How do you get a haze off from a mirror?

For a haze on mirrors or glass that nothing works on or if you know that the surface has been chemically "etched" by using the wrong cleaner use jeweler's rouge. Call a local jewelry store to see if they have some in stock (about $4-5 a stick). This is a hard compound that you rub on the surface first then buff with a dry cloth. It can be labor intensive and time consuming, but it has worked when nothing else has. The sticks come color-tinted, but I don't believe that applies for this application- I have used black and white with success.
