Love Your Iron Flask Inside and Out

The majority of questions we receive are related to the care of our bottles. Remember that the beautiful powder coat on your Iron Flask does not do well in the dishwasher. Here are a couple of tips on how to properly care for your favorite bottle:

  • Use warm soapy water to wash your Iron Flask inside and out
  • Never put your Iron Flask in the dishwasher, the wash process might affect the powder coat on your bottle
  • For a little extra cleaning power, put ¼ to ½ cup of distilled vinegar inside the bottle and gently swirl it around. Let it sit for 5 to 10 minutes. This quick tip helps remove spots inside the bottle. For hard to remove spots mix 3 teaspoons of baking soda with a little bit of water and use a gentle brush
  • What about the lids? Lids are dishwasher safe. We also recommend cleaning your lids and straws with a gentle, size appropriate brush.

The Iron Flask warranty also includes customized Iron Flask products. Please note that if you need a warranty replacement for a custom water bottle or tumbler, your replacement cannot be customized. For custom products under the Iron Flask water bottle warranty, you will be asked to ship your warranty product to our team. Once reviewed and approved, the Iron Flask team will ship you the replacement.
