How can you clean a PS2 game so it won't freeze!?

May be...

I have Grand Theft Auto San Andreas but it keeps on freezing at the start because it has a thew scratches on it is there any way to make it work or a way to get rid of the scratches PLEASE i need your help thankyou so much.

Take the disk to your nearest video shop, and they will repair it fully with money back guarantee

I bought a "Disc Dr." disc resurfacer, it works pretty good.

I've also heard you can buff out small scratches w/ soft cloth & auto wax, but I have not tried it.

just clean the disk with cotton or buy a disk cleaner for the ps2

use rubbing achohol with some soft cloth it works perfectly
