When CDs were released, they were advertised as "indestructible." No one will believe that any more. While you can buy commercial CD repair kits to fix these fragile objects, it turns out there's an easier way. Squeeze that tube of toothpaste and let's get started.

  1. A CD stores information just beneath the label. A scratch that tears through the label usually destroys the CD permanently. Fortunately, scratches are more common on the reflected side, and that's where toothpaste comes in handy. The laser that reads the CD needs to bounce evenly off the smooth, reflective surface. [1] Toothpaste is just abrasive enough to wear down scratched areas to a smoother surface.
    • Small scratches and scuff marks are much easier to repair than deep gouges. Some CD repair services can repair the disc with a special buffing machine, but these are hard to use without causing damage.
  2. Even if you can't see them, tiny flecks of dust on the CD could gouge out new scratches when rubbed with the toothpaste. To prevent this, hold the disc under cool, running water and rub it with a lint-free cloth such as cotton or microfiber. Always rub directly from the center to the edge, never in small, circular motions or along the circular pathways. Only wash the reflective side of the disc.
    • If the CD is very dusty, gently spray it with canned air first.
    • If the CD is visibly greasy, use rubbing alcohol or a CD cleaning solution instead of water.

  3. Only an actual "paste" will work, not a gel. [2] If convenient, choose a "whitening" or "tartar control" toothpaste. These tend to be more abrasive, which will help polish the CD.
    • You might be able to look up your toothpaste brand online to find the "RDA," a measure of abrasiveness. A high RDA toothpaste usually makes a smoother surface, although that's not always true. [3]

Polishing the CD with Toothpaste

  1. As before, a clean rag made from cotton or microfiber is ideal. You can use a cotton swab instead.
  2. Rub the toothpaste over the scratched area. Always move from the center directly to the edge. Repeated movement will slowly wear down the CD, smoothing it out to the level of the scratch. Do not press hard.
  3. Hold the CD under running water. Wipe it with a clean cloth in the same direction of movement.
  4. Be careful, as dry CD is more easily scratched than a wet one. Blot away most of the water first, placing a lint-free cloth directly onto the CD and lifting. Finish by air drying or very gentle rubbing with a dry area of the cloth. As always, rub from the center to the edge in straight lines.
  5. Test the CD once it is completely dry. If it still doesn't function, you can try the same cleaning process with a polish meant for silver, plastic, or furniture. Never use a polish that smells like kerosene or contains petroleum derivatives, as these can break down the CD. [4]

    What can I use in place of a microfiber cloth?
    Community Answer
    You can use an old t-shirt instead of a microfiber cloth. This is what I usually do, and it has not damaged my CDs at all.

  • Question
    Would toothpaste cleaning work on a DVD?
    Community Answer
    Yes, the same things work on CDs and DVDs. Keep in mind that if the scratch is really bad, it may not be repairable.

      Warnings

      • Avoid using warm water. If you choose to run the CD right after the repair, the warm CD may overheat your CD player.

Next, choose a "whitening" or "tartar control" toothpaste, since these tend to be more abrasive. Then, squirt it on a lint-free cloth and gently wipe the scratched area until the scratch is worn down. Finish by washing off the toothpaste under cool running water and drying the CD by blotting it with a soft cloth. To learn how to use stronger abrasive for deep scratches and scuff marks, keep reading!
