Cleaning Your Menstrual Cup: Complete 2026 Hygiene Guide

Adopting a menstrual cup is a practical, economical, and ecological choice. But to use it with peace of mind throughout your cycles, one question always comes up: how do you clean your menstrual cup properly? From daily rinsing to sterilization between periods and the mistakes to avoid, this guide walks you through maintaining your cup with complete confidence and preserving your intimate comfort.

Why properly cleaning your cup is essential

The menstrual cup is a reusable intimate device, generally made of medical-grade silicone. Unlike disposable products, it remains in contact with the vaginal mucosa for several hours at a time, and then from one cycle to the next. Rigorous maintenance helps preserve the vaginal flora, prevents bacterial growth, and extends the lifespan of your cup (often several years).

Cleaning your cup is also about respecting the silicone itself: certain harsh products can damage it, alter its flexibility, or cause irritation. The good news? Maintenance is simple, quick, and requires very little equipment.

Note: Before handling your menstrual cup (insertion, removal, or cleaning), be sure to wash your hands thoroughly with soap and water. This simple step considerably limits the transfer of bacteria.

Daily cleaning during your period

During your period, the cup should generally be emptied and rinsed every 4 to 8 hours, depending on your flow. At each change, here is the routine to follow:

• Rinse the cup with clear water, preferably lukewarm. Rinsing with cold water last can help limit staining.
• Use a gentle, pH-neutral soap, free of fragrance, essential oils, and harsh antibacterial agents.
• Clean the small air holes at the top of the cup: they are essential for the proper suction effect. A strong jet of water or a soft toothpick is sufficient.
• Dry gently with a clean tissue or let it air dry before reinserting it.

If you are in a public restroom without a sink, a specific menstrual cup wipe (water-based, alcohol-free) can help in a pinch. You can rinse it more thoroughly once you return home.

And for more, to anticipate your changes better, keep an eye on how often you empty it: our guide on full cups and when to empty them will help you find your own rhythm.

Sterilization between cycles

Between each menstrual cycle, before the start of your next period and at the end of the previous one, complete sterilization is essential. It is THE step that ensures impeccable hygiene.

The gold standard: boiling water

This method remains the simplest and most recommended:

1. Fill a clean pot (dedicated, if possible) with water.
2. Bring to a boil.
3. Submerge the menstrual cup and let it boil for 5 to 10 minutes, making sure it does not touch the bottom of the pot (to prevent it from burning).
4. Remove it with clean tongs, let it cool, and store it in its fabric pouch.

According to general hygiene recommendations for intimate devices, boiling for a few minutes is enough to eliminate the vast majority of microorganisms. You can consult the recommendations from the ANSM on intimate products for more information on the subject.

Warning: Never leave the room during sterilization. A pot forgotten on the stove could have all its water evaporate, causing the cup to melt and release smoke. Stay nearby and perhaps set a timer.

Alternative disinfection methods

If you cannot use a pot, several alternatives exist:

• A dedicated electric sterilizer: small devices sold specifically for menstrual cups heat the water and sterilize in a few minutes.
• The microwave: place the cup in a suitable container (glass or compatible plastic), cover with water, and heat for about 3 to 5 minutes at full power. Be careful of the steam when opening.
• Sterilizing tablets: originally designed for baby bottles, they dissolve in cold water and allow for disinfection without heat. Always respect the soaking times indicated by the manufacturer.
• The cup while traveling: opt for tablets or a portable sterilizer, which are more practical than a hotel pot.

Mistakes to absolutely avoid

Some actions, though well-intentioned, can actually damage your cup or unbalance your intimate flora. Here are the main traps to avoid:

• Bleach: too harsh, it damages the silicone and can leave irritating residues.
• Pure white vinegar: too acidic in the long run, it weakens the material.
• Scented or antibacterial soap: these products disrupt the vaginal flora and can cause irritation.
• Essential oils: they can make the silicone porous and create micro-cracks.
• The dishwasher: the detergents used are not designed for intimate contact.
• A toothbrush: the bristles, even soft ones, can create micro-scratches where bacteria will take hold.
• Storage in an airtight container: humidity promotes bacterial growth. Always prefer the provided fabric pouch.

Storing your cup correctly between uses

Between cycles, your menstrual cup must be perfectly dry before storage. Residual moisture is the main factor for bacterial growth and the development of odors.

Store it in its cotton or linen pouch (never in a closed plastic container), away from direct light and heat. A clean, dry dedicated drawer works perfectly.

Finally, inspect your cup regularly: if you notice significant discoloration, micro-cracks, sticky silicone, or a persistent odor despite sterilization, it is probably time to replace it. To learn more about usage precautions, our article dedicated to risks and precautions related to the cup details the points to watch out for.

Note: A typical lifespan varies by manufacturer, but regular inspection and replacement at the slightest doubt remain the golden rule. In case of irritation, itching, or unusual fever during use, remove the cup and consult a healthcare professional.
