How to Sterilize a Cup

Sterilization is an important task if you have infants or sick family members. There are two main methods to sterilize a cup for these individuals. The easier method is boiling. This will kill most bacteria and viruses, but some are able to withstand even boiling temperatures. The more involved method is the use of a pressure pot, which uses a combination of heat and pressure, and will truly sterilize the cup.
