Uses Polish enthusiasts? (5)
I believe the answer is:
buffs
I believe this is a double definition.
'uses polish' is the first definition.
(buff can mean to clean with polish)
'enthusiasts?' is the second definition.
(I've seen this in another clue)
(Other definitions for buffs that I've seen before include "Enthusiasts" , "Experts" , "Aficionados" .)
