Product specifications:

All Platypus hydration products are 100% BPA-, BPS- and phthalate-free, and do not use polycarbonate.

Cleaning:

Hand wash your hydration system using warm or hot soapy water. Using the Cleaning Kit helps access tough to reach places.

For deeper cleaning:

• a. Per litre volume of your hydration system, add ¼ Cup of baking soda to ¾ Cup of water and shake for 30 seconds (e.g., for a 2L hydration system use ½ Cup of baking soda with 1 ½ Cup water).
• b. Add ¼ Cup lemon juice per liter, close and shake 10 seconds, then vent by opening hydration system away from face.
• c. Re-seal hydration system and repeat shaking and venting three times. Expel as much air as possible, close hydration system, and soak for 20 minutes.
• d. Dump solution and rinse hydration system three times with hot water.

Caution: When adding lemon juice to baking soda, effervescence occurs and will cause pressure to build in a closed Platypus product.

In general, it is optimal to prop or hang hydration system reservoirs upright to dry—this allows moisture to evaporate and escape upward.

Drying Big Zip™ reservoirs is easy. First, wipe interior with a dry towel (made easy thanks to the large opening!). Then prop the reservoir open with the SlideLock™ slider and let it all air dry.

Another great way to dry a hydration system is with a plastic bag dryer, widely available at kitchen supply stores and numerous online retailers.
