There are several different ways you can sterilize your menstrual cup. You may have seen new UV menstrual cup sterilizers on the market and maybe you’re wondering what they’re all about; whether they work and actually eliminate bacteria! What is UV sterilization?Is it effective for bacteria and viruses? If you found this post, chances are you are doing your research. Let’s dig in!
What is UV Sterilization?
UV light has been used for sterilization and disinfection as early as the mid-20th century, actually! Technology has advanced since then, and specifically in the UV bulbs themselves. Their reliable, long lifespan (thousands of hours) and smaller size has broadened the use! You can find it being used to disinfect water, air, fruits, vegetables, surgical utensils, tablet computers, toys, even fish tanks!

How effective is UV Sterilization?
Scientists have known for decades that broad-spectrum UVC light, which has a wavelength of between 200 to 400 nanometers (nm), is highly effective at killing bacteria and viruses by destroying the molecular bonds that hold their DNA together. This conventional UV light is commonly used to decontaminate surgical equipment.
Within the last handful of years, researchers at CUIMC figured out that a narrow spectrum of ultraviolet light (technically) called far-UVC could kill microbes without damaging healthy tissue. Crazy right? We hear UV and we automatically think of having a gel manicure or spending time at the pool with a lot of sunscreens!
Moreover, the researchers demonstrated that UVC light was effective at killing MRSA (methicillin-resistant Staphylococcus aureus) bacteria, a common cause of wound infections!
What is the difference between the UV rays?
Light is a crazy thing! On one end of the spectrum, you find infrared and on the other end, you find x-ray. The sweet spot in the middle is the visible light; this is what’s able to be seen by the naked eye. Between visible light and x-ray, you find all the UVs.
UVA: UVA rays, which account for 95 percent of the radiation that reaches the earth’s surface, cause wrinkles, “sunspots,” and other types of premature aging. They are also strongly linked to skin cancer.
UVB: UVB rays, which affect the skin’s top layer, cause skin cancer, and most sunburns.
UVC: These rays are considered the bad boys of the UV family. They physically actually never reach the earth’s surface from the sun because it’s blocked by the ozone layer. However, it’s been recreated here on earth with things like mercury lamps, bulbs, and welding torches. UVC light is able to cause the physical destruction of viral, bacterial, and fungal cells in a matter of seconds.
How long does it take for UV light to sterilize?
A matter of minutes! UV-C is the killer of the UV family. Tests of UVC on surfaces have demonstrated that it kills C. diff spores in seconds versus hours for chemical cleaning. In fact, Here at Pixie Cup, we are super excited about the launch of our new UV Sterilizer! By placing your Pixie Cup in the sterilizer and closing the lid, you hit the button and 99.9% of bacteria are killed in minutes. (2 minutes to be exact!) The UV lights remove odor-causing bacteria along with gross things like Staph, Salmonella, E. coli, flu & other common germs. Your cup is clean + safe to be used immediately or stored away for next month!
To use our sterilizer, be sure to wash your Pixie Cup and dry it completely. We recommend our Pixie Cup Wash, which is specifically formulated to gently wash your silicone menstrual cup. On top of that, the Pixie Cup Wash is pH balanced so that it doesn’t interrupt the vaginal flora! Sterilizing your menstrual cup regularly is key to keeping germs + bacteria away and infection at bay.

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.
Sterilizing your menstrual cup is key to extending the life of your cup as well as making it safe to use. One of the best features of a menstrual cup is that it can safely be worn for up to 12 hours (this does depend on your flow as well.) With this in mind, a quick wash during the day is just fine… remember, we’re shooting for a low-stress, low maintenance period!
With all the buzz about BPA and the rise of different reusable materials, it’s important to know what touches your body and what you put in it. Menstrual cups are made from medical-grade silicone. This has taken the worry out of using it inside our bodies and is super easy to keep clean! Here are all the how-to’s!
How do I clean my menstrual cup for the first time?
Yay! Your new menstrual cup arrives. You’re nervous and excited. It’s like a blind date. But messier. You’ve opened it, now what? Boil it! Boiling for approximately 5 minutes is a simple way to ensure your cup is completely clean and ready for use! Make sure your pot has enough water so the menstrual cup is able to float around.
Life hack: squeeze your cup into a whisk and submerge in the water. This protects your cup from harsh contact with the bottom of the pan, which could damage it.
Picking a wash that’s formulated both for the safety of your cup and for you is best. Check out our Pixie Cup Wash for a gentle option! The foamy soap is made from plant-based ingredients and is designed to not harm the vagina or pH levels. If our Pixie Cup Wash isn’t available to you at the moment, make sure you pick something that doesn’t contain dye, oils or harsh chemicals. Fragrances are also a no-no for our lady region!
Rinse with warm water and apply cleanser. Rub around between fingers until yucky residue is gone.
Fill the cup with water and cleanser, place your palm over the top to create a seal and SQUEEZE! This forces water and soap to exit through the suction holes around the top. If stubborn stuff is still in the holes, dip a toothpick in rubbing alcohol and gently poke.
Keep your Pixie Cup Wash in the shower! Empty and clean your cup in there to keep the mess contained!
Cleaning your menstrual cup with soap and water every time you empty your cup is just fine. However, when you’re wanting to put it away for the month or pulling it out to use, you need to sterilize. When done properly, sterilizing eliminates all bacteria so nothing continues to grow.
Medical-grade silicone is quite cool. It’s gentle on us, yet rugged enough to have little staining and is heat resistant up to 500 degrees Fahrenheit. Boiling your cup is the most common way of sterilizing. If you don’t have a stovetop available to you, our Pixie Cup Sterilizing Container makes microwaving your menstrual cup super easy! Fill ¾ with water, place your menstrual cup inside and place the lid on top, but don’t snap it on completely. Leave a space so air can vent through safely.
Do you have roommates? Are you going to visit relatives soon? Or maybe you’re not keen on using the same kitchen items to boil the menstrual cup that you use to cook with! We hear you! The Pixie Cup Steamer is a quick 3-minute fix for sterilizing and can be done while you’re finishing getting ready or pouring yourself a coffee. It only takes a few inches of space on your bathroom counter or bedroom dresser. Be sure to follow the included directions to safely steam your cup. This is a great way to sterilize your menstrual cup without boiling.
How do I clean my menstrual cup in public?
Keep in mind, your Pixie Cup is designed to stay put for up to 12 hours, but life happens and we all find ourselves in less-than-desirable circumstances! Our favorite option for this is our Pixie Cup Wipes. Don’t carry a purse? These packets are slim so you can slip one in your wallet or clutch no problem! Our wipes are biodegradable and flushable so you can flush and go.
What about menstrual cup stains and odor?
Sometimes no matter what we do, there is a lingering odor. Makes sense, right? Your menstrual cup has a dirty job! Making a quick odor-eliminating rinse with items you typically have in the house is an easy fix.
Stains happen everywhere — on our favorite shirts, shoes, bags and you guessed it: our menstrual cups. Getting rid of stains is possible! We also shouldn’t underestimate the power of the sun that we have every day. Set your cup directly in the sun for the day and give it a good sun-soaking before you put it away in the dark for a month!
When do I need to replace my menstrual cup?
A menstrual cup is safe to use for up to 5+ years… technically. That being said, the care and keeping of your cup plays a heavy role. Make sure you’re sterilizing regularly and using the correct type of soap on your cup to prevent drying and cracking. If you notice any sort of cracking in your cup or the outside has become tacky to the touch, discard immediately. At this point, the silicone has been damaged and shouldn’t be used any longer. The most eco-friendly way of disposing of your menstrual cup is to burn it, believe it or not! Toss it into the woodstove or the next bonfire. It doesn’t produce toxic fumes and burns to a simple ash!
Our Pixie Cup Steamer takes the worry and work out of sterilizing your menstrual cup! Add water, place your cup, put on the lid + click the button. Now, put on some mascara and throw your hair in a top knot — go rock your day!
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’ve made the stand to live free. Still, they can be an eyesore. We’ve added a method on removing the stains and some tips on preventing them in the future!
How do I clean off any initial staining?
If your cup is dingy or has staining, let it soak 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 scrub.
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 them! 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.
