Remove wrinkles from (4)
I believe the answer is:
iron
'remove wrinkles from' is the definition.

This is the entire clue.
(Other definitions for iron that I've seen before include "Heavy metal that rusts easily" , "Fe - golf club" , "The metallic element plays a role in the transport of oxygen by the blood" , "sort of club" , "great strength" .)
