If you suffer from a scratched CD or DVD, here's a tip to fix it and stop the skipping!
Get some Crest Kids' Toothpaste -- yes, it has to be the kids' kind, regular adult toothpaste doesn't work. Squirt four pea-sized dots of toothpaste onto the CD or DVD. Spread the toothpaste around gently with your fingers. Keep rubbing until the toothpaste starts to dry out and becomes hard to spread around. Rinse with warm water until all the toothpaste is gone, and then buff with a soft, dry cloth. No more scratches!
