Polish husband's dated clothing (5)
I believe the answer is:
sheen
'polish' is the definition.
(both can mean a shiny surface)
'husband's dated clothing' is the wordplay.
'husband' becomes 'h' (abbreviation).
'dated' becomes 'seen' (I've seen this in another clue).
'clothing' means one lot of letters goes inside another (some letters cover up or clothe others).
'h' going inside 'seen' is 'SHEEN'.
(Other definitions for sheen that I've seen before include "Surface shine" , "Patina" , "Soft lustre on a surface" , "Radiance" , "Sureface shine" .)
