I don’t think that cloth is going to help you against dust. Most of the dust that gets inside a PS2, gets sucked inside by the fan when it is in use. Air is sucked in the front vents and exits the back. The dumbest move ever made by PS2 designers was to have the air flow over an unsealed CD drive unit and right through a cd laser assembly. Very, very, very dumb design!!!!
I haven’t had a good look at a PS2 laser assembly yet but I’ve worked on many PS1 units and I believe the basic sled design is the same. You have the Laser IC chip mounted on the side of the assembly, the laser beam enters the assembly, hits a mirror to bend the laser 90 degrees up through the focus lens, bounces back off the cd and back to the laser IC chip. Perhaps there is no mirror on PS2 units and the IC is directly under the lens, I don’t know.
I do know this, if you clean the top of that lens, you are cleaning only a fraction of the laser assembly. There is also the surface of the IC, the under side of the lens and possibly a mirror that could collect dust.
Picture this, dust is flying over the surface of the laser assembly, the lens is floating up and down vigorously trying to focus on microscopic pits and at the same time acting like a pump sucking dusty air inside the assembly. It’s not hard to see why lasers go bad after just a few months.
I believe there are filters you can get that snap on the front of a PS2 and also use the USB port to power a fan. It would be a good idea to get one. In fact, Sony should send some to every PS2 owner. It’s the least they could do for being so stupid.
