Dryer remains (4)
I believe the answer is:
lint
'dryer remains' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lint that I've seen before include "Wound dressing" , "Soft material for dressing wounds" , "Napped cloth used to dress wounds" , "Soft cloth for dressing wounds" , "Fabric for dressing wounds" .)
