Date created: 1st November 2025

Sterilising your my mimi menstrual disc is one of the simplest parts of using reusable period care. Whether you prefer a fast microwave method or traditional boiling water, both approaches keep your disc clean, safe and ready for each cycle.

This guide breaks down the exact steps to follow, how often to sterilise, what products to avoid and how to look after your disc for long-term use.

Why sterilising matters

Sterilising removes bacteria and keeps your disc feeling fresh at the start of every cycle. Because the my mimi disc is made from 100 percent medical-grade silicone, it can withstand heat without breaking down. A quick sterilise once per month helps maintain hygiene and ensures the material stays in good condition across its lifespan.

Option 1: Using the my mimi GO microwave steriliser

The quickest way to sterilise your disc is with the GO microwave steriliser. It’s designed for travel, home use and anyone who prefers a faster routine without boiling water.

Steps

1. Open the GO steriliser and add clean water up to the line inside the container.
2. Place your disc inside the unit, ensuring it is fully submerged.
3. Secure the lid firmly.
4. Microwave on high for 3 minutes. Allow it to sit for a further 2 minutes before opening.
5. Carefully remove the disc and let it air dry on a clean surface.

That’s it. No pots, no steam baskets, no extra equipment. The GO steriliser is compact, lightweight and ideal for people who want a quick, fuss-free method each month.

Option 2: Sterilising with boiling water

If you prefer the traditional stovetop method, your disc can be safely sterilised using boiling water. This is also useful if you don’t have access to a microwave.

Steps

1. Fill a small pot with water and bring it to a gentle boil.
2. Place your disc into a heat-safe strainer or directly into the water.
3. Boil for 5 minutes, ensuring the disc does not touch the bottom of the pot to avoid heat marks.
4. Remove with clean tongs and allow it to cool and air dry.

Do not exceed the recommended boil time, as prolonged direct heat may cause discolouration over time. This will not affect performance but may shorten the life of the silicone.

How often should I sterilise my menstrual disc?

You only need to sterilise your disc at the start or end of each cycle. During your period, regular washing with warm water and a mild, fragrance-free wash is enough. If you prefer a deeper clean between uses during your cycle, the my mimi foaming cleanser can be used daily as it is pH balanced and gentle on silicone.

Products you should avoid

Certain products may damage silicone or cause skin irritation. Avoid:

• Alcohol wipes
• Bleach or harsh chemicals
• Antibacterial soaps with added fragrance
• Oil-based lubricants

If you need a lubricant for insertion, choose a water-based option made for intimate use such as the my mimi personal lubricant.

Can I sterilise the disc inside its carry bag?

No. The carry bag is designed for storage only and is not heat-safe. Always use the GO steriliser or a pot of boiling water when sterilising.

Is the disc safe after sterilising?

Yes. Heat sterilisation does not weaken medical-grade silicone. Your disc remains soft, flexible and safe to use across its lifetime. my mimi discs are also TGA compliant and FDA registered, giving you extra confidence in the material used.

Tips for long-term care

• Store your disc in its breathable pouch rather than an airtight container.
• Let your disc air dry fully after washing or sterilising.
• Keep your steriliser clean by rinsing it after each use.
• Inspect your disc monthly for tears or irregularities.

With regular care, your my mimi disc will last several years, making it a reliable and sustainable choice for reusable period care.
