Prepares for company (6)
I believe the answer is:
cleans
'prepares for company' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cleans that I've seen before include "Tidies up" , "Washes, removes dirt" , "Valets" , "Frees from dirt" , "Washes, makes sanitary" .)
