Genealogists and anyone else interested in preserving cemetery tombstones and other objects exposed to the weather should become familiar with D/2 Biological Solution. It is useful for cleaning tombstones without causing any damage to the stone.
The solution is safe for use and does not harm the tombstone. Even the highly-respected Association for Gravestone Studies recommends the product in the organization’s FAQs (Frequently-Asked Questions) at https://www.gravestonestudies.org/knowledge-center/faq-s#faqnoanchor:
“Treat a wet gravestone with D/2 Biological Solution, scrub into a lather using a plastic bristle brush, and smooth the lather into the inscription to make the letters more readable. Afterward, rinse the stone thoroughly.”
