Flannel and soft soap (8)
I believe the answer is:
flattery
I believe this is a triple definition!
'flannel' is the first definition.
(I've seen this before)
'and' acts as a link.
'soft' is the second definition.
(thesaurus)
'soap' is the third definition.
(I have seen 'Soft soap' mean 'flattery' so perhaps 'soap' could also mean 'flattery')
(Other definitions for flattery that I've seen before include "Blarney" , "Soft soap" , "Honeyed words" , "Mendacious praise" , "Left tray (anag.)" .)
