Top tips before changing your menstrual cup in a public restroom

03_Image of a modern public bathroom


We get it. Youā€™re wary of using public restrooms. Some are super clean and others less soā€”to the point you can almost see germs and bacteria lurking in every corner.Ā 

While there's no safe way to sterilize a menstrual cup without boiling it, thatā€™s something you can do at home between menstrual cycles. During your period, however, you can clean your menstrual cup under any sink or anywhere thereā€™s clean running water. So cleaning it in a public bathroom is perfectly doable.

But we care about your safety, too, which is why weā€™re sharing our sure-fire hygiene tips to clean your menstrual cup in public restrooms:


  • Wash hands before entering a public stall
  • If there are paper towels, wet a couple for hand or cup cleaning, then dispose of them in the waste bin (never the toilet)
  • To keep both hands clean, use tissue or toilet paper to open and close the stall
  • No tissues? Use one hand to open and close the stall and keep the other clean for removing your cupĀ 
  • If your hands are dirty after cup cleaning, use a piece of toilet paper to wipe them down. Use another piece to open the stall. Toss both pieces into the toilet and flush
  • Give your hands a final scrub in the sink


6 ways to clean your menstrual cup in a public bathroom

Now that youā€™re prepared, youā€™ll feel more confident to try these 6 ways to clean your menstrual cup in a public bathroom:


1. Use a water bottle

We know youā€™re worried about not being able to rinse your cup in the safety of your own bathroom without your sink nearby.Ā 

But a simple and safe way to clean your menstrual cup on the go is to keep a small bottle of water with you during your period.Ā 

Once youā€™re inside the stall, set your bottle of water on the floor and open it. Use one hand to remove your menstrual cup and empty its contents into the toilet. With your other hand, take the bottle and rinse the cup with water over the toilet.Ā 

You can also use the clean water left in the bottle to rinse away any blood on your fingers. Then, reinsert your cup and youā€™re done.Ā 


2. Wipe the menstrual cup with toilet paper

You may not always have a water bottle handy when your period arrives unexpectedly.

In this case, use toilet paper or a tissue to clean your menstrual cup. Just remove and empty the contents of your cup with one hand. With your other hand, wipe your cup clean with toilet paper, then reinsert.Ā 

Keep in mind that toilet paper is biodegradable and will quickly disintegrate as it gets wet, with the risk of leaving little bits of paper sticking to the cupā€™s silicone. While you can easily brush away bits from the outside of the cup, removing wet paper from the inside can be tricky.

Instead of rubbing or wiping, try dabbing and blotting to avoid paper breakdown. Though a more delicate motion, patting your cup clean is just as effective and will avoid leaving behind paper residue that might cause infections.Ā 

On days when your blood is thicker or more abundant, one-time blotting may not be enough. Use fresh squares of toilet paper a few times to pat your cup clean. Once back home, you can scrub your cup clean with a soft sponge.Ā 


3. Carry an extra cup with you

What do you do if your period arrives early and youā€™re stuck at the office, or your cup falls in the toilet of a public bathroom? Always be prepared. Having an extra sanitized cup with you is one of the best methods. Since the Ruby Cup is soft, lightweight, and easy to carry, you can hide one in your bag, your pocket, even the glove compartment of your car.Ā 

Next time youā€™re on the move, carry an extra cup for priceless peace of mind. Ruby Cup offers a Duo Pack that you can buy to never be caught off guard again.


4. Use the handicap stall

Nowadays, most businesses and workplaces provide accessible stalls or private bathrooms, all equipped with a sink. While we donā€™t recommend using accessible bathrooms as a norm, they are ideal during that time of the month when youā€™re on the move.Ā 

However, not all disabilities are visible. When youā€™re waiting for the restroom, one best ethical practice is to ask before using the accessible stall to avoid unwanted attention in public lines. If youā€™re in line at the office, be brave enough to ask and explain. Itā€™s the perfect opportunity to share your socially conscious lifestyle with coworkers and promote change.Ā 


5. Reinsert without rinsing

Letā€™s get real here for a moment. How many times have you walked into a public bathroom that had no toilet paper, paper towels, and soap? And you realize youā€™re out of tissues, too...

It happens. But itā€™s not the end of the world. Because if eight hours have passed and you donā€™t foresee having access to a private bathroom anytime soon, youā€™re going to have to make do with what you have.Ā 

Donā€™t think too much about it. If you can wash your hands with water, great. If not, donā€™t worry. Just empty your cup, then reinsert it as is. We know itā€™s not the best method, but itā€™s better to empty your cup in less-than-ideal conditions rather than waiting too long.Ā 

Once youā€™re back home, put your mind at ease and rinse your cup well. You can even use a soft body sponge to scrub away any hard-to-remove buildup that might have accumulated on your cup when you emptied it without rinsing.Ā 


6. Be bold and use the sink

Use the sink. Because once youā€™ve emptied your cup in the toilet, whatā€™s keeping you from washing it as you usually do?

Yes, youā€™re afraid of people seeing your monthly blood and they might stare and gawk at you, but youā€™re not alone because they bleed too. Choosing to use the sink to clean your menstrual cup is the best opportunity to break down the stigma around periods.Ā 

You can transform the conversation.Ā 

Be brave and explain. Because when you share your lifestyle choices with courage and pride, you become an agent of change. And the more you talk about your period with others, the more you turn taboo into normal talk.Ā 

If you fear losing blood as you go from the stall to the sink and back again, donā€™t worry. Studies show that the average menstrual blood per period equals two tablespoons. The maximum amount is a third of a cup. Plus, menstrual blood flows in waves and is not constant, which means youā€™ll have plenty of time to clean your cup without dripping.Ā 

But the best part? The more you use your cup, not only will your confidence using it increase, but youā€™ll gain a better understanding of your menstrual flow.

Maybe youā€™ll opt for lighter flow days. Or, to be extra safe during heavier flows, youā€™ll pad your underwear with toilet paper to prevent spotting as you move between stall and sink.Ā  Whichever time you choose, be bold and wash your menstrual cup in the sink. You got this.Ā 


Live the change you want to see in the world

Now that you know how to clean a menstrual cup in a public bathroom, youā€™re free to keep your active lifestyle intact. And to lead the way for others to follow.

Youā€™re ready to be a game-changer because you know that cleaning your cup in public restrooms isnā€™t as scary as it first seems and is downright liberating. And when you let other people see you owning your healthy lifestyle choices, you empower them to do the same.Ā 

Now, use these key takeaways to live your zero-waste periods on the go:

  • Protect the environment wherever you go.
  • Use best hygiene practices to avoid infections.
  • Keep a water bottle with you during that time of the month.
  • Carry an extra cup for emergencies.
  • Use toilet paper to pat your cup clean.
  • See no paper, think no problem. Empty, then reinsert. Scrub later.
  • Use accessible stalls when theyā€™re free (ask first).Ā 
  • Rinse your cup in the sink and share your zero-waste lifestyle.
  • Free yourself and others from period stigmas.
  • Enjoy the freedom of using your cup anytime, anywhere.


FAQs about how to clean a menstrual cup in a public bathroomĀ 

How do you clean a menstrual cup discreetly?

To clean a menstrual cup discreetly, keep a small water bottle hidden in your bag.Ā 

When youā€™re safe behind closed doors, remove your cup and empty its contents in the toilet. Then use your water bottle to rinse the cup over the toilet. When you donā€™t have a water bottle handy, toilet paper is another discreet option to clean a menstrual cup.Ā 


How do you sterilize a period cup on the go?

Boil your cup in a small pot or the Ruby Sterilizer if you have access to an oven or microwave.Ā 

If sterilizing your cup in boiling water isnā€™t possible, wash your cup under running water, store it, then sterilize when you can. Remember, you only need to sterilize your cup between periods, or if it falls in the toilet or on the floor. Otherwise, just empty, rinse with water, and reinsert.


Is it a good idea to clean your cup with wet wipes or menstrual cup wipes?

We donā€™t recommend using wet or menstrual cup wipes because:

  • most wet wipes are not biodegradable.
  • all wipes create unnecessary waste.
  • menstrual cup wipes are designed to clean the cup, not your vagina.Ā 

To avoid creating waste or risking infections, steer clear of wipes.


Are menstrual cups good for travelers?

Menstrual cups are ideal for travelers. Hereā€™s why:

  • save luggage space,
  • save money you could use for museums or tours,Ā 
  • save time to sightsee instead of searching for drugstores,
  • save your peace of mind to enjoy your trip,
  • save the environment.

Also, the Ruby Sterilizer is the perfect solution for sanitizing during travel as itā€™s discreet, microwaveable, and foldable.

What to do if your menstrual cup drops on the floor or in the toilet of a public restroom?

When you drop your cup in the toilet or on a public bathroom floor, donā€™t use it again until you can sanitize it. Fish it out and wrap it in a paper towel or in the cotton bag that came with your Ruby Cup. Then store it until you can boil it again.Ā 

Carry an extra cup with you for emergencies. Better to be safe than sorry.
