Works well; however, does vinegar harm cement based pavers?

Being acidic, it *does* attack them; however, weak as it is, it would take
many, many applications to notice anything.

You can kill the moss with a dilute solution of chlorox, don't know if it
does weeds too. Salt - table or rock - should do the weeds and keep them
out for a while once it is watered in, maybe moss too. And as a last
resort, there is always Round-Up

Why is Roundup a "last resort"? It's very safe stuff, and quickly
breaks down harmlessly after doing it's job. It's even approved for
use with food crops. The only caution on the most concentrated version
is that it is an eye irritant. Apparently it's safe to drink right out
of the bottle, as there are no cautions whatsoever against it.

Safer than Clorox.
