Why Proper Cleaning Matters
Your menstrual disc is a medical-grade silicone product that sits inside your body for up to 12 hours. Because it's reusable, it's crucial to clean it thoroughly after each use to prevent bacterial buildup and maintain its integrity. Proper cleaning not only protects your health but also extends the life of your disc, saving you money and reducing waste.
The Flex Reusable Disc is made from body-safe, medical-grade silicone, which is non-porous and resistant to stains and odors. However, if you don't clean it correctly, residue can accumulate, leading to unpleasant smells or even degradation of the material. By following a consistent care routine, you can keep your disc looking and feeling like new.

- Always wash your hands before and after handling your disc.
- Clean your disc immediately after removal to prevent staining.
- Use mild, unscented soap—avoid harsh chemicals or fragrances.
Step-by-Step Cleaning Routine for Your Flex Disc
Cleaning your Flex Reusable Disc is quick and easy. Start by rinsing it under cool or lukewarm water to remove any blood. Then, apply a small amount of mild, unscented soap (like a gentle castile soap) to your hands and gently rub the disc, paying attention to the rim and the cup area. Rinse thoroughly until no soap residue remains.
For a deeper clean, you can use a dedicated menstrual cup cleaner or a solution of water and white vinegar (about 1 part vinegar to 3 parts water). Soak the disc for a few minutes, then rinse well. Avoid using boiling water, as it can damage the silicone over time. Instead, opt for a steaming device or a microwave-safe sterilizing bag.
- Rinse with cold water first to prevent protein stains from setting.
- Use your fingers to gently scrub the surface—avoid abrasive brushes or sponges.
- Dry your disc completely before storing it in a breathable cotton bag.
How to Sterilize Your Reusable Disc
Sterilizing your disc between cycles is essential to eliminate any lingering bacteria. The best way to sterilize a silicone disc is to boil it in a pot of water for 3-5 minutes. Make sure the disc is fully submerged and that you use a dedicated pot (not your cooking pot) to avoid any cross-contamination. Let it cool completely before handling.
Alternatively, you can use a microwave sterilizing bag or a UV sterilizer designed for menstrual products. These are convenient and safe options that don't require boiling. Just follow the manufacturer's instructions. Avoid using chemical sterilizing tablets or alcohol, as they can degrade the silicone.
- Boil your disc after your period ends, not during, to avoid water staining.
- Never boil your disc while it's in its storage case—remove it first.
- Check your disc for any signs of wear or damage before sterilizing.
Storing Your Flex Disc Starter Bundle
Proper storage is key to maintaining your disc's shape and hygiene. After cleaning and drying, store your disc in a breathable cotton pouch or the included Flex Disc Case. Avoid airtight containers, as they can trap moisture and promote bacterial growth. Keep your disc away from direct sunlight and extreme temperatures.
Your Flex Disc Starter Bundle may also include panty liners or pads for backup. Store these in a cool, dry place, and always check the expiration dates on disposable items. For your reusable disc, a dedicated storage case keeps it safe and ready for your next cycle.
- Air-dry your disc completely before storing to prevent mold.
- Use the Flex Disc Case for travel—it's discreet and hygienic.
- Keep your disc out of reach of pets and children.
Common Mistakes to Avoid
Many people inadvertently damage their reusable disc by using the wrong cleaning methods. Avoid using scented soaps, antibacterial soaps, or dish soap, as these can leave residue and irritate your skin. Also, steer clear of oil-based products, which can break down silicone. Never use a dishwasher or washing machine to clean your disc.
Another common mistake is boiling your disc too frequently or for too long. While boiling is safe, doing it after every cycle is unnecessary and can shorten the disc's lifespan. Stick to a routine: rinse and wash after each use, and sterilize once between periods.
- Don't use peroxide or rubbing alcohol—they can cause the silicone to become sticky.
- Avoid using a toothbrush or scrub brush, as they can scratch the surface.
- If you notice any discoloration or odor that doesn't go away, it's time to replace your disc.
When to Replace Your Reusable Disc
With proper care, a Flex Reusable Disc can last up to 10 years. However, it's important to inspect your disc regularly for signs of wear, such as cracks, tears, or a change in texture. If you notice any of these, replace it immediately to avoid leaks or discomfort.
The Flex Reusable Disc is a long-term investment in your health and the environment. By following these care tips, you'll maximize its lifespan and enjoy a worry-free period experience. Remember to always have a backup plan, like the Flex Disc Starter Bundle, which includes everything you need for a seamless cycle.
- Replace your disc if it becomes sticky, discolored, or misshapen.
- Keep track of when you started using your disc to estimate its age.
- When in doubt, replace it—your health comes first.
