sold our house last month. Hired a cleaner to do 8 hrs of cleaning. Got a complaint from the sellers that the house wasn't cleaned to their standards. $%^#$% them.
There was one item left under the stairs(lamp) in the basement and one in the garage(shop vac items) and they made a point that they didn't want them.
From what I understand your supposed to leave the house in the same condition it was in when yhey bought it.... with that said if there's nothing specified in your contract nothing can be done.
