Street I've tidied up, cleaner (9)
I believe the answer is:
serviette
'cleaner' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'street i've tidied up' is the wordplay.
'tidied up' indicates anagramming the letters.
'street'+'ive'='streetive'
'streetive' is an anagram of 'SERVIETTE'.
Can you help me to learn more?
(Other definitions for serviette that I've seen before include "* [MATERIAL]" , "Table napkin" , "This may give you some protection" , "Consumer protection" , "Personal protection" .)
