Review on Revitalize Cell Phone LCD Screens: Displex Plastic Polish Scratch Remover + Microfiber Cloth by Wendy Key

Instructions in German, that's how it is written (as far as I know): 1) Cover the display with adhesive tape on all sides so that there are no painted surfaces, only the transparent part of the display can be polished. 2) Give the display some DISPLEX. 3) Polish out light scratches with a cotton swab or cotton cloth applying light pressure. 4) Repeat application several times for deep scratches. 5) When removing deep scratches. , smudges may appear on displays with tempered surfaces. Here, buff the entire display until the hardcoat is removed from the entire masked area.
