The best way to care for your reservoir is to clean and dry it after every use, especially if you fill the reservoir with anything other than water. However, if a reservoir has not been cleaned after every use, and mold or discoloration develops:

  1. Use hot water and a CamelBak Cleaning Tablet. (Or use 2 tablespoons of baking soda or bleach instead of CamelBak Cleaning Tab.) Mix the solution inside your reservoir and elevate the reservoir above the tube and Big Bite Valve. Pinch the bite valve, allowing the solution to flow into the drink tube and fill the bite valve.
  2. Let the reservoir and cleaning solution sit in the reservoir and drink tube for about 30 minutes.
  3. Wash the reservoir with hot water and mild soap. Be sure to completely rinse away the cleaning solution in the reservoir and drink tube before using again. You can also use CamelBak brushes from our Cleaning Kit to scrub your reservoir and drink tube. Brushes are the best way to ensure you are scrubbing all of the areas of the reservoir clean.
  4. Once the reservoir is clean, be sure to air dry overnight so no moisture is trapped inside, which can cause mold to grow.

These steps will make your reservoir safe for use. If there are still spots left behind, these are permanent mold stains that may not be removable. However, your reservoir is still safe and usable after you’ve cleaned it.

Comments about CamelBak Antidote® Lumbar Reservoir 100 oz/3.0L:

I use this to go on day hikes. The large reservoir keeps me going for hours. It also stays cool during the hot days.
My only draw back is there are no drying arms from keeping it from getting mold growing
Overall a great product.

    Comments about CamelBak Antidote® Lumbar Reservoir 100 oz/3.0L:

    I go for rides that last 6 to 10 hours. I have a herniated disk in my low back, and all other reservoir configuartions have caused me pain, limiting activity. Lumbar Antidote does not cause pain. It also helps with balance, and fatigue. I just wish there were more packs configured for it.

    Don't you dare get this thing for backpacking, what the heck kind of water container thingy doesn't have a lock option?!? Realized the design flaw after waking up in a pool of my own sorry because I accidentally fell asleep on the hose thing.
