How To Clean Your Menstrual Cup

Menstrual Cup Cleaning and sterilising your menstrual cup is really simple. There is nothing complicated about cleaning your menstrual cup properly, you can do it simply using things you'd have at home or we stock specialist cleaning products to help.

The difference between cleaning and sterilising is that daily cleaning of your cup only removes some of the surface bacteria and any smells. However, sterilising completely removes bacteria and prepares the cup to be stored until next time it's used.

When Does Your Menstrual Cup Need Sterilsing?

  • When you first receive your cup, you should sterilise it before first use.
  • It is recommended you sterilise your cup at the end of each period.

Methods To Sterilise Your Period Cup

There are a few methods you can use, all are very similar to the methods used for cleaning baby feeding bottles.

Method 1
Boil your cup for 10 minutes in a saucepan on boiling water. You need to keep an eye and make sure that it doesn’t sit at the bottom or touch the sides and it may burn.

Method 2
Using Milton sterilising tablets in a pot of water, leaving to stand as indicated on the Milton instructions.

Method 3
Using a Menstrual Cleaning Cup designed for use in the microwave (adding water so the cup steams).  It is very important you follow the instructions carefully as some menstrual cup brands are not suitable for microwave cleaning.

Emptying & Cleaning Your Cup During Your Period

It's very easy to clean a menstrual cup during your cycle. Keeping your menstrual cup clean can help it last longer and makes sure you avoid infections.

When you go to the toilet if you have a sink available to you, rinse the menstrual cup with cold water (hot water can set stains), then give it a through wash with warm water and then reinsert.  You can do this with just water or you can use a little mild non perfumed, oil free soap, if you prefer. If you are using soap make sure to give it an extra rinse before reinserting to avoid causing skin irritation. We recommend you use a specialist menstrual cup wash designed for use with medical grade silicone cups. Options are Meluna Cleansing Soap  and Saalt Wash these are soaps specifically designed for this purpose.


If you are in a public toilet or have no sink available, where possible take a small bottle of water to rinse out the menstrual cup, wipe with toilet paper and then reinsert it. We also stock Lunette cleansing wipes from as another option when on the go. 

To clean the suction holes in your cup throughly then look at the Me Luna Cleaning Brushes. These enable you to reach every little area where menstrual blood may get dried and stuck.

Menstrual cups usually have a higher capacity than tampons so many people find they rarely have to empty their cup when out and about during to the longer wear time.

Storing Your Cup Between Periods

To prevent mould or damage to your cup, always store it in a cotton bag or other breathable container that will allow for air flow. Keep it well away from lotions, perfumes and other liquids that could damage the cup (or cause you irritation) if they leak.
