All the chemists aside, I doubt the vinegar, used occasionally in this
manner, would be any more damaging than the normal pollutants in the air or
rain. If it's worked for 3 years with no noticeable impact you are probably
safe to continue.

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
