Infant formula needs to stay dry, so don’t clean scoops unless they’ve dropped on the floor or become soiled. Then wash them as you would a baby bottle and allow the scoops to air dry before you return them to the container.
Never clean the inside of an infant formula container as it’s less likely to become contaminated if it stays dry. Babies get sick from contamination on the outside of the infant formula container.
If you need to clean the outside of the container, use a disinfectant wipe or paper towel sprayed with disinfectant to wipe it down. Wait until it’s dry before opening it.
