Cleans with powders (5)
I believe the answer is:
dusts
I believe this is a double definition.
'cleans' is the first definition.
(dusting is a kind of cleaning)
'powders' is the second definition.
'with' is the link.
(Other definitions for dusts that I've seen before include "Removes powder with a cloth" , "Polishes" , "Wipes" , "Cleans a surface with a cloth" , "Performs housework" .)
