I have chronic ocd so I shine and buff my PSP every time I get finish using it. That miocrofiber cloth is a lifesaver. Dampen half of your cloth and wipe every single part of the PSP. Now don't wet the cloth. Just dampen it. Then when you haver wiped the PSP all over with the damp part. Take the drypart and in a circular motion buff the PSP until there are no water smears or marks. I've had my PSP since July 6th and it looks new with the exception of two small scratches on the screen

. They're barely visible though.
