How do I clean my MCUK?
If you look after your MCUK and clean it well, it should last for years and years.
First use and between periods
Before you use your menstrual cup for the first time and after you’ve finished your period, we recommend giving it a thorough clean. To do this you can
- boil it immersed in water for 5 to 7 minutes (in a pan you use just for this purpose)
- use sterilizing solution or tablets. These are commonly used to sterilize baby equipment. Follow the manufacturer’s guidelines for dilution and soak for the minimum recommended time. Then rinse thoroughly with clean water.
Cleaning your MCUK during your period
When a sink is at hand:
- Wash your MCUK with water or mild, non-perfumed soap. Always rinse it well with water after using soap as any traces left on the cup may cause irritation.
In public restrooms or at work:
Wash your hands at the sink and then either
- take a small bottle of water into the bathroom stall with you, empty your menstrual cup into the toilet bowl, rinse with a small amount of water and re-insert; or
- wipe the MCUK with toilet paper and re-insert.
Remember, because the MCUK tends to hold more menstrual blood than tampons or pads you may not need to empty and reinsert it as often as you would change your conventional sanitary protection.
Follow the same instructions as above but make sure you use drinking water to clean your MCUK.
DO NOT USE THE FOLLOWING AS THEY MAY DAMAGE YOUR MOONCUP OR CAUSE VAGINAL IRRITATION:
- Petrol based substances such as Vaseline
- Oil based substances
- e.g. essential oils or coconut oil
- Harsh cleaners
- Strong or scented soaps
- Dishwasher or microwave
Keeping the holes clear
The holes need to be completely clear to get the best seal possible between the MCUK and the wall of the vagina. If the holes become blocked with menstrual blood/debris then they will need to be cleared.
How to unblock holes:
To unblock the holes, fill the MCUK with water and force the water out of the holes by blocking the entrance of the collecting cup with the palm of your hand. Alternatively you can gently clean the holes using a small brush such as a toothbrush.
How do I remove staining on my menstrual cup?
It’s normal to get some staining on your MCUK over time – as long as you’re following the instructions above, it doesn’t mean that it isn’t clean. However, if you want to get rid of stains, you can
- soak your menstrual cup in sterilizing solution or tablets, following the manufacturer’s guidelines for dilution and soaking for the minimum time; or
- use baking soda. Get a clean, damp cloth or a toothbrush with plenty of baking soda and rub it onto the stained area.
Once you have cleaned your MCUK in this way, rinse it thoroughly with clean water.
How do I remove a strong odor from my menstrual cup?
The MCUK should not have a strong odor so if it does, please see our section on MCUK and Odor to work out why this has happened.
