1. Empty out the reservoir and tube.
2. Fill the reservoir with warm water and add a disinfectant or homemade cleaner (see above), shake well and leave it next to the sink (with the drinking tube in the sink) so the water and cleaning solution can drain out. Let it soak for about 5 minutes if you used a cleaning tablet, or 10 minutes if you used the homemade cleaner.
3. Empty out the bag and fill it with warm water and a few drops of dish soap.
4. Using the brushes, scrub the interior of the bag and the drinking tube.
5. Clean the outside of the tube too.
6. Rinse well to avoid any unpleasant taste, and dry.
Using a clean, dry cloth, wipe your reservoir or let it dry upside down on a hanger. It is important for the bag to stay completely open so that air can circulate. Blow into the tube to drain any excess water before hanging it up to air dry.
