industry

I'm a little stuck... Click here to teach me more about this clue!

'diligence' is the definition.
(synonyms)

'home evidently not cleaned without right' is the wordplay.
I cannot quite see how this works, but
'home' could be 'in' (to be in is to be (at) home) and 'in' is located in the answer.
'right' could be 'r' (common abbreviation) and 'r' is present in the answer.
The remaining letters 'dusty' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for industry that I've seen before include "Manufacturing enterprises" , "Hard work" , "Work (of manufacturing)" , "Business" , "The manufacture or production of goods" .)
