How do I clean the valve?
Firstly, unscrew the lid, taking the valve out. You may need to do this by wiggling the valve from left to right.
Separate the white retainer from the clear silicone, washing all parts thoroughly in warm soapy water, then rinsing in clean water (or use a dishwasher on the top shelf only) after each use. Additionally, our valves are suitable for sterilization by steam (electric and microwave) or boiling (5 minutes) after the washing process.
We suggest allowing the valve to dry prior to reassembling if storing the cup away.
To re-assemble, connect the clear silicone and white retainer parts together, placing back into the lid, pushing until the sides lock into place.
