This is how we clean War Memorials, with superheated steam from our DOFF machine. Because of the temperature mosses, lichen & algae are removed and the spores killed without damaging the stone. It’s comparatively low pressure vs jet washing and so doesn’t pe*****te plus the temperature means it evaporates quickly.
We don’t use bleach or other chemicals that you may have seen other companies use on projects as these are absorbed and continue to react beyond the cleaning process. This can result in damage to the stone.
So the only thing left to do is repaint the lettering before final inspection
