Scrape away (6)
I believe the answer is:
abrade
'scrape away' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for abrade that I've seen before include "Day breaks? > Start as before" , "Scratch" , "Shave" , "A beard (anag.)" , "Wear away by rubbing (6)" .)
