A scratched DVD with Pledge

My Tip: Smooth A scratched DVD with Pledge

My DVD Player stopped short and said, "Error reading disc. It may be scratched or dirty." Rats! A thorough wiping and several more tries yielded the same result. On close inspection, the disc was indeed scratched.
This past MacGyver tip suggested using toothpaste to fix the disc, but I wasn't sure I had the right toothpaste (Mentadent.) Commenter cenoxo had said:

Spray a little Pledge furniture polish onto the scratched CD, then gently wipe it all off with a soft micropore cloth (the kind used for eyeglasses). Just like on furniture, the clear wax should fill in the scratches and make the CD playable.
