answer:When I was young, I used to try to get my cleaning deposit back by spending hours cleaning, only to get letters with no deposit and something like this “I had to hire a cleaning lady to wash the walls of the apartment after you left and this is the itemized bill.” There is no appeal when they claim the apartment was not cleaned to their satisfaction. I only was successful in one appeal, when the landlord said he had to paint the apartment and sent me a bill. I had pictures! But remember, even pictures don’t show if the apartment is clean around the window sills, door frames and cupboards. It is usually not worth the trouble. Just accept the loss of your cleaning deposit as a moving expense.
