in a warm area to allow the water droplets to evaporate out of the tubes. In a day, they should be mostly or all the way dry. Shake them out a couple times during the drying process, to thin out the water droplets, it will speed the drying. The idea is simply to dry them quickly before you put them away for storage. I've been using the same siphon tube, and even transfer tubing, for about 7 years now, no problems.
