She points to the polish (5)
I believe the answer is:
sheen
'the polish' is the definition.
(both can mean a shiny surface)
'she points' is the wordplay.
'points' becomes 'en' (compass points east and north).
'she'+'en'='SHEEN'
'to' is the link.
(Other definitions for sheen that I've seen before include "actor?" , "to the west of Putney" , "Sureface shine" , "Surface gloss" , "Radiance" .)
