Instructions
Disconnect from all power sources before you clean a PSP to avoid electrical shock. If you need to clean the inside case where the battery is located, remove the battery before you clean the case.
Wipe off the outside of your PSP regularly with a soft dry cloth. A protective microfiber storage pouch can be purchased for the PSP. The PSP can be cleaned while in this pouch by simply rubbing the pouch against it.
Remove any dirt lodged around your PSP controller buttons with a wooden toothpick.
Wipe dirt from the PSP connectors or power cords with a soft dry cloth or a cotton swab. A dirty connector could interrupt the electrical flow to the PSP and inhibit its performance.
Clean headphones or remote control connectors with a soft dry cloth. Dirt in these areas could affect the sound quality.
