What does sterilizing mean?
Sterilizing is the present participle of sterilize and is used both for the act of eliminating living microorganisms and for something that performs that work. In medicine, laboratories, and food processing, sterilizing means destroying all viable microorganisms, including resistant bacterial spores; the process is more thorough than ordinary sanitizing or disinfecting. A sterilizing solution or piece of equipment therefore prepares instruments, surfaces, or materials for use where contamination would be unsafe. The word can also refer to preventing reproduction, as in sterilizing animals or making biological material infertile. Its language is mainly technical and formal, though its meaning is familiar wherever hygiene and food safety are discussed. Sterilizing is especially useful because it identifies a comprehensive process rather than one that merely reduces or removes some microorganisms.
To make something free from living microorganisms, or to render an organism or biological material incapable of reproducing.
"Technicians sterilize the equipment between uses to prevent contamination."
As a present participle or gerund, sterilizing can express an ongoing or completed action.
Denoting the process or means of making something free from living microorganisms.

Where does sterilizing come from?
The word descends through French stérile from Latin sterilis, meaning “barren, unfruitful, or unproductive.” The medical sense of being free from living organisms developed later, and the verb sterilize was formed with the suffix -ize. Sterilizing is the verb's present participle and gerund, while sterility and sterilization continue the same Latin-derived family.
