I tried to clean all the mirrors in my large bathroom but they always looked dusty. This really works and doesn't leave behind little white specs like all the other glass cleaners I use. Maybe it has something to do with the type of cloth that I use but with this I just use a rag and no streaks. Good for cars too, just make sure you rub it in really well or it will fog up when it rains.
