Ensure the lid is properly sealed and screwed on tightly. Check the silicone gasket in the lid for any damage or debris. Clean or replace the gasket if needed.

Drinks are not staying cold/hot for as long as expected.

Ensure the lid is securely closed. Pre-chill or pre-heat the bottle by filling it with ice water or hot water for a few minutes before adding your drink.

Taste of the previous drink lingers.

Thoroughly wash the bottle with warm, soapy water. Use a bottle brush to scrub the inside. For stubborn odors, try a mixture of baking soda and water.
