Quick Answer

Use a dedicated menstrual cup steam sterilizer for a quick, hands-free sanitization that takes about three minutes and requires no stovetop or microwave.

Why Steam Instead of Boiling?

Boiling a menstrual cup on the stove works, but it requires watching a pot and risks melting the cup if the water boils dry. A microwave can work in a pinch, but not all cups are microwave-safe and uneven heating can damage the silicone. A dedicated steam sterilizer is designed specifically for menstrual cups, so it uses just a teaspoon of water and shuts off automatically after the cycle, making it safer and more convenient.

How Often Should You Steam?

You should steam sterilize your menstrual cup at the end of each cycle before storing it for the month. A quick rinse with soap and water during your period is sufficient for daily cleaning. The steam sterilizer is for deep sanitization, not for removing blood or debris—always rinse your cup first.

How to Steam Sterilize Your Menstrual Cup

  1. 1. Rinse your cup: After removing your cup, rinse it with cool water to remove blood and debris, then wash it with a mild, unscented soap. The steam sterilizer is for sanitization, not cleaning—any residue left on the cup will not be removed by steam.
  2. 2. Add water to the sterilizer: Measure 5 ml (about 1 teaspoon) of purified water into the base of the steam sterilizer. Do not use tap water, as minerals can leave deposits on your cup. Using too much water can extend the cycle or cause overflow. Use purified water to avoid mineral buildup on your cup.
  3. 3. Place your cup in the device: Open the lid of the sterilizer and place your clean cup inside, open side down, on the designated holder or basket. Ensure the cup is not folded or compressed, as steam needs to reach all surfaces. Close the lid securely.
  4. 4. Start the steam cycle: Plug in the device and press the power button. The cycle will run for about three minutes and then shut off automatically. Do not open the lid during the cycle to avoid steam burns. Wait for the automatic shut-off before opening.
  5. 5. Let the cup cool and dry: After the cycle ends, leave the lid closed for a few minutes to let the cup cool. Remove it with clean hands and allow it to air dry completely on a clean surface before storing it in its breathable cotton bag or container. Store your cup dry to prevent bacterial growth between cycles.
