Get clean away from the informal London prison! (5)
I believe the answer is:
scrub
'away from the informal london prison' is the definition.
I can't judge whether this definition defines the answer.
'get clean' is the wordplay.
'get' becomes 'sc' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'clean' becomes 'rub' (as in rubbing something to clean it).
'sc'+'rub'='SCRUB'
Can you help me to learn more?
(Other definitions for scrub that I've seen before include "Rough country area" , "Rub hard with a brush" , "Wash with a brush" , "something in the garden?" , "Cancel (informal)" .)
