Ladies perhaps clean area (8)
I believe the answer is:
washroom
'ladies perhaps' is the definition.
I can't judge whether this defines the answer.
'clean area' is the wordplay.
'clean' becomes 'wash' (washing is a kind of cleaning).
'area' becomes 'room' (room is a kind of area).
'wash'+'room'='WASHROOM'
Can you help me to learn more?
(Other definitions for washroom that I've seen before include "bog across the pond" , "Where Americans go" , "US loo" , "Clean up place" .)
