In which you may make money and clean up (5)
I believe the answer is:
sweep
'clean up' is the definition.
(I've seen this before)
'in which you may make money' is the wordplay.
I cannot really see how this works, but
'make' could be 'wee' (synonyms) and 'wee' is located in the answer.
'money' could be 'p' and 'p' is located in the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for sweep that I've seen before include "a puppet" , "Use a brush" , "Brush; rush" , "long movement" , "Cricket stroke" .)
