According to Menstrual cup makers, Mooncup recommends removing and cleaning the cup every 8 hours. They said “A light seal is formed with your vaginal walls, allowing menstrual fluid to pass into the Mooncup without leakage or odour. This seal is released for removal, allowing you to empty the contents, rinse or wipe and reinsert. Comfortable, convenient and safe: the Mooncup can be used overnight and when travelling, swimming or exercising.”
Some users of the tool added that observing strict hygiene rules before and after inserting the cup is essential.
