Use straw cleaner for best results. Clean with warm, soapy water using detergents without essential oils or phosphates. Natural detergents often contain essential oils, which can leave residue that's more noticeable to babies. It’s not harmful but can be annoying. Hand washing is preferred, but if using a dishwasher, space items apart. For smells, stains, or build-up, soak in hot water and vinegar. Utensils can be deep cleaned with a baking soda paste (1:2 ratio), or baked at 275°F for 45 min.
