Destroy; wipe out (10)
I believe the answer is:
obliterate
I believe this is a double definition.
'destroy' is the first definition.
(I've seen this in another clue)
'wipe out' is the second definition.

(Other definitions for obliterate that I've seen before include "get rid of" , "Eradicate" , "Root out" , "Annihilate" , "Destroy all traces" .)
