How do I clean my Platypus bottle or reservoir?
Use hot, soapy water and rinse thoroughly with hot water. For tough cleaning jobs, add 1/4 cup of baking soda to 3/4 cup of water per liter volume of your bottle or reservoir and shake for 30 seconds. Add 1/4 cup lemon juice, shake 10 seconds, and vent by loosening cap away from face. Repeat shaking and venting three times. Expel as much air as possible, cap bottle, and allow to soak 20 minutes. Rinse three times with hot water. Caution: When adding lemon juice to baking soda, effervescence occurs and will cause pressure to build in a capped Platypus product.
How do I prevent the water in my hydration system from freezing in cold weather?
Using our Bite Valve & Drink Tube Insulator is an easy solution to deter freezing. Additionally, to help prevent the water in the reservoir from freezing, start off the day with warm or hot water in the reservoir, then pack your extra clothing layers around it. To help keep drink tubes and bite valves from freezing up, sip often to maintain flow, and, after you’ve finished drinking, blow any residual water back into the reservoir. Also, even if you are using the Bite Valve & Drink Tube Insulator, it still helps to keep as much of the drinking tube covered as possible, such as routing it inside a pack, strap, or jacket.
