If you purchased your Iron Flask through our website and it was damaged during transit, please send us an email at If you purchased your bottle through Amazon, please request a refund from Amazon and state the reason as “damaged during transit.”

What Is Our Warranty On Accessories?

We are glad you asked! ALL of our products come with lifetime warranties.

Lid Sets: Our spout and straw lid sets come with a lifetime warranty against leakage or other malfunctions including "bad water flow" which is when straws let out air or bubbles.

One Important Note: What Our Warranty Does Not Cover

Please remember that our lifetime warranty only covers manufacturing defects. Our warranty does not cover damages caused by improper use, by cleaning practices, by any modifications, or by wear and tear. We will provide an exact replacement for your bottle or accessory when a warranty claim is approved.

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
