Activate Your Lifetime Warranty

Your Iron Flask comes with a lifetime warranty against manufacturing defects. We know you will love your Iron Flask and are committed to your 100% satisfaction. We will provide a replacement or issue a refund if your Iron Flask has any manufacturing defects.

Iron Flask Lifetime Warranty Guarantee

Iron Flask believes a good bottle should last a lifetime, and we want to make sure yours does! That’s why we offer the Iron Flask warranty and 100% customer satisfaction guarantee.

Our warranty is included with all Iron Flask products to protect against manufacturing defects. Why? Because our priority is to ensure customer satisfaction and confidence in the durability of our products. The Iron Flask guarantee of high quality sustainability products means you can expect an iron Flask replacement or refund if your purchase has any manufacturing defects.

What Does Our Lifetime Warranty Cover?

When you purchase a lifetime warranty water bottle product (including tumblers and accessories), you can rest assured that it covers manufacturing defects such as leakage, insulation flaws, or rattling noise. Please note that any damage caused by misuse, wear and tear, and any modifications does not fall under manufacturing defects in the Iron Flask warranty. Warranty claims are only approved if the product is purchased from Iron Flask Group LLC or an authorized reseller. Our lifetime warranty does not cover donated products. If your Iron Flask was received as a gift, then you would have to get the order number used to purchase the gift in order to register for the lifetime warranty.

With a lifetime warranty water bottle from Iron Flask, your purchase is protected even before it gets to you — we’ll cover any damage during shipping. We understand that it's not ideal to eagerly await your new Iron Flask only to find it damaged upon arrival. If your Iron Flask was purchased through our website and then damaged during transit, please send us an email at support@ironflask.com. If you purchased your bottle through another seller such as Amazon, please request a refund from Amazon and state the reason as "damaged during transit."

You will be asked to ship your warranty product back to Iron Flask at your own cost for our review prior to us shipping you a replacement product.

Does the Warranty Apply to International Orders?

If you have warranty questions about an order shipped outside of the U.S., please contact us at support@ironflask.com for international order warranty details.

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.

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.

Protective Boots: Our silicone protective boots include a lifetime warranty against manufacturing defects. The most common issue you might encounter is the boot not properly connecting with your Iron Flask or coming off easily. Please make sure to order the right size boot for your bottle.

Paracord Handle: Our handles come with a lifetime warranty against manufacturing defects and malfunctions.

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.

We make it easy to register your Iron Flask. Simply provide your name, email, where you purchased your product, and order number.
