Lifeline recommends hand washing your stainless steel water bottle with a non-abrasive dishsoap. For a more thorough cleaning, add 1 teaspoon white vinegar OR baking soda to the bottle, fill 3/4 of the way with warm water, close and gently shake. Rinse thoroughly and let your bottle air dry with the cap off.
