The disc can be professionally polished and cleaned
no
Most home remedies do not work and there are professional machines that can polish the disc. It is better to replace the disc and not try to remove the scratches
No it does not, many discs can be cheaply replaced with used games rather than trying to repair them
No. You can get a store to buff the disks to minimize the scratches. If they are deep scratches though, it will not work.
you cant
PS2 games are mainly designed for DVD discs, but the PS2 will not play most burnt DVDs
