I understand that NASA does it's best to prevent probes and rovers from carrying microbial material from earth and introducing it to target sites, but is it even possible to prevent this type of contamination?

You seem to be asking if perfection is attainable and the answer to that is obvious.

The actuality is more like taking some sensible measures to change the probabilities, a bit like the wisdom of staying home if you are ill with influenza.

There are many aspects of the issue as to what nations of the world have agreed to do and many subtleties. You might start with a survey of what is involved by reading Wikipedia: Planetary protection (https://en.wikipedia.org/wiki/Planetary_protection).

The recent problems with the site erased my post pointing out that the person in charge of overseeing these issues at NASA, Catharine Conley (https://en.wikipedia.org/wiki/Catharine_Conley), has the coolest job title in the world: Planetary Protection Officer. And Swift posted a link to this image (https://what-if.xkcd.com/imgs/a/117/officer.png) at xkcd, so you can see what she looks like (well, sort of ;)).

A good way to clean is on site. Mars is steril enough--but I might want to use the lock-out suits like a Level $ containment area--and clean tools and wear booties when moving to areas where there is water. Clean something down here in this sopu--and some floater will get back on it.
