Instructions
Clean the game disc with toothpaste. Apply the paste to a cotton swab and gently rub the swab against the scratch (rubbing outward from the disc's center) until you have wiped away the scratch as best as you can. Wash the disc in water afterward and dry it with a very soft cloth.
Apply a commercial cleaning solution designed for CDs and similar discs. Follow the packet's instructions for using the substance; it usually involves applying the solution to the surface and rubbing it across with the included cloth in an outward direction.
Switch to other possible solutions if the above substances didn't work. Some examples that can work include an auto interior cleaner like Armor-All, furniture wax like Pledge, a brass polish or petroleum jelly like Vaseline. Wipe the substance outward with the cloth and wash the disc afterward, like with the cleaning solution.
Locate a video store that can refinish the disc if the scratches are too large to remove or none of the the above methods work. These stores can have finishing machines where the fee they charge for using it will still be much less than replacing the disc.
