Ruby Cup sterilizer is fantastic for cleaning your Ruby Cup between your periods. It's foldable and made of 100% food grade silicone.
Put your Ruby Cup inside the sterilizer with water and boil in the microwave or oven.
* Microwave: boil for 2-3 minutes at 1000 Watts
* Oven: boil at 200° Celcius or 390° Fahrenheit for 10 minutes
After it is boiled be careful not to burn yourself - the sterilizer will be very hot. Once the water has cooled down take your Ruby Cup. It is now safe and clean to use.
