I am interested in knowing if anyone has done any investigation into the affect of wet grass & weeds, thrown by lawn mowers onto tombstones?
Does this cause some of the biological growths we see on tombstones?
I see this often in cemeteries particularily when the grass has been cut early in the morning while it is still wet.
Is there any data & results showing a “diluted solution of ammonia” for cleaning tombstones? I believe I read where it is not very effective on biological growth, but is it a recommended product for general cleaning of headstones?
When using D2 do the rules apply that say only clean tombstones once every 10+ yrs? Where did this rule come from? I just read it on one of the National Preservations of tombstones sites. Is there data to back this rule?
Has there been any conclusion to the National Cemetery Headstone Cleaning Project and if so where can I find the results?
Thank you for any consideration you give to these questions.
