Areas of vegetation around Crosby getting cleaner (9,5)
I believe the answer is:
scrubbing brush
'cleaner' is the definition.
(I've seen this before)
'areas of vegetation around crosby' is the wordplay.
'areas of' becomes 'scrub' (I can't justify this - if you can you should believe this answer much more).
'vegetation' becomes 'brush' (brush is a kind of vegetation).
'around' is an insertion indicator.
'crosby' becomes 'bing' (singer Bing Crosby).
'scrub'+'brush'='scrubbrush'
'scrubbrush' enclosing 'bing' is 'SCRUBBING-BRUSH'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for scrubbing brush that I've seen before include "Stiff domestic cleaning implement" , "It's used to clean" , "Cleaner" , "One's employed to scour" .)
