Remove soap from broken siren (5)
I believe the answer is:
rinse
'remove soap' is the definition.
(I've seen this before)
'broken siren' is the wordplay.
'broken' indicates anagramming the letters.
'siren' is an anagram of 'RINSE'.
'from' acts as a link.
(Other definitions for rinse that I've seen before include "blue one on top?" , "Use water to remove soap" , "Wash in clean water" , "Run water through" , "Hair colourant" .)
