|Someone has been using a pretty aggressive wire brush(?) at the lower area to clean some of the problems. It's a shame because whatever is being used is really damaging the rock. It scores it with permanent lines and removes all the texture.
Trust me, I get as frustrated as the next guy cleaning moss and grime but a decently stiff nylon brush can get most of it off. Home Depot and Lowe's have plenty of nice tools of the trade in there janitorial aisle. There's really no reason to clean the rock so aggressively, it does more harm than good.
