I was fixing a hole in my wall with drywall putty, when it was dry I sanded it down and the dust landed directly on the face of my psp, I thought no big deal I will clean it later, but later it was dry and now it is fused into the plastic, I can't get it off, I now have white specs everywhere, I tried to clean it nothing gets it off,,,, need a new faceplate again, I just bought 1 and it was so cheap & ugly.
