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.

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***

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!

You guys suggest cleaning it with rubbing alcohol but isn't that bad for your vagina?

Lunette team 23 06 2015

Hi Kelsey!
You shouldn't put the cup back in when it's still wet. Let the rubbing alcohol dry and then use the cup. That way it won't hurt your vagina.

Is dr. bronner baby unscented pure castile liquid soap a good soap to clean the lunette with?

Chardon 02 07 2015

Is Dr. Bronner's Uncented baby-mild pure castile soap good to use to clean the lunette?

Cassie 14 07 2015

Can I use Dove Sensitive soap to clean my cup with?

Lunette team 14 07 2015

Hey all!
We recommend using Lunette Feelbetter wash with Lunette cups and with other soaps we can't unfortunately say anything for sure. We don't know the ingredients of all brands so please just check that the soap is mild, fragrance-free and doesn't contain oils. If you notice any burning or itching feeling stop using the soap and clean your cup with rubbing alcohol properly.

Kristina 07 08 2015

I have a lunette and a diva cup. Is it okay that I use the diva wash for both cups?

Lunette team 07 08 2015

Hi Kristina!
Unfortunately we don't know exact ingredients of Divawash but since it's made for silicone menstrual cup it should be totally safe to use with Lunette cups too.

Luciana 15 09 2015

Hi, there. Is it OK to use those microwave sterilizer bags to sterilize my Lunette? I was just wondering, cause we use only 60ml of water and the cup is not under water...

Lunette Team 17 09 2015

Hi Luciana, in theory I would say that Lunette can be sterilized with that kind of bag which is intended for silicone pacifiers and teats. The bag creates steam that sanitizes, right? But these sterilizing bags have not been tested with our cups so I cannot say for sure. Usually we recommend that the cup is fully submerged in water when boiled in a microwave.

Donna 23 09 2015

Hi I'm wondering can I wash my cup in Milton after my cycle or do I need to boil it again?? Or is it as simple as using the Lynette feel better wash letting it dry and putting it in the bag until next month? Sorry this is all new to me and I want to make sure that I'm cleaning my cup correctly :) Thanks Donna

Donna 24 09 2015

Hi, I'm wondering if I can clean my cup with Milton at the end of my cycle? Or do I just use the feelbetter wash and pop it bag in the bag for next month? Sorry I'm new to this and I want to make sure that I'm cleaning my cup correctly. Thanks Donna :)

Lunette Team 24 09 2015

Hi Donna! Feel free to ask as much as you want! We recomment to clean it with our cleanser because it is the most optimal for Lunette cup. You can wash your cup with it during the period and then at the end of the cycle and then store the cup in its bag. Next month just wash it again before first use and you are good to go :) You can boil it too if you want but it is not necessary. If you want to boil it just make sure the water boils for 20 minutes to kill all the bacteria. Our cup wipes sterilizes 100% and are super easy to use. Just make sure the cup is dry when you put it back in.

The reason we always recomment our own cleaning products is that we have tested it with our cups and are one hundred procent sure they don't harm you or your cup.

Hope this helped you!


Linda 29 12 2015

Hi, I was wondering if it's okay to sanitize my cup, at the end of my cycle, in Milton sterilizing tablets, which are used to sanitize baby's pacifiers. Also, can I use feminine wash to clean it? I've read somewhere before that it's okay if it's feminine wash since it's designed to use on the genitals, but I just wanted to check to make sure.


Lunette Team 29 12 2015

Hi Linda!

We cannot promise 100% that Milton tablets sterilize the cup perfectly. They don't seem to do a huge harm, but unfortunately we can't promise anything sure because we haven't tested them :/

It depends on a lot what kind of a feminine wash you are using. If it contains oils it is super bad for the cup. The best wash for Lunette cup is a Lunette cup cleanser. It is super plentiful so you can use one bottle even for few years!


Kathryn 31 12 2015

Hi! I was wondering if it's okay to just rinse my cup with water every time I take it out and then reinsert it, and then boil it at the end of each cycle to sterilize it? Is that hygienic enough or do I NEED to use a mild soap to clean it as well? Have a happy new year!

kyra 02 01 2016

Hi there iv just recently bought this cup and i was just wondering instead of boiling my cup for 20minutes in a pan before use and to sterilise it after use i was wondering if i would be able to just submerge it in boiled water straight from the kettle in a air tight container for the 20 minutes instead?
Thanks Kyra

Lunette Team 04 01 2016

Hi Kathryn!

It's fine just rinse it if you put it straightaway back in. Just make sure you sterilize it properly afterwards :)


Team Lunette 04 01 2016

Hi Kyra!

Unfortunately we cannot promise that will work the same way.


marisa 29 01 2016

I'm interested to know if women generally use a pot specifically for boiling their cup in that is not used for cooking food? would that be unhygienic?

Lunette Team 03 02 2016

Hi Marisa!

Some like to have their own pot just for boiling the cup, but it is 100% safe to use the same pot that you cook with. Just remember to clean it properly :)

Gabi 10 02 2016

Hi! I-ve just got my lunette! But I'm in the outback now so I have no access to any good store like the one I got my cup from or even a good pharmacy. So I can't get any soap which is not the common soaps with fragrance on them. Reading the comments you said its ok to wash the cup with a rinse with water as long as you put it back. Here I have rain water (which is the one I drink) or water with lots of minerals, which I use for washing. Which one should I use?

In the case I don't use the cup straight away but the next day, is it ok to use the alcohol? should I use a sterile gauze to put the alcohol on and then rub it to the cup? Afterwards do I put it back in the little container? Should I do the same (with alcohol? or boiling water?) before using it again the next day?

Should I wash the little container the first time after I sanitize the cup?

Thanks a lot!

Lunette Team 16 02 2016

Hi Gabi!

Just rinsing the cup is okey but if there is a big time gap between that and the next use, I'd recommend boiling the cup before the next use. And use the rainwater if possible.

Alcohol is fine as long as it is pure alcohol. For example wound sanitizing liquid is good but disinfectant for hands is absolutely no-go. With alcohol, it is enough just to rub it carefully, you don't deep to soak the cup in it. Our Lunette cupwipes is a good example of a handy use of alcohol :)

All in all you are totally good to go just with clean water and decent access to boiling conditions! :)


Jenny 22 02 2016

Hi, Ive recently bought a Lunette cup and I'm absolutely in love with it. But my problem is that I didnt read the direction for first time using, so I didnt know that we have to boil it for 20mins first time using it. I just boiled it for about 5mins because I was scare that I burn it :( and now that I know abt that, I'm very concern that it may cause harm to my body

Lunette Team 23 02 2016

Hi Jenny!

If you didn't get any rash or it didn't cause itchiness, you're fine :) The most important thing is to disinfect the cup by boiling for 10 minutes or using our cup wipes (they are made of alcohol and water) before the every first use of the period. During the period you don't need to disinfect it every time you empty it.


Kara 16 04 2016

Hi - I was wondering if steaming the cup in a bamboo steamer for 10minutes is a good way to clean and disinfect it?

Lunette Team 18 04 2016

Hi Kara!

It is a very good way! :)


Irene 21 04 2016

Hi, I don't like to use the cup overnight and I was wondering if I need to sterilize the cup again before I use it again next morning or if it is ok to just wash it well? Thank you.

Lunette Team 22 04 2016

Hi Irene!

It's ok just wash it well :)


Tania 03 07 2016

Greetings! I am about to use the cup for the first time and trying to find a good soap to give it a first wash. Looked into the one you recommend here, Feelbetter Cup Cleanser and noticed it has this in its description: "Scented with lemon and eucalyptus oil for their purifying properties." Didn't you mention earlier that the cup should be washed with oil-free soap?


Lunette Team 05 07 2016

Hi Tania!

There is a very small amount of essential oils in the Feelbetter Cup Cleanser and they won't harm the cup :)


Emily 31 07 2016

Hey there! I have a cup that I used once for my last period. I did everything correctly, from the boiling to the washing. I stored the cup in the little bag it came with. Now my period should be coming on and I went to check my cup and there was a white, almost dust-like film on the cup. Is this normal and is the cup still safe to use?

Lunette Team 01 08 2016

Hi Emily!

The dust comes from the water. Wash the cup with Lunette Feelbetter cupwash and you're good to go! :)

Jane 11 08 2016

I'm hoping to use the wipes to disinfect my cup in between cycles, but I can't clean the air holes with the wipes. Is it enough to wipe around it or should I boil the cup? Thank you!

Lunette Team 11 08 2016

Hi Jane!

Roll the corner of the wipe between your forefinger and thumb to get a tight and small "stick" out of it. Stick one corner through one hole, there are conveniently four corners in the wipe and four holes in the cup :)


Esme 26 08 2016

Hi, I just got my cup and it says to boil for 20 mins. After I finished boiling the cup seemed to have a powder like white film. What do I do about this and how do I avoid it next time?
Thank you,

Lunette Team 26 08 2016

Hi Esme!

The powder comes from the water. Just wash the cup with Lunette cup wash and or other proper wash for the cup and you're good to go! :)


JjAZMIJazm 21 11 2016

Hi there,

Do you HAVE to boil the mooncup before the first use?

As I live with 4 boys and can imagine it being pretty awkward...

Thank you.

Lunette Team 21 11 2016

Hi JjAZMIJazm!

You can disinfect the cup with Lunette cup wipes as well! They contain only water and alcohol and kills all the bacteria :)


Shar 25 11 2016

Hi! I've looked but I don't see how to use the Lunette FeelBetter Cup Cleanser. Do I use a drop in a water solution or do I apply it straight onto the cup?

Thank you :>

- Shar

Lunette Team 29 11 2016

Hi there Shar!

Just apply a drop of the cleanser onto the cup, rub a bit and rinse well! :)


Mel 14 12 2016

Hello! I´m using a soap to clean my cup, but I´m not sure if it´s the right one. I don´t want to damage the cup or my vagina.

The ingredients of the soap are: Water, Sucrose, Sodium Oleate, Sodium Laurate, Sodium Stearate, Sodium Palmitate, Sodium Myristate, Glycerin, Sodium Caprylate, Alcohol, Sodium Caprate, Linalyl Acetate, Yellow 10 (CI 47005).

Has no perfume and it´s hypoallergenic. I didn´t find any information about the PH of the soap in the package and I contacted the brand but they would´t give me that information...

If I can´t find the right soap is it best to wash it with just water?


Lunette Team 15 12 2016

Hello Mel!

The soap doesn't sound extremely bad. The glycerin can leave residues on the cup and that might irritate your vagina. If don't notice any changes on your cup or irritation, feel free to continue using it :)


Mel 15 12 2016

Perfect! Thank you!

Rhiannon 17 01 2017

I was preparing my cup for first use and I accidentally missed the soaping step but I have boiled it for the stated amount of time. Is this ok, or is it crucial to use soap then boil before first use? Also I noticed some residue around the pan I used is this usual?

Lunette Team 18 01 2017

Hi Rhiannon!

The purpose of washing the cup with soap at first is to get rid of the dust potentially left on the cup. The boiling is the most important part so forgetting the washing part isn't so dangerous. The residue is most likely a calcium from tap water. Just wash it away and you're good to go! :)


Maddie 19 01 2017

I just received my first lunette cup and did the initial 20 min boil. I made sure the cup didn't touch the bottom of the pan, but the string tip turned slightly brown. What did I do wrong? Is the cup still safe to use?

Madison 23 02 2017

I just bought my first cup, and after having it in boiling water for 5-10 min, it came out with a yellowish tinge on the whole cup. It was originally the 'clear' colour. This boil was the initial one, and I haven't used the cup yet. Is this unusual and should I be concerned?

Lunette Team 23 02 2017

Hi Maddie & Madison!

There is a chance that the cup burned a bit. Try to rub with Lunette Cupwipes or rubbing alcohol. If the stains remove and there aren't any other visible changes on the cup, you can start to use it! :)


First timer 13 03 2017


I work long hours in various locations. On forums, many people say it's ok to just empty the cup and reinsert it immediately (when you're in a public toilet cubicle and don't want to rinse it out in the public sink). Is this OK? If so, what's the max duration one can do this before you need to rinse the cup out (some say 12 hours)?

Others say they use toilet paper, but this sounds unsanitary. Can I use alcohol wipes instead when I'm on the go?


Lunette Team 14 03 2017

Hi there First timer!

It is not the end of the world if you don't rinse and wash the cup every time you empty it. Just make sure to take good care of hand hygiene! The cup should be emptied and washed every 12 hours. And you can totally use the cupwipes when you're on the go!
