Things You'll Need
Instructions
Pry off the hard drive cover using your fingertip. Unscrew the unit, using a Phillips-head, and remove the hard drive from the PS3. Wipe the hard drive with a soft cloth, and set it aside.
Remove the rubber feet from the bottom of the console, using a small flat-head screwdriver. Take out the visible screws, using a Torx driver. Remove the cover by sliding it.
Unscrew the remaining seven screws, and gently pull apart the casing.
Rub down the inner workings of the PS3 with a soft, lint-free cloth.
