How to remove the bad smell from my menstrual cup

The menstrual cup made of 100% medical silicone , like our GlupCup cup, should not smell like anything because it does not contain toxic materials as happens with tampons or pads. In fact, we are all surprised the first time we smell our menstrual blood after using the cup because it doesn't smell bad, it smells like iron! If you have located this smell and you have seen that it has changed, something is wrong and we are going to explain the possible causes.

Why does my menstrual cup smell bad?

"I have used the menstrual cup for more than 12 hours straight." Skipping basic hygiene rules, such as knowing how many hours I can use the menstrual cup without having to take it off, is a clear indicator that we are doing something wrong. If you use the menstrual cup for 13 hours or more, in addition to being bad for your health, it will affect the smell of your menstrual cup.

"I don't clean my menstrual cup with water when I change it." Another mistake that, although rare, happens on occasion. It is very important to rinse the cup with water whenever you empty it and before putting it back on. When we remove the remains of blood from the cup, we see that it rots when it comes into contact with oxygen from the outside.

"I keep my menstrual cup in a plastic container." The menstrual cup must always be stored in a breathable fabric bag so that it is kept in perfect condition, like the one we deliver with each GlupCup cup.
