How to Dry a Water Bladder

Got a hydration reservoir that never dries out? It could be a breeding ground for mold and mildew. You can avoid the funky smell, gross taste and health risks of a moldy water bladder by making sure it dries out between every use. A lot of people end up dealing with a funky smell or taste simply because they aren't sure how to dry a water bladder. It's pretty easy once you know how; just follow the steps below!

Here's a step-by-step guide on how to dry a water bladder

1. After rinsing the hydration bladder, dump all of the water out and drain the hose by squeezing the mouth piece and lifting the reservoir higher than the mouth piece.

2. If you can reach your hand in the fill opening, dry excess water with a paper towel or a clean dish towel. If you can't fit your hand in, no big deal, it will just take longer to dry completely.

3. Leave the cap open and hang the reservoir to dry. Many CamelBak hydration reservoirs come with hidden dryer arms that keep the reservoir open when it's hung upside down. If your water bladder doesn't have dryer arms, make a water bladder drying hanger, as seen in the picture below. Use a saw to cut the hanger near the top on one side. Cover the cut ends with tape, so they don't puncture the bladder. Hang the water bladder on the hanger.

4. Drape the hose around the top to keep it from dragging.

5 Hang in a cool, dry location

6. Let the bladder dry completely before storing it.

Now that you know how to keep your water bladder dry, you won't have to worry about getting rid of an off taste or moldy residue. You can just fill your reservoir with water, tuck it in your pack and head out for your next adventure.

I just store mine in the freezer. No mold, no mildew.

I hang it upside down, wipe down the remaining water that stays at the bottom (top) below the hole, and then insert a piece of cardboard from paper towels, toilet rolls, etc to prop it open while it dries completely.
