Does it make everything sweet and clean? (5,4)
I believe the answer is:
sugar soap
'does it make everything' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'sweet and clean?' is the wordplay.
'sweet' becomes 'sugar' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' means one lot of letters go next to another.
'clean?' becomes 'soap' (soaping is a kind of cleaning).
'sugar'+'soap'='SUGAR-SOAP'
Can you help me to learn more?
(Other definitions for sugar soap that I've seen before include "Paint cleaner" , "cleaning fluid" , "sort of stripper!" .)
