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 Mil Spec Antidote® Reservoir 100 oz Long:

Got this with my new 37l Motherlode pack and used next day up Snowdonia, Wales UK. My husband was jealous of this hydration pack and said it put his (other brand) reservoir to shame. Easy to use, more features than other brand reservoirs, amazing quality. Really pleased with this product looking forward to using it on our regular treks. P.S. equally over-the-moon with my new Motherlode, thanks Camelbak!

    Comments about CamelBak Mil Spec Antidote® Reservoir 100 oz Long:

    The resevior is awesome. It comes with the 2013 H.A.W.G., which I received as a gift. After seeing the other review, I had to set the record straight. This thing does NOT leak, if you close it properly. There is a gasket that is hooked onto cap apparatus and it WILL leak if you do not take care to make sure the gasket is in it proper position. So yeah, if you're not a monkey, you should have no problem closing and sealing your resevior. I made the mistake once and immediately saw what I did wrong.

    One feature I love is a shutoff valve that activates when the tubing is detached, making it much easier to throw in the fridge or freezer the night before a long hike. I don't think they recommend putting it in the freezer, but in Phoenix, the R.O. water from the tap is warm, so its never frozen the next morning, just a few ice chips.

    Another great feature is the mouthpiece and on/off valve near the mouthpiece. There is a cap that prevents the desert floor from getting my mouthpiece all dirty (I've forgotten about it and dirtied up my mouthpiece a bunch of times). And the valve ensures safe transport without leaking.

    Not so important, but I also really like the insulated tubing. If it does nothing else, at least it just makes it look much better quality. A friend of mine has a different brand and his tubing is all yellow and discolored from the sun. I much prefer my camelbak.

    Overall, I would recommend the H.A.W.G. with this reservoir to anyone looking for an awesome day pack. The bag also has plenty of webbing so you could use it for a weekend pack if you wanted to strap on some extra pouches (recommend maxpedition 5x7x4 and 5x7x2 general purpose pouches), and a tent and bag.

      • Leaks At The Cap

        The cap leaks. I sent it back and they sent me a new one and it leaks at the same place. Terrible design.
