Sanitise lists Anglicans put outside (7)
I believe the answer is:
cleanse
'sanitise' is the definition.
(I've seen this in another clue)
'lists anglicans put outside' is the wordplay.
'lists' becomes 'leans' (I've seen this in another clue).
'anglicans' becomes 'ce' (Church of England).
'put outside' means one lot of letters goes inside another.
'leans' inserted within 'ce' is 'CLEANSE'.
(Other definitions for cleanse that I've seen before include "purify from sin" , "Scrub" , "Thoroughly remove dirt from" , "Wash" , "subject to purification" .)
