I need to "spruce up" some tombstones for a special presentation by my museum. They range in age from an 1832 granite block to an 1850 limestone, to a 1970 polished granite block. I don't want to damage them any further with abrasive methods, but they are thick with moss, rotted vegetation is embedded in the deeply carved inscriptions, and one of them is nearly overgrown with grass. Can I use a stiff 100% boar bristle brush, and some sort of gentle cleaner to, at least, make the stones legible again? I will be making a (one-time rubbing) of each, and would like to minimize the possibilty of any damage. Thank you.
