7 Steps to Clean a Menstrual Cup Properly: Washing, Sanitizing & Storage

A reusable menstrual cup can last for many cycles, but good care matters. The basic routine is simple: keep your hands clean, rinse and wash the cup during your period, sanitize it between cycles according to the manufacturer’s instructions, and store it completely dry in a breathable container.

Different cup brands use different silicone formulas and care instructions, so always treat the directions that came with your specific cup as the final authority.

Cleaning vs. Sanitizing: What Is the Difference?

Cleaning removes menstrual fluid and residue during normal use. Sanitizing is a deeper care step usually done before first use and between cycles, depending on the brand. You do not need to use harsh chemicals to keep a menstrual cup hygienic.

7 Steps to Clean a Menstrual Cup

1. Wash Your Hands First

Before removing or reinserting your cup, wash your hands thoroughly with soap and water. Clean hands help reduce the chance of transferring bacteria to the cup or vaginal area.

2. Remove the Cup Gently

Relax your pelvic floor, locate the base of the cup, and pinch the base to release the seal before removing it. Avoid pulling only on the stem, which is mainly there to help you locate the cup.

3. Empty the Contents

Empty the cup into the toilet or another appropriate drain. If you are tracking your flow, some cups include measurement markings that can help you notice general patterns.

4. Rinse With Clean Water

Rinse the inside and outside of the cup with clean water. Pay attention to the rim and any small air holes near the top, since residue can collect there.

5. Use a Mild Cleanser When Appropriate

If your cup manufacturer recommends soap, choose a mild, fragrance-free cleanser that rinses away easily. Avoid heavily scented soaps, oily cleansers, or products that leave a coating behind.

6. Rinse Thoroughly

After washing, rinse until no cleanser remains. Residue can be irritating for some people, so the cup should feel clean and free of soap before reinsertion.

7. Reinsert or Let It Dry

If you are continuing to wear the cup, reinsert it with clean hands. If your period is over, let the cup dry completely before sanitizing or storing it according to the brand’s instructions.

How to Sanitize Your Cup Between Cycles

Many silicone menstrual cups can be sanitized by boiling, but the recommended time and method vary by brand. If boiling is approved for your cup, use enough water to keep it from resting against a dry, overheated pot surface and follow the manufacturer’s timing exactly.

Some brands also approve purpose-built menstrual cup steamers or sanitizing containers. Use only methods specifically recommended for your cup. Strong household disinfectants are not a substitute for the manufacturer’s care instructions.

Cleaning a Cup in a Public Restroom

If the sink is outside the stall, you can carry a small bottle of clean water to rinse the cup after emptying it. If rinsing is not practical, follow your cup brand’s instructions for temporary cleaning and wash it properly when you have access to a private sink.

Clean hands remain important, so wash before entering the stall whenever possible.

Menstrual Cup Care While Traveling

A simple travel kit can make cup care easier. Consider packing your cup, its breathable storage pouch, a small bottle for clean water, and any cleanser or sanitizer specifically approved by the manufacturer.

If you are somewhere where tap water is not considered safe for drinking, use an appropriate clean water source for rinsing your cup.

What to Avoid

• Fragranced or heavily perfumed soaps.
• Oil-based cleansers that may leave residue.
• Abrasive scrubbers that can damage the surface.
• Bleach or strong household chemicals unless the cup manufacturer explicitly approves them.
• Excessive heat or boiling longer than directed.
• Storing the cup while it is still damp.
• Sealed plastic storage that prevents airflow.

How to Store a Menstrual Cup

Once the cup is clean and completely dry, store it in the breathable pouch or container supplied by the manufacturer. Keep it somewhere clean and dry until your next period. Avoid direct heat, prolonged sunlight, and airtight plastic bags unless the brand specifically recommends otherwise.

When Should You Replace a Menstrual Cup?

Check the cup regularly for cracks, tears, a sticky or powdery texture, changes in shape, or other damage. Light staining alone does not necessarily mean the cup is unusable, but a damaged cup should be replaced.

If you notice a persistent unusual odor or changes in the material that do not improve after proper cleaning, consult the manufacturer’s guidance.

Frequently Asked Questions

Do I need to sanitize the cup every time I empty it?

Usually no. During your period, routine cleaning is generally enough. Follow your cup’s directions for how often it should be sanitized between cycles.

Can I use regular hand soap?

Not every soap is suitable. If your cup allows soap, a mild, fragrance-free cleanser that rinses clean is generally preferable. Always check the cup manufacturer’s care guide.

What if the cup becomes stained?

Some discoloration can happen with repeated use. If the cup is otherwise intact and clean, staining may be cosmetic. Avoid using aggressive stain-removal methods unless the manufacturer recommends them.

What if cleaning causes irritation?

Stop using any cleanser that appears to irritate you and rinse the cup thoroughly. Persistent burning, pain, unusual discharge, fever, or other concerning symptoms should be discussed with a healthcare professional.

A Simple Routine Is Usually Best

Good menstrual cup care does not need to be complicated. Clean hands, gentle washing, manufacturer-approved sanitizing, complete drying, and breathable storage cover the essentials for most reusable cups.
