---blankgeputzt : the stock E. equivalent, both in its literal and meteorological sense, is "scoured clean":
All the dishes had been cleared away, the pots scoured clean and set to wait upon the fireless hearth that smelt of cold dead ashes. No one had been cooking ...
... we'd always be family, his voice faltered and tears welled up in my eyes. It snowed in the night. The air was nippy, the sky scoured clean, the land sparkling.
The morning dawned pale, the sky scoured clean and cloudless. “It's pretty,” we said, and yes, the mountains were beautiful that morning. They still are.
In my experience the meteorological metaphor is something one occasionally says and hears.
(Cf. the equivalence blankgefegter Himmel : "sky swept clean")
