Care and Cleaning

Hydration Reservoir Care

NOTE: The ExtremeMist PCS Reservoir is made of TPU drink safe materials. However, periodic cleaning is still required. 

DO NOT use boiling water, as this may damage the reservoir.

Freezing water in the reservoir will not affect the material. Keep air in the reservoir to a minimum, as too much expansion during freezing can damage the reservoir.

Cleaning solutions

Cleaning tablets are available at your local sporting goods store, or online. These are easy to use: Just drop one cleaning tablet into the reservoir, and follow the manufacturer’s directions.

To make your own cleaning solution, you can use:

  • Baking soda for odors (1.5 cups for 2L reservoir)
  • Unscented household bleach for neutralizing bacteria and viruses (1 cap-full for 2L reservoir)
  • For really strong odors, you can add ½ cup of lemon juice
  • Mild dish soap

Recommended cleaning tools

Cleaning Kits are available on our website or at your local sporting goods store. You will need the following:

  • Cleaning brush for the reservoir
  • A small brush on a long cord to run the length of your mist and drink hoses
  • A reservoir hanger that props the reservoir open to let the water completely air dry

How to clean the reservoir

Start by dropping in a cleaning tablet or pouring your homemade cleaning solution into the reservoir. Shake the reservoir, then set it aside and let it soak, rinse out the reservoir with a small amount of dish soap to help remove any remaining solution. Lastly, hang the reservoir upside down with its opening propped open to air dry. See detailed directions below.

Step One: Soaking


1. Fill the reservoir with warm water, add cleaning solution, close the top, and shake it for approximately 30 seconds.

2. Leave the reservoir, tubes, and nozzles to soak for approximately 20 minutes. (If using tablets, follow the instructions for saturation times).

3. Raise the reservoir above the bite valve and squeeze the bite valve to allow gravity to force water through the drink hose.

     - If using the ExtremeMist PCS, aim the PCS mist nozzle away from yourself and turn on the PCS for a few moments to allow solution to run through the misting hose and nozzle. Then set it aside. (Exercise caution not to spray on your clothes if using a bleach solution).

     - Drain the system. Be sure to squeeze the bite valve and turn on the PCS again to drain the water from the tubes.

Step Two: Rinsing


1. Once again fill the reservoir with warm, clean water. Add a small amount of dish soap.

2. Use a scrub brush to clean the inside of the reservoir. If you have a hose brush on a long cable, run it through the whole length of the hoses. Remove the bite valve and misting nozzle to make this process easier. (If you don’t have a hose brush, you can tie knots in a thick string and pull it through to accomplish the same thing).


 3. Rinse everything with cool, clean water several times to remove any soap residue.

  • Rinse the bite valve and drink hose by raising the reservoir up and allow water to flow through the drink hose. Rinse out the misting system by turning the PCS on again to allow fresh water to flow through the system.

Step Three: Drying


1. Now that you have all the pieces disassembled and rinsed, shake as much water as you can from the reservoir. Take the hose without the bite valve attached outside and whirl it around to let centrifugal force help to remove the excess water.

2. Remove the mist elbow, and dry the PCS hose the same way as the drink hose (by depressing the quick disconnects to remove from the PCS unit). Remove the small PCS hose as well to allow it to air dry. Lastly, take the PCS itself and vigorously shake out any residual water, then set it aside to air dry.


3. Hang your reservoir upside down to dry, with the opening propped open. If you purchased a cleaning kit, most come with a reservoir hanger that holds it open to allow air to get in (If you don’t have this hanging dryer kit, use any clean utensil - such as a kitchen whisk - to help spread the reservoir apart so it can dry properly).
