A: It can happen that the menstrual cup starts to smell unpleasant for several reasons. To make your cup free of any unpleasant scent, there are a few methods you can try out:
- Soak the cup overnight in hydrogen peroxide (3%).
- Mix ½ part water and ½ part vinegar and leave the cup overnight in the mixture.
- Boil the cup by adding a scoop of baking soda to the boiling water. Then place the cup in full sun to let it dry.
Make sure that after one of the above methods you wash the cup again with pH-neutral soap, rinse it with water and then sterilize it in boiling water. This deep cleansing is stressful on the material of the cup, so don’t do it too often.
If the cup still smells after this, there is a chance that the smell cannot be removed from the cup.
