I have called dozens. None of them have any evidence that shaving cream harms tombstones. And the reason they don't is because it is a hoax. As I said before "When in doubt, don't" As I said, I have worked with a stone conservator's company and they know shaving cream to be harmful because of scientific studies. Cite your sources for us. Please advise me of the names of the 'dozens' of stone conservators you have contacted and I will call them myself. Ladies and gentlemen, the pursuit of the truth is worth getting into the very appropriately named 'lather' (good one). Our responsibility to current and future genealogists requires that we act with caution at all times....whether it is old paper, old sources or old stone. This is not a nasty disagreement on my part, merely a stating of facts. If the group prefers (and I do respect your desire to go to another topic), then possibly Esther could respond to this off list. I will be out of town to a museum meeting for the next 24 hours but rest assured I will answer. Yours, Jan
