    You have Questions.
    We have answers.

    • How do I clean my harmony?

      Please use a soft brush or dishcloth to wash the inside and outside— and never put Harmony in a dishwasher.

    • Can I use harmony for carbonated beverages?

      No, do not fill your Harmony with carbonated beverages (such as Coca Cola, Sprite, or similar products) or dry ice, as these could increase the internal pressure, making it difficult to open the lid or creating a risk of spillage.

    • How long can I keep beverages in my harmony?

      Do not store beverages such as juice, milk or tea overnight in Harmony, to avoid bacterial growth and bad odors. And do not fill Harmony with non-food liquids such as essential oils or alcohol, as they could damage the lid and silicone gasket.

    • What is the temperature retention capability of Harmony for both hot and cold beverages?

      Harmony can keep hot beverages above 104ºF and cold beverages below 53.6ºF for six hours when tested at 64.4ºF room temperature.
