Rubbed out (6)
I believe the answer is:
erased
'rubbed out' is the definition.
('erase' can be a synonym of 'rub out')
This is the entire clue.
(Other definitions for erased that I've seen before include "destroyed the lot" , "'Wiped out, deleted (6)'" , "Rubbed out, expunged" , "Red sea (anag)" , "Rubbed out, deleted" .)
