Using your CamelBak Podium Chill is a breeze. First, open the high - flow, self - sealing cap. Squeeze the bottle gently, and you'll get a good flow of cold water. When you're done, make sure to lock the cap to prevent leaks. As for maintenance, you can separate all the parts easily. Wash them thoroughly with mild soap and warm water. Don't use harsh chemicals as they might damage the TruTaste™ polypropylene. Remember to dry all parts completely before reassembling. Also, keep your bottle in a cool place when not in use to maintain its performance.
