Former cleaner said it would remove it? (7)
I believe the answer is:
expunge
'would remove it?' is the definition.
I can't tell whether this definition defines the answer.
'former cleaner said it' is the wordplay.
I cannot really understand how this works, but
'former' could be 'ex' (prefix meaning former or onetime) and 'ex' is found within the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for expunge that I've seen before include "Completely remove" , "Obliterate - erase" , "Delete from the record" , "Remove (from records)" , "Annihilate" .)
