Throat freshener (6)
I believe the answer is:
gargle
'throat freshener' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gargle that I've seen before include "Mouth/throat wash" , "Wash out the mouth and throat" , "Use mouthwash" , "clears the old gorge?" , "Use a throatwash" .)
