Follow these steps:

1. Fill reservoir 1/2 full with warm water and mild soap
2. Shake reservoir to mix water and soap
3. Elevate the reservoir so drink tube exit port is at the base and Big Bite™ Valve is below the reservoir
4. Pinch bite valve, allowing solution to flow into drink tube, and through the bite valve
5. After washing, rinse away cleaning solution in the reservoir and drink tube
6. Drain all remaining water. The reservoir is ready to use
7. If storing, air dry reservoir with Reservoir Dryer™ accessory so no moisture is trapped inside
