Before you sterilise your sippy cup in boiling water, make sure that you thoroughly clean your cup using clean water and mild soap first. Once cleaned, follow the steps below:
- Disassemble the cup
- Bring plenty of water to a boil
- Place all parts in boiling water for 5 minutes
Note: To prevent deformation and damage, make sure that the cup and its parts do not touch each other or the side of the pan.
Note: If you have a Philips Avent insulated straw cup, it is important to not boil or sterilise the bottle with steam or a microwave steriliser. Doing this will damage the product. The cap and straw of the insulated straw cup can be sterilised.
