How do you fix a scratched disc with vaseline?

To fix a scratched disc using Vaseline, first clean the disc thoroughly to remove any dirt or debris. Then, apply a small amount of Vaseline to the scratched area, using a soft cloth to gently buff it in. The Vaseline fills in the scratches and can help the laser read the disc more effectively. After buffing, wipe off any excess Vaseline and test the disc to see if it plays better.
