Cleaner for PSP

[Ultimate warrior]

Have some smudges and fingerprints on the screen. What should I use so that they are removed and won't damage the screen?

I'd use a good soft cloth to wipe screen over. The ones Sony puts in the boxes of most (if not all) PSP sets are usually good enough for the job. If you don't have one, use something like ones for cleaning glasses' lenses. A cleaner, well I personally use a tad of soap or disinfectant and wipe it over carefully so as not to get the stuff in through the buttons.
