Inspect your menstrual cup before each use for signs of deterioration, such as a sticky or powdery film, severe discoloration or odor, or if you experience irritation or discomfort, you may want or need to replace it or give it a thorough cleaning by boiling it and washing it well.
You need to sterilise your cup only once per cycle, at the end or at the beginning. While you are having your period you can simply rinse your cup with water and mild soap if available. You do not need to sterilize your cup it every time you reinsert it, only between cycles. The medical grade silicone the cup is made of has natural antibacterial properties so as long as your hands are clean it is perfectly safe.
At the end of your period, wash your menstrual cup thoroughly and store it in its own carry bag, pouch or box provided with your cup. Do not store it in a airtight container or plastic bag as moisture cannot evaporate without airflow and your cup will not dry properly.
The way you sterilise your cup depends on the method you feel more comfortable with. You can sterilise your cup by boiling it in an open pot of water for 3 to 5 minutes or by using Milton sterilising tablets, commonly used for babies feeding utensils. Dip your cup in water with a tablet for 15 minutes and you are done. You can also rinse it in a solution of 10% vinegar and water, but do not rinse it for more than 3 minutes; you could damage your menstrual cup.
Ensure that the tiny suction holes at the top of your cup are clear as they help form and release the seal. To clear the suction holes of menstrual fluid, we suggest that you gently stretch each hole under warm running water to remove any debris. You can also fill the cup with water, cover the opening with your palm and squeeze the cup to pressure water out the holes or carefully use a toothpick.
Over time, you might notice some discolouration of your cup. This is normal, a discolored cup is still clean and safe. If you notice any rips, tears or changes in the texture of your cup, you should dispose and replace it. If your cup develops an odor, based on the cleanser you used and a number of factors unique to each woman, the silicone may be compromised and you should dispose of your cup and buy a new one. To dispose of your cup, thoroughly wash the cup, cut it up into smaller pieces and throw them in the trash.
When cleaning your cup avoid using products such as tea tree oil, scented or fragranced soap, castile or peppermint soap or any other oil based soap, rubbing alcohol, antibacterial soap, hand sanitizer, hydrogen peroxide, dishwashing soap, bleach or harsh chemicals of any kind that could compromise the quality of the silicone by leaving a sticky or powdery film on it that could create discomfort, irritations, burning, itching etc.
The ingredients in lubricants can damage the silicone, so we suggest to only using water based lubricants to help in the insertion of the cup.
Do not clean the cup in a dishwasher because chemicals, detergents and residue from previous dish washing could harm the cup.
