How can I use Ruby Sterilizer?

The main use of Ruby Sterilizer would be in a microwave.

However, even if we generally can’t recommend using an oven due to the time it takes and the high energy costs, if you don’t have or don’t want to use a microwave and don’t boil your Ruby Cup in a pot, you can also use Ruby Sterilizer in an oven.

No matter where you decide to use the Ruby Sterilizer, please make sure to leave the lid open to create a steam hole.
