How to Clean and Dry a Hydration Backpack

Overview
On the trail, a hydration backpack can provide the hydration required during a long hike. Mold and bacteria can begin to grow if the backpack is not cleaned promptly after leaving the trail. Proper cleaning can be difficult but is essential to prolong the life of your backpack. Many companies offer special tools and cleaning kits that make the process much easier.
Step 1
Remove the reservoir, or bladder, from the backpack and fill it with mild liquid dish soap and warm water. Drop a cleaning tablet into the soap solution and allow it to dissolve.
Step 2
Scrub the inside of the reservoir with the brush until all surfaces have been touched. This will break up any bacteria and allow the cleaning tablet solution to further clean the reservoir walls.
Step 3
Rinse completely and drain the water several times until the water runs clear and free of soap. Soapy water will not taste very good the next time you are on the trail.
Step 4
Open the neck of the reservoir, insert the reservoir dryer, and hang upside down to allow drying. The reservoir dryer keeps the reservoir open over time and allows the water to drain out.
Step 5
Use the tube cleaning brush to clean inside the tube. This can be a difficult place to reach but is essential for a completely clean bladder.
Step 6
Place the pack in the clothes washer on the gentle cycle and tumble dry. Most packs are durable enough to handle the washer but consider hand washing with cold water and mild soap if you desire.

Tips
Use baking soda to remove the odors remaining after cleaning.

Warnings
