If your menstrual cup or disc is looking a little dingy, you might be wondering if it’s time for a replacement. In this blog post, we’ll dive into everything you need to know about menstrual product stains, how to prevent them, and how to address them effectively.
Why Do Menstrual Cups and Discs Stain?

Let’s start with the basics: staining is normal. Whether you’ve been using your menstrual cup or disc for a month or several years, it’s bound to develop some discoloration over time. Here’s why:
- Iron in Blood: The iron content in menstrual blood is the primary culprit behind stains. Depending on your iron levels, your product may stain faster or slower.
- Product Texture: Cups or discs with textured surfaces may trap more residue, leading to quicker staining.
- Usage Habits: How long you wear your product during each cycle and how heavy your flow is can also influence staining.
The good news? Stains don’t affect functionality. A stained cup or disc still works perfectly fine, so there’s no need to replace it solely because of discoloration.
Preventing Stains: Tips and Tricks

If you’re looking to keep your menstrual cup or disc looking fresh for as long as possible, here are some preventative measures you can try:
1. Cold Water Rinse
Many brands recommend rinsing your cup or disc in cold water before washing it with warm or hot water. The idea is that cold water helps prevent blood from setting into the silicone. While this method may not work for everyone, it’s worth a shot!
2. Opt for Dark-Colored Products
If stains bother you, consider switching to a black or dark-colored menstrual cup or disc. Darker shades are less likely to show stains, so you can use your product without worrying about discoloration. Brands like Hello Disc, Flex Cup, and Saalt offer black or gray options.
How to Remove Stains from Your Menstrual Cup or Disc

Already dealing with stains? Don’t worry—there are several ways to restore your product’s appearance.
1. Hydrogen Peroxide Soak
One of the most effective methods for removing stains is a hydrogen peroxide soak. Here’s how to do it:
- Use a 2-3% hydrogen peroxide solution (available at most pharmacies).
- Soak your cup or disc for 2-3 hours, ensuring it stays fully submerged.
- Rinse thoroughly and sanitize by boiling or steaming before reuse.
Pro Tip: Some brands caution against using hydrogen peroxide, as it may degrade silicone over time. If you’re concerned, limit peroxide soaks to once or twice a year and always check your product for signs of wear.
2. Manual Scrubbing
If you prefer to avoid chemicals, you can manually scrub away surface stains using a tightly woven cloth. This method requires some elbow grease, but it’s a safe and effective way to restore your product’s appearance.
3. Sunlight
Sunlight is a natural bleaching agent and can help fade stains over time. Place your cup or disc in direct sunlight for a few days, but be sure to keep it in a safe spot where it won’t be disturbed by wind or animals.
When to Replace Your Menstrual Cup or Disc

While stains are harmless, there are some signs that indicate it’s time to replace your product:
- Cracks or Tears: Any damage to the silicone compromises its safety and effectiveness.
- Stickiness or Chalkiness: These are signs that the silicone is degrading.
- Odor That Won’t Go Away: If boiling or soaking doesn’t eliminate lingering odors, it’s time for a new product.
Most menstrual cups and discs are designed to last 5-10 years with proper care, so chances are you’ll lose yours before it wears out!
Final Thoughts
Stains are a natural part of using menstrual cups and discs, but they don’t have to be a dealbreaker. Whether you choose to embrace the “patina” or restore your product to its original glory, the most important thing is that your cup or disc continues to serve you well.
Remember, your menstrual product is a long-term investment in your health and the environment. With proper care, it can last for years, making your period experience more comfortable and sustainable.
