Soap, perhaps, for Mr Bloggs (3)
I believe the answer is:
joe
'bloggs' is the definition.
(as in Joe Bloggs, term for an average man)
'soap perhaps for mr' is the wordplay.
I cannot really understand how this works, but
'mr' could be 'jo' and 'jo' is found in the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for joe that I've seen before include "Boy's name" , "-- Bloggs, ordinary man" , "Short for Joseph" , "- Bloggs; - Public" , "-- Orton, playwright" .)
