Can I put my Thermos flask in the dishwasher?

Thermos Brand generally advises against putting their flasks in the dishwasher. While some components of a Thermos may be dishwasher safe, the high temperatures and harsh detergents found in dishwashers can potentially damage the vacuum insulation or other parts of the flask. It is recommended to wash your Thermos by hand with warm water and mild dish soap. This method is gentle and helps maintain the integrity of the flask while ensuring it stays clean and functional. Additionally, for stubborn stains or odors, a mixture of baking soda and water can be effective. To find specific instructions for your Thermos model, it is helpful to refer to the care instructions available on their website. This ensures that you are following the most appropriate cleaning methods for your particular flask.
