How Should I Care for My Iron Flask?
Iron Flask products require little maintenance. However, there are a few tips you need to keep in mind to enhance the durability of your bottle, lids, and accessories.
Before Using Your Iron Flask for the First Time
Hand wash your Iron Flask, lids, and straws (if applicable) with hot, soapy water.
How to Wash Your Iron Flask and Accessories:
The best way to keep your Iron Flask clean and in excellent shape is to wash it by hand with warm, soapy water.
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 cleaning brush. Your Iron Flask should not develop any rust, stubborn spots can be removed using the cleaning method mentioned above.
What about lids and straws? Lids are dishwasher safe. We also recommend cleaning your lids and straws with a gentle, size appropriate brush.
What Not to Do with Your Iron Flask:
Please do not put your Iron Flask in the dishwasher or wash the exterior with hot water. Exposure to high temperatures can compromise the powder coat which can cause the vibrant color of your bottle to fade.
Do not place your Iron Flask in the microwave or the freezer, this could cause damage to your appliances and your bottle.
Keep in mind that Iron Flask bottles are insulated to maintain the temperature of the liquids placed inside them despite external temperatures. These beautiful bottles truly defy the elements. This also means that placing your bottle in the freezer has no effect on its ability to maintain your beverages icy cold.
Do not use bleach or other chlorine cleaners on your Iron Flask products. These chemicals are strong and will damage the stainless steel components of your bottle and accessories.
How Do I Track My Order?
Once your order is shipped, we will share shipping and tracking information via email. You can then use the tracking number to get updates from the carrier. If you have questions about your order status please email us at support@ironflask.com
Do You Ship to P.O. Boxes?
We do not ship to P.O. boxes at this time.
