This is a contractor's idea of cleaning a mirror. Unfortunately, I tried to fix this right after he left and there is apparently some sort of film on there now. I'm still working on getting it off. As a happy side note, I noticed on his business card that he lives on the same street as one of my friends. I asked this friend if she knew anything about him, mostly to confirm my feeling that I should not allow him back in my house to repaint the ceiling. As it turns out, they make their children steer clear of his house because her husband (who is a mental health professional with experience treating meth addictions) is fairly sure that they are cooking meth there. FABULOUS!
