Why I’m Totally OK With Showing Off My 5-Year Old Menstrual Cup

Menstrual cups are revolutionary and a wonderful way to balance your carbon footprint in the right direction, but after a few years they can start to look more lump of coal rather than diamond. Due to the pH environment of the vagina, many women experience staining of their menstrual cups, no matter how clean it is. There are many DIY methods on the internet utilized by women to re-sparkle their cups, but many silicone cup manufacturers don’t recommend anything beyond a gentle soap and perhaps occasional boiling. I decided to risk one of my original menstrual cups on a popular stain removal method using something you probably already have in your medicine cabinet: 3% hydrogen peroxide!

My Lunette Diana (sadly, a limited edition color of the classic Lunette cup) came into my life a lively pop of spring green, but after 5 years had settled into more of a river-bottom, rusty green. Since it’s just a back-up cup these days, I was willing to risk it in an attempt for color rejuvenation… for science! Speaking of science, I referenced this Chemical Compatibility chart which allows you to select a material and chemical and see their compatibility under different environments. Seeing that silicone has an “Excellent” rating with Hydrogen Peroxide at the 10% strength, I was put more at ease with my little experiment because I only had HP at 3% and was going to be diluting it even further with plain old tap water.

After cleaning - it matches this spider plant!

My materials? A clean mason jar with lid, Hydrogen Peroxide 3%, and my dingy cup. I popped my Diana into the jar, filled the jar halfway with hydrogen peroxide, filled it the rest of the way with tap water, then placed the lid onto my jar loosely. This was left on my kitchen counter overnight. The next morning, I emptied the jar and rinsed off my Diana – my beautiful, sparkling, spring green Diana! I was amazed at how thorough the soak was. It even got the tiny suction holes along the rim!

So that is why I’m totally OK with showing you my 5-year-old Lunette. Not all cup manufacturers recommend using this method of stain-removal, so please only do so at your own risk (and do NOT use this with the natural gum rubber Keeper Cup–it can cause corrosion)! I personally won’t use this method of cleansing often as I’m confident in the simplicity of gentle soap and water, but it’s nice to know that it worked well for old, stubborn stains.

Have you ever used a controversial stain-removal method on your cup? What’s your favorite cleanser to use? Are you one of the lucky ones whose cups don’t stain at all?

Until next time!

Absorbently yours,
