Before starting to use it, rinse the bottle and cap with detergent and warm them up with warm water. We do not recommend washing the bottle in the dishwasher, as this may impair the effectiveness of the insulation capacity. Do not place the bottle in the freezer because it is insulated, you will not be able to cool the water this way, instead place ice cubes in the bottle if you want cooler water. Do not use strong chemicals such as bleach or chlorine on or in your bottle as your bottle may begin to rust. The bottle will easily accompany you wherever you go to keep your drinks cool and warm.
