Employed in house, dusting (4)

I believe the answer is:

used

'employed' is the definition.
('use' can be a synonym of 'employ')

'in house dusting' is the wordplay.
'in' says the answer is hidden in the clue.
'USED' is hidden in the letters of 'house dusting'.

(Other definitions for used that I've seen before include "Pre-loved" , "Enjoyed" , "not got directly" , "Of clothes or cars, second-hand" , "No longer new" .)

I've seen this clue in The Telegraph.
