Put off man using soap (9)
I believe the answer is:
detergent
'soap' is the definition.
(thesaurus)
'put off man' is the wordplay.
'put off' becomes 'deter' (both can mean to discourage).
'man' becomes 'gent' (gent is a kind of man).
'deter'+'gent'='DETERGENT'
'using' is the link.
(Other definitions for detergent that I've seen before include "Cleansing substance used for washing clothes" , "Get tender (anag)" , "Synthetic cleaning substance for washing machines" , "Soapless cleanser" , "help with the washing-up" .)
