Polishes fans (5)
I believe the answer is:
buffs
I believe this clue is a double definition.
'polishes' is the first definition.
(buffing is a kind of polishing)
'fans' is the second definition.
('buff' can be a synonym of 'fan')
(Other definitions for buffs that I've seen before include "Aficionados" , "Experts" , "Enthusiasts" .)
