Quick answer
To use a menstrual cup sterilizer, fill the glass with water, place your cup inside with the tube bent, and microwave for 2–3 minutes with the lid open.
Why use a dedicated sterilizer instead of boiling?
A microwave sterilizer is faster and more portable than boiling your cup on the stove. It uses less water and energy, and you don't need to watch a pot. This is especially handy when you're traveling or sharing a kitchen.
When sterilizing matters most
Sterilize your menstrual cup before first use, after each cycle, and if it's been stored for a long time. Daily rinsing with warm water is enough between uses during your period—over-sterilizing can wear down the silicone over time.
Step-by-step instructions to sterilize your menstrual cup
- Fill the sterilizing glass with water: Pour water into the glass without reaching the rigid edge. Leave enough space so water doesn't overflow when you add the cup. Avoid overfilling—water can splash out during microwaving and cause burns.
- Place your menstrual cup inside: Insert your Eureka! Cup into the water with the tube bent inward. This keeps the cup fully submerged and prevents it from floating. If the cup isn't fully underwater, some areas won't be sterilized. Check positioning before microwaving.
- Microwave with the lid open: Place the glass in the microwave and heat for 2–3 minutes. Keep the lid off to allow steam to escape and avoid pressure buildup. Never microwave with the lid on—it can cause the glass to crack or the lid to pop off violently.
- Remove and let cool: Carefully take the glass out using oven mitts. Let the water and cup cool down before handling. The cup and water will be very hot. Wait at least 5 minutes to avoid burns.
- Rinse and store your cup: Empty the water, rinse the cup with cool water, and dry it thoroughly. Store it in a clean, breathable pouch until next use. Make sure the cup is completely dry before storing to prevent bacterial growth.
