Are menstrual cups dishwasher safe?
No. Not all menstrual cups are dishwasher safe. There is only a few menstrual cups that can be safely run through a dishwasher without getting permanently damaged. If you want to know for certain if your menstrual cup is dishwasher safe or not- you should first verify it with the manual that was included in your menstrual cup before ruining your menstrual cup.
Absolutely not! Diswasher are made for dishes. The silicone would be fine because a menstrual cup can be boiled and handle very high temperature but the detergents used are not vagina safe.
There are many ways to clean a cup.
I don’t think eating utensils and menstrual cups should EVER be washed together, that is not cool & personally would not want to use those dishes or utensils ever again if I knew this had taken place.
