Clear Vision

My landlord is making a house inspection tomorrow, and I have been cleaning frantically in anticipation. Today I cleaned every window and every piece of glass downstairs, expending a bottle of Windolene and a whole pack of J-cloths. By the end of which my arm was nearly falling off. But does my landlord want to see his house as a lived-in home, or a pristine investment? Or is what is important to make your windows clean, that when your landlord comes to see his house, he can see out of it?
