At first I was very suspicious of what the Display Polish concerned. She was around a long time, because I do not trust them with my phone apply. And there had been on the very large display (Nokia 3650) after a year many scratches accumulated (even by a key, which I had with the phone in your pocket). Eventually I bought a new upper shell and decided on the old Displex ausuzuprobieren. As in the manual I did then: * Apply a drop or two Displex * Take a piece of cotton wool and * With good pressure the entire (!! Important - otherwise it gets bumpy course) Display 2-3 minutes polish My tip: Always alternately rub: circular, horizantal, vertically. After 3 minutes, cotton pad peaceful change and display that long buff until no display polish is left. DONE. And what can I say: The Oberschlale which already well over a year now old, looks "almost" as good as new. Safe on closer inspection are a few to see minor scratches, but when the backlight is eingeschlatet, we see nothing that could spoil the look yet. Edges or protrusions are NOT doing to recognize.
