Learn the best way to clean and dry your HydraPak reservoir to prevent mold and odors, plus storage tips to keep it fresh between adventures.
Quick Answer
To keep your HydraPak reservoir fresh and mold-free, clean it after every use with warm water and mild soap, then dry it thoroughly before storing. For deep cleaning, use a cleaning kit or a mild bleach solution.
Why Proper Cleaning Matters
A hydration reservoir is a closed system, and any leftover moisture can quickly become a breeding ground for mold and bacteria. Regular cleaning not only keeps your water tasting fresh but also extends the life of your reservoir, saving you money in the long run.
The wide opening on the Velocity™ 2L makes it easier to add ice and reach inside for cleaning, which is a practical advantage when you're trying to scrub away residue.
Common Cleaning Mistakes to Avoid
Many people use harsh detergents or put their reservoir in the dishwasher, which can damage the materials. Stick to mild soap, warm water, and a soft sponge or brush.
Another common mistake is storing the reservoir while it's still damp. Even a little moisture can cause mold, so always dry it thoroughly before putting it away.
Step-by-Step Cleaning and Care
- Rinse immediately after use: Empty any remaining water, then rinse the reservoir and tube with warm water. This removes the initial residue and prevents buildup. Don't let it sit with water inside for more than a few hours.
- Wash with mild soap: Fill the reservoir with warm water and a drop of mild dish soap. Use a soft sponge or brush to scrub the inside, especially the corners and the tube. Rinse thoroughly until no soap remains. Avoid harsh detergents or bleach unless doing a deep clean.
- Deep clean to remove mold or odors: If you see mold or notice a musty smell, fill the reservoir with a solution of one tablespoon of unscented bleach per liter of water. Let it soak for 30 minutes, then rinse extremely well with clean water. Always rinse multiple times to ensure no bleach residue remains.
- Dry completely before storage: Turn the reservoir inside out (if possible) and hang it to dry with the opening open. Use a drying rack or a clean towel to absorb excess moisture. Ensure the tube and bite valve are also dry. Never store a damp reservoir; mold can develop in as little as 24 hours.
- Store properly: Once completely dry, store the reservoir flat or hanging in a cool, dry place. Avoid folding it in a way that creases the material, and keep the tube and valve disconnected to allow airflow. Check your reservoir periodically if stored for a long time.
