Carl Rock wife Manisha was all praise for the across the border experience, people here must be feeling blushed, like Pakistanis have the Tahzeeb, the etiquette, the language was beautiful, very clean as well.
from here:
Actually what such appreciation do is that now people have to prove that she was right, and they have to make it a point.
Pakistan overall is cleaner than India in general, but some areas like parts of Karachi, Lahore others aren't. Also the population density is almost half that of India, the northern belt the Pashtun areas are cleaner, Islamabad is very clean, Lahore has a proper solid waste management setup.
Gilgit Baltistan is very clean...
So overall this is true.
