It is a pretty standard and permanent clause in any type of rental property situation that once you are to vacate the property, it should be left in the same condition as it always was. This is why landlords take a deposit from your early on so that these costs can be used in case the property was damaged, however, if you are looking to make sure you get your safety deposit back, you should opt for end of tenancy cleaning services because that is the best way to ensure your money back.
If you are currently in the process of moving, you are probably swamped with a lot of things that need to be done.
