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