how to sterilize your cup?

I bought a meluna xl soft and it´s floating!! how can I sterilize the cup?

I usually use a plastic container and sterilizing tablet, but my other cups are made of silicone and not float ..

can someone help me??

A good way to sterilize your Meluna is to boil it. I bought a special microwavable cup from the Meluna website. It allows you to boil it in the microwave. Just fill the cup about halfway to 3/4ths of the way, and place your cup inside. Make sure your cup floats to the top. Don't close the container all the way, just about halfway. Microwave it until it boils, and then add up to five more minutes onto the timer. It's quick and easy, and is okay to use on the colored Melunas. Happy cupping!
