A sippy cup is exposed to various germs and bacteria with each use. Keeping your child's cup sanitary is vital to protecting her from germs that cause viruses and disease.

Rinse the cup in cold water to remove any liquids or residue.

Dissolve the dish soap in a sink of hot water per the detergent's directions. Remove the cup's top and submerge both pieces in the soapy water.

Use the dish towel or sponge to thoroughly wash the cup. Wash the interior and exterior of the cup and lid. Wash every crevice and completely rid the bottle of any odor or residue.

Fill the pot with water. Submerge the cup and lid in the water. Place the pot on a stove burner set on medium-high heat. Allow the water to come to a boil.
