Ladies note cleaning implement (6)
I believe the answer is:
loofah
'cleaning implement' is the definition.
'ladies note' is the wordplay.
'ladies' becomes 'loo' ('the ladies' is a type of loo or toilet).
'note' becomes 'fah' (fourth note in sol-fa notation, anglicized version).
'loo'+'fah'='LOOFAH'
(Other definitions for loofah that I've seen before include "Dry sponge used for scrubbing" , "Part of fruit used as bath sponge" , "Dried part of plant used as a bath sponge" , "Bathroom sponge for washing back" , "Bathroom scrubber" .)
