How To Clean Your Lunette Cup

For us gals who use Lunette cups, keeping it clean is the most important thing. After all, the cup is going into our bodies. Although some believe that reusable does not equal clean (they´re wrong), we should all remember that even disposable products are not completely sterile. With proper care and a quick clean, your Lunette cup will be ready to serve you for another reuse.

First use: Wash your hands and clean the Lunette cup by washing with water and a mild liquid soap free of coloring agents and parfumes. Then boil it in a large amount of water for 20 minutes before first use. Make sure that there is enough water so that the cup does not burn on the bottom.
TIP: Place the cup in a wire whisk to prevent contact with the bottom of the pan during boiling.

For day-to-day cleaning: We of course recommend our Feelbetter Liquid Wash that is designed for washing a silicone cup. But you can also use some other liquid soap that is fragrance-free, oil-free and has a mild to acidic pH (between 3,5 and 5,5). Just be sure it does not contain oils, since they can stick to the cup and create a film that could irritate the body. Do NOT use washing up liquid or wash your cup in the dishwasher! THAT is a definite no no!

To disinfect the cup after your cycle so it is ready for the next time: with our Cupwipes, or wipe down with rubbing alcohol (alcohol denat.). Lunette can be boiled for a few minutes in a clean pan and some gals I know use those microwave containers for sterilizing baby nappies. Just remember to keep the cup submerged in water so that it doesn´t burn or get cooked. This happens all the time! That’s why I think using alcohol is the best option. It is easier & quicker – not to mention accident-free.

Lemon juice is an organic way to clean your menstrual cup!To get rid of lingering odor: Set in sunshine for a day. The odor thing happens for some people, our scent and sense of smell is different. Mine has never had an odor but we get this question from time to time. Also, lemon juice: Just squeeze a lemon and wipe the cup with or soak in. Works!

***The best way to get rid of stains*** is to soak in 3% Hydrogen peroxide. The kind you get at the grocery store in USA. After a soak, it will make the cup look like brand new. Or so I hear. This tip is from an American colleague, haven´t tested myself. If you want a more natural alternative, try spirit vinegar. And lemon juice works for stains too.

Cleaning the airholes: fill the 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! Also you can use a blunt toothpick soaked in rubbing alcohol. Or a toothbrush dedicated to this purpose. Do not use sharp items on your cup, like needles and such. They will do more damage than good.

Saving the best for last: Always wash your hands! Hands can be full of germs that can travel from your cup to your vagina. So hand hygiene is vital. If nothing else, remember that!

    Thanks for the whisk idea for boiling! It certainly beats sitting there the whole time batting it with a wooden spoon!

    I’ve done the 3% hydrogen peroxide soak on a previous cup (not a Lunette, but still silicone), and it did work really well. If you soak for 24 hours, it will disinfect, too. (Granted, the other methods are still quicker.) I’ve also hear of people using cheap, plain vodka for disinfecting in place of the rubbing alcohol.

    hey girls, is not good to use oil base products cos can form a sticky layer around the cup and grow bacterias and difficult to clean.
    Lemon works great to clear and clean things, but is also oily! squeeze a lemon and feel your hands… is naturally oily.
    are you sure you can lemon on the cup? Im not sure…

      Hi Janis! You know, it works for a few reasons. Although lemons contain oil, remember it takes a whole lot of lemons to extract a usable amount of oil. Also, it a natural de-greaser, what little oil is in one lemon doesn’t create a coating. Finally, lemon juice has natural antibacterial and antiseptic qualities that make it a powerful, yet natural cleanser.

    Thank you for suggesting alcohol. I live in a place where the kitchen is the hub of the house, and it would be pretty inconvenient and embarrassing to boil my menstrual cup.
    For the first time use though, you definitely recommend boiling it?

  • Tracey

    Thanks for these tips. I’ve had mine soaking in Hydrogen Peroxide for a few hours and it seems to be working quite well. My question is how long do I soak it and how often should I do this? It seems like it could wear down the material if I did it too frequently?

    • Cathy

      SO glad that the tips helped! Thanks for letting us know!

      Tracey- You can soak your cup in H.P. for up to 12 hours…as needed. As long as your keeping your cup clean after use you shouldn’t have to do that very often.

    Hello! i recently purchased a lunette and i was wondering the same thing as G.Lee17. Please answer her or my question. I also live in a place where there is no privacy at the kitchen and would be really awkward and uncomfortable to boil my cup. Is it really that necessary to boil it before first use?

    • Lilli

      Hi Daniela! It is recommended to boil the cup before first use to sterizile it. Remember, it’s just a clean piece of silicone at that point, so it’s not so embarrassing, really!

      You may also use Lunette CupWipes or rubbing alcohol instead of boiling.

      You may also use the microwave to boil water, say, in a mug or other microwave-safe container. Microwave ovens vary, but on average, it will take 1 minute on full power to get water to boil, and after that, keep the cup boiling for the recommended 20 minutes. Make sure there’s enough water to keep the cup submerged in the boiling water at all times and that it keeps boiling.

      Then remember to wait for the container to cool before taking it out!
