A special treat was to see how the Euston Arch was blackened with soot. All stone was- I remember that vividly from when I was a small boy. When burning coal in grates was banned (smokeless fuel only) I do remember buildings slowly turning white...
My recollection (I lived near Manchester) was that they needed to be specially cleaned rather than slowly turning white of their own accord.
