If you feel that your bottle needs a thorough cleaning, wash it with 1/4 cup apple cider vinegar, 3-4 tablespoons of baking soda and hot water. You can even leave it to soak overnight for stubborn stains or odors. Please do not use bleach or chlorine cleansers since the naturally protective finish of stainless steel, while very durable, can be damaged by these ingredients. We DO NOT recommend the dishwasher as it will compromise the vacuum seal insulation and void your warranty.
