DIY site Instructables highlights an inexpensive method for breathing new life into those old, scratched CDs you’re still clinging to. Their solution: a dab of Vaseline or any type of petroleum jelly.
A soft cloth or disc cleaner, petroleum jelly, and some ancient scratched CDs are all that is required for this project. Using the disc cleaner/cloth, apply the jelly to the CD. After applying it in a thorough manner, the excess grease needs to be removed. Take a cotton ball, swab it with some rubbing alcohol and start cleaning it off. The idea is that the petroleum jelly will fill in the scratches on the CD, making it—hopefully—readable.
Then again, you’ve got no shortage of methods for fixing those old CDs—we’ve also heard bananas and toothpaste will do the trick—so let us know what methods have worked best for your old CDs in the comments below.
