<bot>: The safest and most effective way to clean a baby's bottles is to use hot water and a mild, liquid dish soap to wash the bottle and its components. After washing, rinse the bottle with hot water to remove any residue. Then, disinfect the bottle by either boiling it for at least five minutes or by using a solution of one teaspoon of unscented chlorine bleach in a gallon of water. Lastly, rinse the bottle again with hot water and allow it to air dry.
