Instructions
Place your PS2 Slim in standby mode by holding down the "Reset" button until the LED turns red. Disconnect all peripherals, including power cords, network cables, game discs, game controllers and memory cards.
Use a low-powered vacuum cleaner --- preferably one with a hose --- along the rear-positioned system vents to suck out all the dust from inside the PS2 Slim. Spray the vents with a bottle of canned air and then vacuum again, in the same manner as before, if the dust doesn't come loose at first with vacuuming alone.
Wipe away the dust on the exterior of the PS2 Slim with a soft, dry cloth that you've moistened with a splash of water. Don't moisturize the cloth with any chemical solutions.
