Nonionic cleaner such as Woolite or Dawn dish detergent
Water
Plastic or wooden scrapers
Step1
Thoroughly inspect the gravestone for damage. If the stone is crumbling or damaged you should not clean it as you could cause further damage.
Step2
Using a plastic or wooden scraper, carefully remove as much lichen and other biological material as possible.
Step3
Mix a few drops of Dawn dish soap or a cap full of Woolite in a gallon of water.
Step4
With a soft natural bristle brush begin to scrub the stone starting from the bottom of the stone and working your way up. A circular and random motion is recommended to avoid markings on the stone. Scrub as gently as possible to get the job done. Frequently rinse off the brush in the water and soap solution.
Step5
Rinse the stone off with clean water frequently during the cleaning to make sure you are not causing damage to the stone. Do not let the dirty water dry on the stone.
Step6
Once the stone is thoroughly rinsed, pat it dry with a clean cloth.
Tips & Warnings
Always make sure you ask the cemetery's permission to clean a stone, even if the stone belongs to your family.

We photograph headstones/markers for the website: Find A Grave - and NEVER use any liquids on markers for cleaning. Your suggestion to use plastic/wood products for scraping works well for us . . . it is disturbing to see the results of others' use of liquids on stones - permanent discolorations and etchings (probably from bleach) which over time, can totally obliterate markings and carvings. Thanx for sharing what you have experienced in the field!
