Yes. To prevent mold and bacterial growth, it's a good idea to wash your diaper pail at least once a week using warm, soapy water or an antibacterial cleaning solution. After rinsing, wipe the pail down with a dry cloth and allow it to air dry for a few hours before replacing the liner and closing it up.For stubborn odors, try using a vinegar/water rinse, or place a small tray of baking soda in the bottom of the pail to help absorb lingering odors.There is one caveat to this answer, and that applies to steel diaper pails. Steel diaper pails should not be washed, as this could cause them to rust. If you use a steel diaper pail, keep it as dry as possible, and always follow manufacturer cleaning instructions.
