Hygiene is very important to a growing baby. It is good to wash your pacifiers or teethers after each use. To wash pacifiers and teethers, we recommend using PIGEON Liquid Cleansers. Follow cleaning instructions on the liquid cleanser packaging and rinse thoroughly after each wash. You can also sterilize both items if necessary, and wipe with a clean towel dipped in warm water or with our Anti-bacterial wet tissue. Always remove trapped water before use.
