Things You'll Need
Instructions
Power off your PlayStation 2 console and unplug it to avoid accidentally shocking yourself.
Clear away any dust or hair obstructing the lens. Gently spray the area with compressed air to clear excess dust, but never spray the lens directly.
Dampen a cotton swab slightly with rubbing alcohol. Actual lens cleaner and lens cleaning cloths work just as well. Don't dampen it too much.
Rub the lens very gently in a circular motion for ten seconds with the cotton swab. Then use the dry end and repeat for ten more seconds without the alcohol to clear away any dampness and smudging.
Spray the compressed air a few more times if necessary to clear away any dust or grime left in the laser gear.
