The demand for headstone cleaning and maintenance depends on your local area. Gravestone caretaking businesses tend to provide services throughout a state or region and do so by appointment only. People may alternately clean and maintain a gravestone themselves, or pay a cemetery caretaker to do so.
Good sources of information for cleaning, maintaining and restoring gravestones are local gravestone associations. They commonly advise against power washing and using harsh brushes and chemicals, since many gravestones contain minerals and salts which tend to erode easily. Specific cleaning methods depend on the material the gravestone is made of. Metal, for example, cannot allow rust removal.
