First let me say you may not be able to reverse the damage done to the disk, but the method below might help the disc be readable again. If this does work, I would suggest, if possible, you consider making a copy of the disc.
If the CD or DVD contains software, contact the company and they may send you a new disk or send you a link where you can download the program.
Cleaning the CD or DVDPrior to taking the steps to reduce the scratch, make sure the surface of the DVD is clean.
Don’t clean the surface of your DVDs or CDs by wiping them on your clothing. Our clothing can be rough or the disk can rub against a button or a heavy seem on jeans which can cause more scratches on the surface of the disk. You also should not use a paper towel or anything similar as these are too abrasive.
Start by using a bulb air duster (not a can of air, the blast of air is too strong) and carefully blow the surface. I use the bulb duster I bought for my camera. If you don’t have one of these then blow a few puffs of air from your mouth.
Then take a microfiber cloth (or if you wear glasses the cloth you use for cleaning them) and wipe the surface of the disk starting at the center of the disk and work your way towards the edge of the disk.
Reducing the Scratch on Your CD or DVD Using ToothpasteOnce the disk is clean dab a very small amount of non-gel toothpaste (like Crest) on a cotton swab and gently rub in a circular motion over the scratch. You don’t need to use much force, a light rubbing will work.
It will be hard but try and not extend much beyond the scratch as the toothpaste will “sand” the scratched area.
When you’ve finished, gently rinse with cool water until the toothpaste has been rinsed away and dry with a microfiber cloth.
You should notice the scratch has been reduced and/or possible gone. You will also notice the surface where you used the toothpaste is slightly dulled.
If this is your first time trying to reduce a scratch on a disk, you might be super careful when using the toothpaste and not rubbing enough. If after cleaning you see the scratch pretty much looks the same, try using the toothpaste again.
Now try and use your CD or DVD again and see if it works.
