5-step guide to washing bottles in the dishwasher

Step 1

Pre-rinse the bottles and prepare the dishwasher
Before loading the bottles into the dishwasher, rinse them thoroughly to remove any leftover milk, formula, or other liquids. Make sure that the dishwasher is clean and free of any food debris or leftover detergent.

Step 2

Load the bottles onto the top rack of the dishwasher
Place the bottles, along with their caps, nipples, and rings, onto the top rack of the dishwasher. Make sure that the bottles are securely in place and not touching each other or the dishwasher’s heating element.

Step 3

Add detergent and run the dishwasher
Add a dishwasher detergent that is safe for washing bottles and start the dishwasher on a normal cycle with hot water. If your dishwasher has a sanitize cycle, use it to ensure that the bottles are thoroughly cleaned and sterilized.

Step 4

Remove the bottles and inspect them for cleanliness
After the dishwasher cycle is complete, carefully remove the bottles from the dishwasher and inspect them for any remaining residue or dirt. If necessary, use a bottle brush to remove any leftover residue.

Step 5
