It's a situation that is all too common: You pop your favourite video game disc into your console or computer only find that it doesn't work. When you check the disc out, you realise it has a big crack in it. If the crack is deep, there is usually no hope in saving it. You can repair small cracks, however, with just a few common household items.
Check the disc to find out what the problem is. You may want to try putting other discs in your console to make sure it is just the disc and not the console itself. If it is the disc, inspect it to find where all of the cracks are.
Make sure the disc is free of dust and debris. Wipe the disc in strokes, not in circular motions, with the cloth.
Apply a bit of toothpaste to a cotton swab. Gently rub the toothpaste on the crack in circular motions. You are essentially buffing out the crack with the toothpaste. You might see little scratches forming, but if the deeper crack is becoming less prominent, then you are doing it correctly. Do not apply too much pressure, as you might break the disc.
When you have diminished the size of the crack, dip a clean cloth into a bit of water and gently wash off the toothpaste. Dry the disc off.
Test the disc by putting it into your computer or game console. If you are having the same issue, try the toothpaste method again.
Use a gritty toothpaste, not a gel toothpaste, to buff out cracks.
