Cleaning Gravestones

Cleaning gravestones can be a meaningful way to preserve important historical information. Remember, “If you can read it, there’s no need to clean it.” Here are some tips for cleaning gravestones:

• Timing Matters: Avoid cleaning gravestones until after the danger of frost has passed to prevent water from freezing and damaging the stone.
• Handle Fallen Stones with Care: Never attempt to move a fallen gravestone; leave this task to the experts.
• Cleaning Process:
  • Spray D/2 on all parts of the stone and let it sit for 5-10 minutes.
  • Use a wooden paint stick or plastic scraper to gently remove lichen.
  • For lettering and decorations, use the pointed end of a bamboo skewer or chopstick.
  • Avoid using wire brushes, household cleaning products, power washing, chalk, flour, shaving cream, Windex, dish soap, or vinegar.
• Cleaning Solutions: You can use plain water or purchase D/2 from atlaspreservation.com. If you have questions, consult a professional conservator.
• Tools: Use a pail for wash water and a plastic, nylon, or natural bristle brush. Apply minimal pressure while scrubbing, and rinse with clean water after cleaning. Work from the top down and keep the stone wet to prevent abrasion.
• Fragility Warning: Old gravestones, especially those made of marble and limestone, are fragile. Avoid using force and never use a gravestone for support when standing from a kneeling position. Do not sit on gravestones.
• Cleaning Frequency: Limit cleaning to no more than once every 10 years. Take photographs and note down the information exactly as it appears on the stone, including any mistakes.
• Permission: Always obtain permission from the family or cemetery before cleaning gravestones that do not belong to your own family.

Cleaning gravestones is a valuable way to honor our history, but it should always be done with care and respect for the past and those who have passed on.
