Hello! The tuckpointing was redone on my 1929 limestone porch 3 days ago. I am noticing some mortar haze on some of the limestones, which I'd like to clean off. I don't know how soon it is safe to clean the stones, or what type of cleaner to buy. The only kind of cleaner I know if is muriatic acid. Has anyone taken care of this type of issue before?
