Step 1: Gather Required Materials.
- Paper towel (softer is better)
- Polishing cloth (eyeglasses cloth will do fine)
- CD scratched beyond playability (Easy to find)
- Can of Brasso Metal Polish.
Step 2: Add Brasso and Start Polishing!
Use the paper towel pieces to polish the CD. Polishing is ideal in straight strokes from the center of the disk to the outside so you polish perpendicular to the tracks on the disc. Because I was short on time, I used small circular motions similar to how I'd polish a car. Take your time with this. Add Brasso when it dries or gets pushed off the CD. Continue this process for about 15 minutes.
You should feel the abrassiveness of the Brasso on the CD as you are doing this. If not, then use a different papertowel. The brasso is removing part of the plastic from the disc not adding to it. You are actually scraping away part of the CD which makes the existing scratches smaller.
After 15 minutes or so, Rince the CD off under water and check the CD. The brasso will have left small scratches on the disc as it wore down the CD. Keep going until the deep scratches are gone, and all that remains are the marks from the brasso. (they will diminish as you continue and get an even surface again).
When done, rince the disc, and wipe it with the soft eyeglass cloth.
Step 3: Insert CD Into CD-ROM Drive and Test.
As you see by my example, I was successful at pulling the data off my CD-ROM.
I have not attempted this on DVDs or video console games. Please do this at your own risk. results will vary on your patience, and polishing technique.
