How do I clean my period cup, step by step?
- Before first use: wash your hands, check that the small air holes around the top are open, and wash the cup. Then boil it for 5 minutes in a pot of water. Make sure it doesn't touch the bottom or sides of the pot.
- Each time you empty it: tip the blood into the toilet, rinse the cup with cold water, then wash it with warm water and Lunette Cup Wash or a mild, unscented soap.
- When there's no sink: wipe the cup with a Lunette Cup Wipe and wash it under running water when you're back home.
- After your period: wash the cup, boil it for 5 minutes, let it air-dry and store it in its linen pouch.
How long should I boil my menstrual cup?
Boil 5 minutes before first use and after each completed cycle. Use a deep pot with plenty of water and make sure the cup doesn't touch the bottom or sides, so the silicone doesn't burn.
Can I sterilise a period cup in the microwave?
Boiling on the stove is Lunette's recommended method. If you use a microwave, put the cup in a microwave-safe container, make sure it is fully under water and never heat it dry, then let the water cool before you take the cup out.
How do I clean the air holes?
Fill the cup with water, cover the top with your palm, turn it upside down and squeeze, so water squirts out through the holes. You can also use a blunt toothpick dipped in rubbing alcohol. Never use sharp items such as needles.
Why does my cup smell, and how do I fix it?
A slight scent is natural. To freshen the cup, wash it with Cup Wash and boil it for 5 minutes. If you notice a strong or unusual odour from your body, check it with your doctor.
Frequently asked questions
Can I put my menstrual cup in the dishwasher?
No. Never put your cup in the dishwasher, and don't use dish soap or detergent on it. Wash it by hand with warm water and Lunette Cup Wash or a mild, unscented soap, and boil it for 5 minutes after each completed cycle.
Which soap is safe for a period cup?
Use Lunette Cup Wash or a mild, pH-balanced, unscented soap. Avoid products with oils, colourants or fragrances: they can leave residue on the silicone and irritate your vagina. If you only have perfumed soap, plain tap water is the better choice.
How do I get stains out of my cup?
Leave the cup in direct sunlight for a few hours, or soak it in lemon juice or vinegar and then boil it for 5 minutes.
How do I know my cup is clean enough?
A clean Lunette cup has no colours, smells or oily residue on its surface. If it still smells after washing, boil it for 5 minutes and let it air-dry.
Everything for cup care: Lunette Cup Wash for daily cleaning and Lunette Cup Wipes for when there's no sink nearby.
