There is a right way and wrong way to clean a CD or DVD. Let me first of all ask: How do you clean your CD or DVD? I am quite shocked at some of the answers that I am hearing. It is very important to clean your discs the correct way or else you will drastically reduce their lifespan. Cleaning them the wrong way can also render them useless after you clean them. So, to save you the heartache of losing any more CD’s or DVD’s, let me tell you the correct way to clean them.
It is actually quite easy. All you need to do is use a lint-free soft piece of cloth, slightly damped if the disc has dirt on it that is hard to remove using a dry cloth. Then use the cloth to wipe the face of the disc, doing so in straight line motions, i.e. wiping from the center of the disc to the edge. DO NOT WIPE IN CIRCULAR MOTIONS. THIS WILL DAMAGE THE DISC. See how simple that was? Just remember to wipe from the center to the edge until the entire surface has been cleaned. This way, your disc will still work after cleaning and it will last longer.
You may wonder why you should not wipe in circular motions. Well, the answer is simple: When something is burned onto the disc, the laser does so in circular motions. Remember that the CD or DVD spins in circular motions when it is being burned or played. Wiping the disc in circular motions damages the tracks on the disc, making it unusable after a while. So, remember to always wipe the disc from the center to the edge until it is totally clean.
