ELI5: If HIV can be spread through body fluids, why can't it be spread through saliva?

Saliva has very little “bodily” material for the HIV to reside in. Its mostly just water and salt. And as always dose makes the poison, so technically you could get HIV from saliva, but you would need to drink liters of it to even have a chance.
