Things You'll Need
Instructions
Rinse the UMD under a cool stream of water from the tap. This will remove any dirt or debris that has settled inside the scratches, making them worse.
Dry the surface of the UMD with a soft cloth by beginning in the center of the disc and working your way outward in forward strokes. Do not touch the reflective surface at the center of the disc with the cloth.
Dip the corner of a soft cloth into metal polish, such as Brasso.
Work the metal polish into the surface of the UMD by beginning at the center and wiping the disc outward toward the edges in a straight-line motion. Once again, do not rub or touch the center reflective area.
Allow the metal polish to dry for 5 to 10 minutes, then rinse the UMD under a cool stream of water.
Dry the UMD with a soft cloth, using the same wiping motion.
