Things You'll Need
Instructions
Unplug the AC adapter from the wall and remove the battery pack from the PSP. Store the battery pack in a cool, dry environment that is out of direct sunlight and away from the reach of children.
Dip the soft bristle toothbrush in the warm water and use your finger to remove excess water until the toothbrush is no longer dripping. Use the toothbrush to clean around the analog stick and in the cracks between the analog stick and the rest of the PSP.
Leave the PSP to dry completely. Once it is dry, plug the battery pack in. Plug the AC adapter back into the wall socket.
If you still experience problems, go to "Settings," then "System Settings." When the "System Information" screen displays, rotate your PSP analog stick.
