whats a good cleaner to use on a granite headstone that wont damage it.

 

  thanks

You might want to give Simply Green Simple Green a try, it won’t hurt it but might not have enough strength. maybe back it up with a power washer on low – medium depending on psi…

HD, Lowe's etc all carry a cleaner for granite counter tops .  I imagine it is the safest cleaner to use since it's made for granite.  I cant vouch for what the chemicals will to the the grass.
