Ready for the cleaners (7)
I believe the answer is:
stained
'ready for the cleaners' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stained that I've seen before include "___ glass" , "Soiled" , "Marked, discoloured" , "Church feature - side sold was wanting (anag)" , "Like many church windows" .)
