Hello all. There was a similar thread posted not long ago, but there wasn't much information. I did a little searching, and found minimal info.
Soon, I will be submitting a proposal on some headstones at a very old historic cemetary. Some of the markers there date back to the early 1800's and have NEVER been touched.
I think some of the material is soft and porous limestone instead of granite or marble. Some of the limestone markers are almost black but supposed to be white.
I have been to a couple of sites that may produce promising results, and I plan to make some call Monday, but I wanted to see if anyone here has ever had any jobs like this.
Any chemical recommendations? Special methods? Hot or cold?
Any help would be greatly appreciated. Thanks!
Randy
