About the only section on the forum to ask:
Apparently there is “limestone†(what I was told) leaching up from concrete (or something) under brick pavers into a door’s metal threshold area; the metal threshold butts up against these outside brick pavers. Is there a decent (safe, cheap, etc) chemical to eat it away/ clean it nicely. Carbonic acid? Vinegar/ acetic acid/ HCl/ muriatic acid. Almost every type of acid dissolves limestone, what would you suggest?

And if I don't see an immediate reaction then ok to letit dwell a while I assume.
I understand it takes water pooling in the area to create this “leaching limestone†problem So solving that drainage issue is a priority.
Thanks
