Effectively clean your menstrual cup

La Cup Luneale is designed to accompany you safely for many years. For this, regular maintenance is essential.
Here are all our tips to take care of your menstrual cup so that it will accompany you for a long time.

We remind you that before any manipulation, it is important to wash your hands thoroughly. This considerably limits the risk of transmitting bacteria that would be present on your skin, and therefore for example the risk of developing TSS.

1. daily clean of your menstrual cup

During your period, after you empty the menstrual cup, you have to clean it. Some people prefer to simply use water, others with a specific cleanser. It is up to you to find what is best for you.

CASE 1: Rinsing the menstrual cup with water.

Under water, run a finger inside and outside your menstrual cup to remove any residue that may have slipped in. As there is no relief inside the menstrual cup, the blood is eliminated very quickly.

Then check that the holes are empty. Often, there is at least one that is plugged.
In this case, the good reflex to adopt is to fill the cup with water to the brim, place your hand on it and press… In this way, the water pressure opens the holes !

Once that’s done, if you still have your period, you can reinsert it.

CASE 2: CLEANING THE CUP WITH A PRODUCT.

You may be tempted to wash your cup with a mild soap or intimate cleanser.

However, these cleansers are often not suitable in terms of pH and composition, as they can leave residues on the cup, which will then end up in your vagina. This can cause inconveniences (fungus, irritation…) and if their pH is alkaline, it can even influence the development of bacteria responsible for TSS.

We have written a complete comparison of the pH and composition of the main cleaners sold in France that we invite you to read if you want to know more.

If you wish to clean your menstrual cup with a cleansing product, it is therefore important to choose one tested for this use, such as la Mousse Culotte, which has an adapted pH, a natural composition and is Cupfriendly (tested under gynaecological control for use in conjunction with a menstrual cup)

CASE 3: Cleaning your menstrual cup in public places


You are not always at home, and sometimes there is no water nearby or in the toilet.

In these cases, there are several solutions available to you:

Zero waste solution:


You can use a water bottle (with a sports cap, it’s more practical) to rinse your cup in the toilet when there is no sink. It’s very simple, but it’s easy to understand that this can be a bit restrictive.

Luneale Solution:

We created the first cupfriendly intimate wipes that allow you to clean the cup as well as any blood residue on your vulva when you are in a place that does not allow you to clean your menstrual cup with water.
They are packaged in individual sachets, their lotion is natural and they are biodegradable and compostable. This solution, can help you in many cases (at school, at work, on the road, in parties, etc…).

2.Monthly disinfection of the menstrual cup

Beforehand, some information…

The vagina is not a sterile environment. So some will say that disinfection is not mandatory. And they’ll be (partly) right.
Now comes the moment when it’s essential to talk about silicone again.
In this article, we present the different types of medical silicones and discuss the subject of anti-microbial silicones, i.e. they kill bacteria, viruses, fungi and parasites (=what are commonly called microbes). They are used to make some medical catheters, medical device keyboards, dressings… and some menstrual cups.

Why did Luneale choose not to use antimicrobial silicone for La Cup?
The vaginal flora is composed of good bacteria, essential to the intimate balance: they protect the vagina. However, since the scientific literature is rather weak (or even non-existent) on the actions of silver ions on the vaginal flora in the medium and long term, and since silver ions eliminate bacteria, we believe that it is not desirable to use antimicrobial silicone to make a menstrual cup.

On the other hand, the platinium grade medical silicone used for La Cup Luneale is naturally bacteriostatic, meaning that bacteria do not grow on its surface.  This is the reason why a monthly disinfection of La Cup Luneale is recommended, because if the bacteria do not develop there, those present on its surface remain there for the time of their “life” in the open air.

Now let’s get right to the point. How do you sterilize a menstrual cup?

If purists talk about disinfection (sterilization is a very technical process), boiling a menstrual cup will remove most of the germs on its surface and allow it to regain its appearance of the first days.
Disinfection is generally done once a month (between periods): we advise to sterilize it just before menstruation, so that it is disinfected during insertion. But if you want to do it also after your period to put it away, it is possible.
Caution: pour boiling water over the cup in a bowl and wait 5 minutes is not effective. The cup must be in boiling water.

2 methods are possible, with equivalent efficiency :

CHOICE 1: Sterilization in a pan.

Boil a pot of water and dip your menstrual cup in it for 5 minutes, taking care not to leave it too deep in the bottom so as not to risk burning it. For your information, the silicone of La Cup Luneale resists to 240°C.

Our tip: To make sure it stays suspended and does not touch the bottom, you can place your cup in a kitchen whisk.

CHOIX 2: Microwave sterilization.

La Cup Luneale’s silicone is certified to resist much more aggressive waves than those emitted by a microwave, so there is no risk in using this technique.

However, there is one important recommendation:
We do not recommend using a plastic container to sterilize your cup in the microwave, because plastic can release micro-particles under the effect of heat, even if they are said to be microwaveable. The ideal container to sterilize your menstrual cup in the microwave is a glass container.

Here are our daily tips and recommendations, we hope we have enlightened you. If you have any questions or other tips to share, please feel free to leave a comment!
