There's been a lot of discussion re photographing tombstones so when I found this I thought I'd pass it on for what it's worth. The Fuller Brush catalog called "Home Trends" advertises Gravestone Cleaner -- item 35039 $4.95 or 2 for $9. It's supposed to work on everything from cement to marble and terra cotta. I don't know anything about it except that Fuller has always been a good company.
