Believe me, they’re much better clean. The limestone ones, when the sun shines “just so”, seem to be made of gold - which is probably on purpose, considering when they were built Manchester was the centre of the world, richer than London or most other places on Earth.

Better architects of the period understood the effects of soot and played to them. Because houses were heated with coal it was a problem even before the industrial revolution. As such, some architectural historians believe that buildings shouldn’t be cleaned for that reason.
