Clean in example sentence
And it means that a building doesn't have to be beautiful to be lovable, like this ugly little building in Spain, where the architects dug a hole, packed it with hay, and then poured concrete around it, and when the concrete dried, they invited someone to come and clean that hay out so that all that's left when it's done is this hideous little room that's filled with the imprints and scratches of how that place was made, and that becomes the most sublime place to watch a Spanish sunset.
