To clean your BlenderBottle, first, remove the lid and the blender ball if it has one. Then, rinse the bottle and the lid with warm water. You can use a soft sponge or brush with a little bit of dish soap to scrub the inside of the bottle and the lid. If the bottle or lid is particularly dirty, you can soak it in warm soapy water for a few minutes before scrubbing it. Finally, rinse everything with clean water and let it air dry.
