If you worry about not wanting to leave your old place unclean, then you have the heart to think of the welfare of the next tenants. As a sign of respect to them, you want their new home to be clean. A clean home or an apartment will paint a smile on their place. They will feel very grateful for you for giving them a warm welcome and that is by leaving the house clean. When it comes to cleaning, you have to be very particular. If you will leave the furniture items, all should be cleaned up, too. Every room should be free of dust and dirt and everything should be placed in order. What will you feel if you see your new place with all the mess? Of course, you will feel disappointed. So, if you don't want to experience such thing, do your job, clean up before you leave. If it is needed, make sure that you also fix everything as well. If the sink is broken or the faucet is leaking, then repair it before you move. This is also one way of giving respect to the new tenants. You can seek the assistance of your landlord or the owner of the apartment to settle all the problems inside the place.
