Here are some steps you can take to make sure your Camelbak reservoir enjoys a long and clean lifespan: 

• Completely dry your reservoir out immediately after every use.  Take the reservoir apart (bite valve from tube, tube from reservoir) to speed this process.  Simply letting each part air dry can save hours of maintenance.  Blow air through the tube to make sure there’s no water left.  Hang your reservoir using a reservoir dryer or by draping the tube over a hook.
   

• The Camelbak cleaning kit includes a reservoir dryer, small brush for cleaning the tube of your reservoir, large brush for inside the reservoir, and two cleaning tablets.
   

• Over time, you may notice some small black spots living in your reservoir or tube.  Have no fear.  Simply pop in a Camelbak cleaning tablet, let it sit overnight, rinse it out and continue using your reservoir.  If the black spots are stubborn, put a teaspoon of a baking soda/lemon juice mixture in your reservoir and let it sit overnight.  Rinse it out in the morning and check your status. 

Happy trails!
