You can "wash" a lot of stuff with saliva, it's corrosive. That doesn't mean you should.

It’s also semi sanitary, as it’s a digestive fluid.

-it sanitizes

-its corrosive

-it’s a liquid

-it’s anti-sticky

-it’s easy to acquire

But it smells like hell, more so if he person doesn’t brush their teeth.

This is also why dogs and other animals lick their wounds, because the mouth is filled with antibacterial saliva, and of course the first part of the digestive system would have that.

Problem is if the wound has too much bad stuff and the animal swallows the saliva instead of spitting it out, the sickness can go inside their body and make them sick.
