A person's good intentions alone do not qualify them to clean historic gravestones. A recent newspaper article reporting damage done to Civil War-era gravestones in Maryland is yet another example of someone who thought it was permissible to alter grave markers to better read the inscriptions obscured by years of growth and grime (I'm giving the unknown person the benefit of a doubt that their intentions were not malicious). Almost weekly I learn of another "good Samaritan" who is inspired to clean gravestones in a cemetery. It is true that proper cleaning can help to preserve stone and that many gravestones stand neglected in cemeteries all over the US. However, before anyone attempts a cleaning project in a cemetery, it is essential to, 1) research proper historic stone cleaning techniques (such as on websites like NCPTT), 2) share your plan for cleaning gravestones with a professional to get their feedback, and 3) obtain permission from the governing body of that cemetery. Without proper training and planning, a person--no matter how big their heart--risks doing more harm than good to that old gravestone they wish to preserve.
