I'm a little stuck... Click here to teach me more about this clue!

'did his' is the definition.
The definition suggests a singular noun which matches the answer.

'cleaner make it all up?' is the wordplay.
'cleaner' becomes 'char' (charwoman is a type of cleaner).
'make it all up?' becomes 'lie' (I've seen this in another clue).
'char'+'lie'='CHARLIE'
