Maiden happening to scrub old shoe (8)
I believe the answer is:
moccasin
'shoe' is the definition.
(I know that moccasin is a type of shoe)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for moccasin that I've seen before include "Slipper; snake" , "Soft leather 11" , "Soft leather shoe - venomous snake" , "American Indian shoe" , "Venomous American snake" .)
