This is what I did when I used a Camelbak. Fill the bladder with water, add a tablespoon of bleach, drain some water through the bite valve to pull some bleached water into the hose, and let it sit overnight. Rinse thoroughly and that's that.table spoon of bleech diluted.
+1 bottles who wants a hot pack in the summer anyways. When i did use bladder always stored it in freezer in the summer months. Cleaned with bleach and/or peroxide when needed using kit brushes.
