Here are some simple steps to follow to make sure your cooler is clean and ready to receive our high-quality water.

Suggested Materials:

  • Clean rubber gloves
  • Lint-free paper towels or other clean, dry lint-free cloths or towels
  • Clean dish-type scrub brush, with a long handle to help you reach the bottom of the reservoir
  • Plastic scrubbing pad. Never use soap or detergents, steel wool, or other abrasives on your reservoir!
  • Measuring spoon, one teaspoon volume.
  • 2-gallon pail
  • Unscented household liquid bleach.
  • Clean 1 gallon container filled with bottled water

**The most convenient time to clean your cooler is when a bottle is empty!


  1. Unplug the power cord.
  2. Remove the bottle. If there is still water in the bottle, make sure that you cap or cover the bottle for re-use.
  3. From the COLD-FAUCET drain all water from the cooler into a bucket. Discard this water.
  4. Remove the cooler top. If the cooler is equipped with a no-spill device, it may need to be removed first. Look in the reservoir to see if there is a removable baffle. If there is, remove it.
  5. If there is water remaining in the cooler, drain it out. If the reservoir has an ice ring in it, add hot water to melt the ring and completely drain the reservoir. Do not spill water outside of the reservoir into the interior of the cooler.
  6. Prepare a cleaning solution in the calibrated container by adding one teaspoon of unscented household liquid bleach to each gallon of water.
  7. Wearing clean rubber gloves, immerse the lint-free towel and/or scrub brush into the cleaning solution. Squeeze all excess cleaning solution from the towel and aggressively clean all surfaces of the reservoir interior. Do not pour the cleaning solution directly into the reservoir.
  8. Rinse the reservoir: Carefully fill the reservoir, with bottled water from the 1-gallon container, to ½ inch from the top of the reservoir. Completely drain the rinse water from the reservoir through the cold faucet.
  9. Use the same cleaning solution brush and/or cloth to clean the baffle, the cooler top, drop receptor and faucets. If your cooler is equipped with a no-spill device, it should be cleaned with the same cleaning solution. Take care not to get the air filter wet. Use the clean 1-gallon container filled with bottled water to thoroughly rinse these parts.
  10. Wearing the rubber gloves, re-install all parts: baffle, cooler top, faucets if removed and no-spill device (if equipped).
  11. Place a bottle back on the cooler and drain 2 cups of water from each faucet, or until there is no evidence of a chlorine taste and/or odor. Dry all spilled water on the cooler and the floor.
  12. Plug the cooler back into the electrical outlet. Allow 45 minutes for the water to reach the appropriate temperature.

If you follow these steps, you’ll now have a clean cooler. You’ve now taken an active role in preserving the quality of the equipment you use to dispense your high-quality bottled water.
