Boiling, Steam, or Chemical Sterilisation: We recommend replacing the bottle every 6-12 months. If you notice stubborn milk stains, scratches, or discoloration on the bottle, it’s time to consider getting new ones. For silicone teats, we recommend rotating between 2 or more teats every 2 months before replacement if subjected to boiling, steam, or chemical sterilisation.
UV Sterilisation: When using a UV steriliser with a drying function, ensure the bottle is at least 1 inch (2.54cm) away from the inner wall and ceiling with the air ventilation outlet. This may avoid any damage or deterioration of the bottle. UV sterilisation may lead to premature aging, especially with repeated use. Therefore, we recommend you to replace the product if it starts to discolor or become cloudy.
