Things You'll Need
Instructions
Open the lid to the PS2's disc tray.
Spray the lens with a few quick, short bursts of compressed air, keeping the nozzle several inches away from the lens.
Apply a small amount of lens cleaner or isopropyl alcohol to one end of a cotton swab.
Rub the damp end of the cotton swab against the lens in a gentle, circular motion, for roughly 10 seconds. Be incredibly careful and use a miniscule amount of pressure so you don't accidentally scratch the lens.
Dry the lens using the opposite end of the cotton swab.
