How long to boil a menstrual cup (and how to do it safely)

Lunette Cup Wash used to clean a menstrual cup

Boil a Lunette menstrual cup for 5 minutes. Do it before you use the cup for the first time and after each completed cycle. Make sure the cup doesn't touch the bottom of the pot. During your period, you don't need to boil it: rinse or wash it with warm water each time you empty it.

How to boil your menstrual cup, step by step

  1. Wash your hands and rinse the cup.
  2. Use a pot with plenty of water, enough that the cup floats freely.
  3. Bring the water to the boil, then put the cup in.
  4. Keep it off the bottom of the pot. A cup resting on the hot base can be damaged.
  5. Boil for 5 minutes, then take it out with clean tongs.
