Menstrual cup stains are super common and are a badge of honor in a way… It shows a lot of use, how you’ve dedicated your cycle to less waste (think of all the products you’ve kept out of landfills!), and that you’re making healthy decisions for your body. Still, they can be an eyesore. So if you love your cup and want to keep it looking like new, don’t worry — it’s possible to remove menstrual cup stains and prevent them in the future!
How do I clean off any staining?
If your cup is dingy or has staining, scrubbing it alone probably won’t be enough to get it looking fresh again. You’ll need to use a product specifically for stain removal. Fortunately, there are several stain-removing solutions that are safe to use, environmentally friendly, and easy on the wallet.
Hydrogen peroxide is an effective stain remover for protein-based stains, which includes period blood. Hydrogen peroxide is simply water with an extra oxygen molecule attached. That extra oxygen molecule is what gives it its stain-fighting power. The 3% solution sold as a first-aid antiseptic can also be used to remove period stains from your cup, as well as from other materials such as cloth pads, sheets, and underwear (but test it on colored fabrics to make sure the colors won’t fade).
To clean your menstrual cup with H2O2, soak it at room temperature for an hour in a glass container or jar with 1/3 cup hydrogen peroxide and 2/3 cup water. This should eat the stains away on its own, but if there is anything remaining, take a toothbrush or washcloth and give your cup a good scrub.
Sodium percarbonate, also known as sodium carbonate peroxide, is a salt that also contains active oxygen, which makes it excellent for stain removal and cleaning. Sodium percarbonate can be considered an alternative form of hydrogen peroxide; when added to water, it releases hydrogen peroxide. The Environmental Working Group gives sodium percarbonate a safety score of 1-2, meaning it has the lowest possible health hazard when used as directed.
We developed our new Pixie Cup Dust stain remover with sodium percarbonate for both its effectiveness and convenience. It’s a powder, so it’s easy to use, takes up hardly any space in your bathroom, and has a long shelf life. It also contains sodium carbonate, another gentle cleaning agent made up of sodium and acid. Sodium carbonate also has an EWG rating of 1, making Pixie Cup Dust safe for you, safe for your septic system, and safe for the environment.

How do I prevent menstrual cup stains?
Sterilize your cup regularly. The best way to keep your cup stain-free is to do your best to prevent staining! In addition to washing your cup each day and sterilizing your menstrual cup before and after each period, make sure you are giving your cup a scrub in the areas that often experience buildup such as around the rim and in the grooves of the stem. Also, try to minimize the amount of time the cup is exposed to the air without a thorough cleaning because this can lead to the darkening of the silicone.
Give it a good scrub. You may think your cup is beyond saving, but we want to assure you most stains can come off! Are you ready for one of our best stain-removal hacks? Here we go: grab an old toothbrush and scrub your cup with a little warm water and some silicone-safe cleaning solution! You will be surprised how much of the “staining” comes off with this technique!
Let it soak. We all need a steamy bath sometimes, even your menstrual cup! Squirt a little of the cleaning solution mentioned in Step 2 into a bowl or your Pixie Cup Cup with some hot water and let it soak for a few hours! Pair this with a good scrub and you can say goodbye to some tough stains!
Sunsoaking your cup. Placing your menstrual cup in a sunny location (preferably outside) for a few hours will do a world of good for any discoloration. Sun bleaching has been around for centuries and has never let anyone down yet.
Grab some Pixie Cup Wash and an old toothbrush and go to town scrubbing! Your cup will be sparkling in no time.
Have you noticed an odor coming from your menstrual cup? The truth is, if you use your cup at all, there’s a risk that you could end up with a stinky menstrual cup on your hands. While a menstrual cup smell doesn’t necessarily mean there’s anything wrong with your cup (or with your period), it can be annoying. The good news is, there are some steps you can take to make sure that your cup stays sparkling clean and smelling nice even after years of use, and it’s really not that hard to do!
Is it normal for my menstrual cup to smell?
Yes! It’s completely normal for a menstrual cup to develop an odor with regular use. This odor may be completely different from the smell associated with your menstrual flow. Some people have described the smell as similar to eggs, broccoli, or sulfur. Others have described the menstrual cup smell as sour. But don’t worry — it’s unlikely that other people will notice the smell of your menstrual cup or the smell of your period. But if it bothers you, here’s how to fix it!
How do I get the smell out of my menstrual cup?
The tips below will help remove both smell and discoloration from your menstrual cup. It’s always a good idea to read your manufacturer’s instructions for your specific cup brand. The following is what we recommend for Pixie Cup menstrual cups. If you have a cup from a different manufacturer (such as a Diva Cup or a Lena Cup), they may recommend different cleaning and sanitizing procedures.
Prevent or remove menstrual cup smell with deep cleaning
If you’ve noticed that your menstrual cup has a weird smell, or if you just want to prevent it from smelling in the future, make sure to keep your cup sparkling clean. It’s really important to take good care of your cup and keep it clean at all times, and this will help decrease the likelihood of any unpleasant odors.
We recommend deep cleaning and sanitizing your cup before and after each period, and giving your cup a quick rinse when you change it at least once a day. This will dramatically reduce the likelihood of unwelcome smells.
Menstrual cups are safe to wear for up to 12 hours. Ideally, it’s best to remove and empty your cup even more frequently — every 4 to 8 hours if possible. Leaving your cup in for longer than recommended can increase the chance of an odor developing. If your cup already has an odor, leaving it in too long could make it worse.
Rinse with cold water first
You may be tempted to wash your cup in hot water right after you take it out, but hot water can actually cause odor and stains to set in. When you remove your cup, wash or rinse it in cold water first. You can follow this by washing it in warmer water. The same is true for underwear or other clothing that gets menstrual blood on it: Give it a good scrub in cold water to keep stains from setting.
Give it a good scrub
Set aside a toothbrush that is designated just for your cup. After rinsing your cup under cold water, give your cup a good scrub with soap. We recommend our Pixie Cup Wash. Avoid using soap or other cleaning products that aren’t intended specifically for menstrual cups — they may contain oils, fragrances, or other chemicals that can increase the risk of odor or harm the silicone. When you wash your cup, make sure you get in between the grooves and clean the air holes around the rim to remove any residue that can build up in those areas.
If you’re changing your cup in a public restroom and can’t wash it, it’s fine to just wipe it off and reinsert. Keep some menstrual cup wipes in your bag or pocket for this purpose, and just make sure to give your cup a good wash the next time you’re at home.
Steam or boil your cup before and after your period
Before and after each period, we recommend sanitizing your menstrual cup by steaming or boiling it. You can boil it on the stove for 2-10 minutes. Or, to make sanitizing your menstrual cup easier, we created our menstrual cup steamer. The steamer sits right on your bathroom counter and sterilizes your cup in just three minutes!
Give your cup a sun bath
Find a nice sunny spot and let your cup soak up some rays for a few hours! This will help with both odors and discoloration. Just don’t leave it where it may get too hot or melt.
Use a naturally scented rinse every month or two.
Sometimes your cup needs a little more than soap and water to keep it smelling fresh. You can create an all-natural menstrual cup rinse with just some lemons and vinegar! Make sure to boil or steam your cup before use to remove any lemon or vinegar residue.
One last note…
Keep in mind that vaginal infections and yeast infections can cause unpleasant smells. If you notice an unpleasant or unusual odor that isn’t just related to your cup, it may be time to see your doctor.

Which is better, steaming or boiling your menstrual cup? Does it matter? It really comes down to which one is more convenient for you. Not sure which one you prefer? Keep reading!
First, we want to start out by telling you a little about menstrual cup cleaning. It’s so important to keep your cup sparkling clean at all times because your vaginal canal is one of the most sensitive parts of the body.
There are two different things you should do each cycle to keep your menstrual cup clean: clean your cup between each use, and sanitize your cup before and after your cycle.
Sanitizing is completely different than cleaning, but equally important! Before and after each cycle — both when you get your menstrual cup out for your period and when you put it away again — you need to make sure all bacteria is removed from your cup. This keeps your cup clean and stain free. It also helps prevent odors.
There are two different ways you can sanitize your cup. The most common method is boiling your cup, but many cup users find that they prefer steaming. They both do the same thing, so the best option for you just depends on which one you prefer!
Why do you have to boil your menstrual cup?
Boiling your menstrual cup sanitizes it and makes it safe to use. Any time you put a foreign object into your body, there’s a chance you could be exposing yourself to bacteria. Infections from menstrual cups are rare, as long as you use your cup correctly and clean it properly. Boiling your cup before and after every cycle, and washing it between uses, will help keep bacteria at bay.
It’s also important to wash your hands before inserting or removing your cup. You’re more likely to get an infection from bacteria on your hands than from the cup itself.
How often should you boil your menstrual cup?
Boil your menstrual cup twice a month: when you get it out at the start of your cycle, and when your period is finished.
How long should you boil your menstrual cup?
We recommend boiling your cup for about 10 minutes. If you boil your cup for too long, it could cause the silicone to thin and soften over time.
How to boil your cup
Simply put a pot of water on the stove to boil and turn it to high. When it reaches a boil, insert your cup. Make sure there’s enough water to completely cover your cup. Some cup users like to put their cup inside a whisk to keep it from touching the sides of the pot. If you don’t like the idea of using a pot that you cook with, consider buying a small pot to use just for this purpose.
It’s a good idea to stay close to your cup and keep an eye on it while it boils. You might be tempted to wander off and do other things, but we’ve heard stories of people who left their cup on the stove and forgot about it! If this happens, you could burn your cup and ruin it. If you do need to walk away, set the timer on the stove so you don’t forget to come back.
Can you boil your menstrual cup in the microwave?
Many people like the idea of boiling their menstrual cup in the microwave. Using a microwave is often more convenient, especially if you’re living in a dorm room or otherwise don’t have access to a stove.
The answer is yes … sort of. You can sterilize your menstrual cup with water that’s been boiled in the microwave. Don’t put the cup itself in the microwave, or it could damage it.
Fill a large mug with water – not too full or else it could boil over – and put it in the microwave. When the water has reached a boiling point, take it out and drop your cup in. Make sure your cup is submerged and leave it for a few minutes.
Our Pixie Cup sterilizing container was made just for this purpose! It’s collapsible, so it’s discreet and easy to store. It’s also microwave safe. Simply fill it with water and place it in the microwave for a few minutes. Or, you can plan your menstrual cup in the cup and pour boiling water over it. Your cup will emerge sparkling clean and germ-free!
Steaming your cup
Steaming is a relatively new option for menstrual cups. While it has been used for quite some time now to sterilize other silicone products, steaming is new to the menstrual cup world!
Steaming is a hassle-free way to remove 99.9% of germs from your menstrual cup. Our Pixie Cup Steamer makes sterilizing your cup easy!
Steaming your cup has several advantages over boiling. For starters, you don’t have to use your cookware to sterilize your cup. In fact, you don’t have to take your cup into the kitchen at all! This is especially great if you share a house with other people and you don’t love the idea of them seeing your menstrual cup on the stove. The steamer has the appearance of a small humidifier or diffuser, and can be tucked away in the corner of your bathroom counter when not in use.
When it’s time to sterilize your cup, simply place it in the steamer with 5ml of water, replace the cover, and push the button. Your cup will be sanitized in 1-3 minutes while you put on your makeup or brush your teeth. No more worrying about burning your cup if you forget about it on the stove! The more water you add to the steamer, the longer it will run.
The next time you get your period, pop your cup back into the steamer, and it’ll be good to go.
The first key to menstrual cup success is making sure it’s cleaned properly. Sterilizing your menstrual cup before the first use in your cycle and right before you store it for the month is crucial. However, quickly washing your menstrual cup with soap before reinserting is perfect.
How do I wash my menstrual cup?
Ideally, washing your menstrual cup with a synthetic oil-free, unscented, gentle soap is best. Silicone is a substance that withstands tremendous levels of heat, but chemically we have to be mindful of what we use on it. Secondly, we have to be careful of anything that residually could be put into our vagina. Our lady region has a perfect balance — soaps, perfumes and synthetics can severely throw off our pH level, which could result in an infection of its own!
Our Pixie Cup Wash is formulated with your menstrual cup and our va-jay-jay in mind! We have 13 all-natural ingredients that make up our Pixie Cup Wash. No crazy ingredients here — only things that are safe, work and that you can pronounce 😉
Here are our super-safe Pixie Cup Wash ingredients:
Distilled water is water that has been filtered to remove minerals.
Phellodendron (amur cork tree) extract
Fructus Cnidii extract
Radix Stemonae Extract
So now that we’ve talked about ideal soaps and ingredients, let’s talk about what NOT to use when cleaning your menstrual cup!
As tempting as it is to grab your mainstream lady wash from the shower, it’s definitely not a good idea. Just don’t do it. Believe it or not, they are designed to only stay on the outside of your body! (Doctors are starting to speak against them too) Where a menstrual cup is an internal object, it’s best to make sure there is no perfume or residue that could be deposited and cause irritation or infection.
What about Toxic Shock Syndrome? (TSS)
Leaving your menstrual cup uncleaned could lead to infection, which is a rabbit hole that’s not fun. Toxic Shock Syndrome (TSS) is something that is typically associated with tampons. That being said, if a menstrual cup isn’t cleaned completely, it can carry bacteria as well! Meg does a fantastic job of describing what exactly TSS is and how it pertains to you, a tampon and a menstrual cup.
How should I store my menstrual cup?
Be sure to boil or steam your menstrual cup to sterilize it after your cycle as finished before you put it away for the month. Make sure that you are keeping it in a breathable bag so it doesn’t keep moisture and aid bacteria growth — Steer clear of plastic or airtight containers!
Now… how about keeping a bottle of our Pixie Cup Wash on hand so you’re never without a perfect + safe option?
