How to Remove a Scratch on PSP Slim Screen
- 1). Turn off your PSP Slim and clean the screen surface to clear away any dirt or dust near the scratches. You don't want any leftover dust to create more scratches or get in the way of removing the current ones.
- 2). Put two or three drops of display polish onto a clean, soft cloth that won't leave material residue. For example, try not to use a bath towel for this. Instead, use a screen or glass-cleaning cloth.
- 3). Rub the polish in a circular motion into the screen. Use a little pressure, but not too much. Apply enough pressure to work the polish into the scratches, but don't press so hard that you feel the screen beginning to give way to your fingers. Once you see about half of the scratches going away, reverse directions. Rotate directions every once in a while until all the scratches have vanished. If you need to, apply one or two more drops of display polish.
- 4). Wipe off the excess display polish with a clean cloth. If a little residue is left, allow it to dry completely before cleaning it with a little alcohol on a cotton swab or an alcohol wipe.
