Using your Stelton Keep Cool drinking bottle is a breeze. Simply unscrew the cap and fill it with your favorite hot or cold beverage. You can take it with you on hikes, to the gym, or just for your daily commute. To keep it in top condition, wash it regularly with mild dish soap and warm water. Avoid using abrasive cleaners as they may damage the powder - coated finish. When storing, keep it in a dry place. If you're not using it for a long time, make sure it's completely dry inside to prevent any mold growth. And remember, if you have any issues, you can take advantage of our 30 - day return policy.
