They sanitize, not sterilize.

I'm an RN, and we had to learn all about what I call the "levels of
filth". First, we start with the most clean: "sterile". Defined as the
100% abscense of anything living. Sterile technique is why we can
perform so many surgeries with as low a rate of infection we now
enjoy.

Then from sterile, we talk about the lesser "clean" levels. "Sanitary"
comes just below sterile. Generally characterized by lack of visible
foreign material, and often treaterd with a sanitizing agent such as
chlorinated or quatrinary amonia rinse, or several other accepted
santiizing agents, such as sufficient heat for a sufficient time,
which can sometimes reach the sterile level, but not always.

Then we talk about clean, pretty clean, uncluttered, etc. And on down
to completely filthy!!
