The two differ in almost everything from the definition to the different methods used. Sterilization involves completely killing the microorganisms on a surface or in a product, while sanitization reduces harmful organisms to ensure the surface is 99.99% free of the pathogens.

Also, sterilization works against every virus together with spores, while some viruses are resistant to sanitization. Besides, sterilization uses very high steam temperatures / dry heat to kill all bacteria, but for sanitization, mostly chemicals containing chlorine or alcohol are used.
