Over the last three years I've been spraying strength vinegar on my
cement based pavers to kill moss and weeds.

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

Thanks, Gary

Thanks to everyone for your responses. *On balance, it would appear
that vinegar is not the solution to use.

Time to come up with a plan "B".

Vinegar wont hurt anything, it evaporates to quickly and changes from
acid to neutral its interaction, even Muriatic evaporates and looses
its efectivness fast, it doesnt have the time necessary to do anything
but clean the top layer. In stone cleaniing after 5 minutes with
muriatic I find its done its job its deactivated mostly so you wash it
off
