Car wash cloth (3)
I believe the answer is:
rag
'car wash cloth' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rag that I've seen before include "Scott Joplin composition, for example" , "University festival or torn cloth" , "Torn cloth or students' shindig" , "Sleazy paper" , "piece Joplin would compose" .)
