How to Clean a Laser Lens

A dirty laser lens in an optical drive or device can cause skipping audio and video, and even cause the device to fail to read the disc. Even on devices where the electronics are inside, dust can enter and settle on the lens. If you are experiencing issues caused by a dirty lens, you can clean the disc with items you probably already have around your home. If you can't access the laser lens, kits are available to clean the lens for you.
