Wash and iron (7)
I believe the answer is:
launder
'wash and iron' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for launder that I've seen before include "Wash and iron linen" , "Make illegal (money) legitimate" , "Led a run (anag)" , "Cleanse (material or money)" , "Perhaps decriminalise" .)
