Can I put my Thermos flask in the dishwasher?

Asked 6 months ago
No, it is not recommended to put your Thermos flask in the dishwasher. Thermos flasks are designed with a double-wall vacuum insulation that can be compromised if exposed to high temperatures and harsh detergents. This can lead to a loss in insulation performance or even damage the flask. It is best to hand-wash your Thermos flask using warm soapy water and a non-abrasive brush. Rinse it thoroughly and allow it to air dry before storing it. This cleaning method ensures that your Thermos flask remains in optimal condition and continues to provide excellent thermal insulation for your beverages.
