What cleaner does in Earls Court to some extent (5)
I believe the answer is:
scour
'what cleaner' is the definition.
I can't judge whether this definition defines the answer.
'in earls court to some extent' is the wordplay.
'to some extent' indicates a hidden word.
'SCOUR' is hidden within 'in earls court'.
'does' acts as a link.
Can you help me to learn more?
(Other definitions for scour that I've seen before include "Clean by scrubbing" , "Clean by abrasion" , "Turn upside down" , "Attack with brush" , "Clean abrasively" .)
