Dougie you and you gang might be doing more harm than good, because all that green brownish muck is helping to preserve the masonry, and you could end up breaking pieces off the lettering when you are scrubbing them.
Some only need a little knock to break pieces off, I once leaned my bike against the back of one gravestone in Eccleston and some pieces dropped on to the floor.
