Cadge from a cleaner (6)
I believe the answer is:
sponge
This clue is a double definition.
'cadge' is the first definition.
(I know that cadge can be written as sponge)
'a cleaner' is the second definition.
'from' is the link.
(Other definitions for sponge that I've seen before include "Sea creature often found in bathroom" , "Heavy drinker" , "Sea animal often found in bathroom" , "Absorbent marine organism" , "Bathroom scrubber" .)
