Should I use RainX or Armor All, or car waxes on my screen?
A. In our opinion this is not a good idea. While the chemical resistance tests shown above indicate that it is not likely to do any direct harm, it is also not likely to offer much of a benefit. None of these treatments will be able to exceed the protection characteristics of your screen’s hard coat. Keep your screen clean and us a proper stylus to protect the hard coat for maximum screen life.
