Is my hydraflask dishwasher safe?
While hydraflasks are dishwasher friendly, we recommend hand washing in warm soapy water for best results. Rinse well and air dry with the top off. When thorough cleaning is required, hand wash with diluted vinegar or baking soda. We also recommend gently hand washing our caps. Bleach (or any chloride containing detergent) or ammonia should not be used on stainless steel.
