Michael,
Have looked at the stone under a loop.  Try 30x.  Probably burned.
Best,
Leland

Thanks ken about the 48 hour mist in water; but it ain't going to happen
on this project;and for your information the RC Cleaner the other guy
used did not remove the black soots... Pinheads .the limestone is
bleached and blotchy ;and as  hot water washing may ( I said may ) just
bring residual salts and chems to the surface with the dry cycle; I am
reluctant to proceed with taking on this guys contract until Im sure
there are no salts . .do they make big litmus paper....or do I just
stick my tongue on the side of the building.is enough to impress the
client......Best Michael....
