Bled every one in it white (8)
I believe the answer is:
bleached
'white' is the definition.
(thesaurus)
'bled every one in it' is the wordplay.
'every one' becomes 'each' (I've seen this before).
'in it' indicates putting letters inside.
'bled' enclosing 'each' is 'BLEACHED'.
(Other definitions for bleached that I've seen before include "Chemically whitened" , "Paled" , "Whitened or removed colour from" .)
