Cleaner lot of hair (3)
I believe the answer is:
mop
This could be a double definition.
'cleaner' is the first definition.
(something which 'cleans')
'lot of hair' is the second definition.
'mop' can be an answer for 'hair' (mop can mean a mass of hair). I'm unsure of the 'lot of' bit.
Can you help me to learn more?
(Other definitions for mop that I've seen before include "Bundle of soft material at end of stick for cleaning" , "It's used to wipe the floor" , "Mass of disordered hair" , "Polish" , "Cleaning implement" .)
