Before using the cup for the first time, check that the air holes at the top are open. Wash your hands and clean the cup by washing with water and a mild soap. Then boil it in a large pot for 20 minutes before first use. You may place the cup in a wire whisk to prevent contact with the bottom of the pan during boiling, which may damage it.
During your period, it is best to wash your cup with a cup cleanser and warm water every time you empty it. However, if you are using a public restroom, camping, travelling or just do not have access to running water you can either rinse your cup with bottled water or wipe it with a piece of clean tissue – once convenient, wash your cup thoroughly.After your period has ended, clean the cup thoroughly with a cup cleanser and warm water. You may also sterilise your cup with a menstrual cup steriliser or baby bottle steriliser. You may let the cup sit near a sunny window to remove discolouration and odour. Store the cup in the cotton pouch or any breathable container or bag.You can refer to this blog post for a thorough guide on cleaning and caring for your menstrual cup!
