How to Clean Your Menstrual Cup

Posted by Gee Ann on

Since menstrual cups are reusable, it's important to clean and care for them properly so they will last! We share how to clean your cup during and in between periods, along with wonderful tips that our customers have shared with us.

Clean Hands

Wash your hands with water and a mild soap before you handle your menstrual cup. Your hands may have touched many bacteria-laden things before you handle your cup, such as door handles, computer keyboards, elevator buttons, etc. Anytime you're going to touch your cup (or yourself), remember to wash your hands. This will reduce the risk of infections, and keep the vagina and surrounding area clean.

Before First Use

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. In a large pot, submerge the cup in water and boil for 10 to 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.

Cleaning on Your Period

During your period, it is best to wash your cup with mild soap and water every time you empty it. We recommend using the Lunette FeelBetter Cleanser, a mild cleanser that's specially formulated for washing a silicone menstrual cup. If not, you can also use other liquid soaps that are oil-free and fragrance-free.

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 Lunette Cupwipe, which disinfects the cup. You can also just use clean tissue or toilet paper in a pinch – once convenient, wash your cup thoroughly.

Cleaning The Airholes

Fill your cup with water, place your palm on it, turn upside down and squeeze. When the water squirts out through the airholes, they are instantly cleaned! You can also use a blunt toothpick, or an old toothbrush that's dedicated for this purpose. Do not use sharp items like needles, as you may accidentally damage your cup.

Between Periods

At the end of your period, it is best to sterilize it before storing for the next use. You can rinse your cup, submerge in water and boil for a few minutes. You can also put your cup into a mug filled with boiling hot water (from the kettle) and let it sit covered for a few minutes.

You can also use the Lunette FeelBetter Cleanser to thoroughly wash your cup before letting it dry and storing it. Other suggestions include using a steam sterilizer for baby bottles, or sterilizing tablets.

Getting Rid of Odour

If your cup has an odour even after washing it, you can set it in a place with direct sunlight (e.g. near a sunny window) for a day. This should get rid of any lingering odour on the cup.


Never store your cup in a plastic bag or an airtight container. It's best to store it in a breathable cotton bag. Most cups come with their own little bag included. You can also just leave it out in the open, in your bathroom or somewhere with good air flow.

Good hygiene and cleaning practices will make sure your vagina stays healthy, and your cup remains in good condition. If your menstrual cup starts to deteriorate and show wear and tear, such as a sticky or powdery film, splitting of the cup, or severe discolouration and odour, it's time to replace your cup.
