Things You'll Need
Instructions
Dampen a soft, lint-free cloth in warm water. Make sure the cloth is thoroughly rung out. If it's too wet, the water could drip into your PSP and damage the console. Adding soap to the solution is optional. If you decide to add soap, only use a very small amount.
Wipe the screen protector gently while it is still on the PSP, using circular motions to make sure you remove all the dust and fingerprints. Make sure you don't remove the screen protector. If you do, you should replace the old protector with a new one, as reapplying the protector a second time will be tedious and difficult due to typical wear. Fortunately, screen protectors for the PSP are inexpensive.
Dry the protector and your PSP using a soft, dry, lint-free cloth. Use this opportunity to clean the rest of your console, gently wiping away fingerprints and other debris.
