"Manky", I recall from National Service in early 1950s, was the common, non-regional, army adjective for insufficiently clean and smart kit.

"Clarty" {& associated verb "clart" ~ as in

"We're down here in t'cellar ay, where muck clarts up t'winders;
We've burned all our coals up & we're now burning cinders.
If landlord he do come then he'll never find* us;
For we're down here in t'cellar ay, where muck clarts up t'winders"

which I learned from an army & Cambridge friend from Salford, Lancashire}

appears to be quite widespread Northern English as well as Scots.

*[pron with short 'i']
