Use hot water and 2 tablespoons of baking soda or bleach. Mix the solution inside your reservoir and hold it up above your head while you pinch the bite valve, allowing the bleached water to run through the tube. You can also use CamelBak Cleaning Tabs.
Let the reservoir and cleaning solution sit for about 30 minutes.
Wash the reservoir with hot water and mild soap. Be sure to completely rinse away any bleach or cleaning solution before using it again. You can also use CamelBak brushes from our Cleaning Kit to scrub your reservoir and tube. Brushes are the best way to ensure you are scrubbing all of the areas of the reservoir clean.
Once the reservoir is clean, be sure to air dry it so no moisture is trapped inside, which can cause mould to grow.
