If time isn't on your side, you may wonder if you can rinse out a baby bottle. Unfortunately, germs can grow fairly quickly from a dirty bottle, and rinsing them out won't get them thoroughly clean. The Centers for Disease Control and Prevention (CDC) recommends cleaning baby bottles with hot soapy water or running them through the dishwasher after each use.  Make a point to separate each part of the bottle to ensure a thorough cleaning. It's extra important to sanitize bottles daily if your child is under 3 months, if they were premature, or have any other health condition. If your baby doesn't check one of those boxes, you can limit sanitizing to once a week.  RELATED: The Best Bottle Sanitizers of 2022
