Sterilization

I assume that many people know of the many ways there are to "clean" things, but do they really know what exactly it is they are doing?  Here, I will be briefly discussing 3 ways that are used the most to clean things and what exactly they do.  First of all, I believe that you have heard of sanitize, but do you know what it does?  This basically cleans and disinfects.  For example, when you use sanitizer to clean your hands after using the bathroom.  Second, there is sterilization.  This basically kills all living bacteria.  Last, there is pasteurization.  This process is used as a heating process that kills pathogens.  This is of most importance to humans because it basically cleanses the food you eat.
