Cleaning up liquid sink has in it (5,2)
I believe the answer is:
quids in
'cleaning up' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'liquid sink has in it' is the wordplay.
'in it' indicates a hidden word (I've seen this in other clues).
'QUIDS IN' is hidden within 'liquid sink has'.
Can you help me to learn more?
(Other definitions for quids in that I've seen before include "Having made a profit" , "Having a profitable situation" , "Likely to profit" , "Better off" , "Profiting from something" .)
