Can I put my Klean Kanteen® on a stove?
In a pinch, single-walled Kanteen® Classic and Wide bottles with the Brushed Stainless finish can be placed on a fire or a stove as long as you take the cap off. Do not do this with a colored bottle, as it will damage the paint. But it’s VERY important that you know what kind of bottle you have because this is absolutely NOT an option with an Insulated Kanteen®. Heating a Kanteen® Wide Insulated will damage the bottle and voids the one-year warranty. It’s pretty easy to tell what kind of bottle you have, even if you’ve had your bottle so long the logo’s worn off. Insulated bottles only come in the wide-mouth design, so if you have a Classic, a bottle with a long neck and a small rolled lip at the edge, you have a Classic. Insulated bottles also have a separate, extra shiny piece at the bottom and come in different sizes (12oz, 16oz, and 20oz) than the single-walled Wide bottles (12oz, 18oz, 27oz, 40oz and 64oz).
