Remove suds from broken siren (5)
I believe the answer is:
rinse
'remove suds' is the definition.
(I've seen this in another clue)
'broken siren' is the wordplay.
'broken' indicates an anagram.
'siren' anagrammed gives 'RINSE'.
'from' acts as a link.
(Other definitions for rinse that I've seen before include "Hair preparation" , "Sluice" , "blue one on top?" , "Wash in clean water" , "Use water to remove soap" .)
