Dutch dive’s needing a clean (5)
I believe the answer is:
dusty
'needing a clean' is the definition.
(something dusty needs to be cleaned)
'dutch dive's' is the wordplay.
'dutch' becomes 'du' (I've seen this in other clues).
'dive' becomes 'sty' (both can mean a messy or unpleasant place).
'du'+'sty'='DUSTY'
(Other definitions for dusty that I've seen before include "Miller - or answer, may be!" , "Powdery" , "Particle-covered" , "Ms Springfield" , "Needing cleaning" .)
