Remove stolen contents (4)
I believe the answer is:
wipe
'remove' is the definition.
'stolen contents' is the wordplay.
'stolen' becomes 'swiped' (swiping is a kind of stealing).
'contents' indicates the central letters (I've seen 'content' mean this).
The centre of 'swiped' is 'WIPE'.
(Other definitions for wipe that I've seen before include "Erase recording" , "Clean with e.g. cloth" , "Clean with a damp cloth" , "use cloth" , "Swab" .)
