If your DVD player, video game console or CD player is skipping or freezing up, try cleaning your laser lens. The laser lens is responsible for reading the data from the disc. If it is dirty, it may not be able to properly read your disc. Although you can buy discs to go into your disc players that will clean the laser disc, alcohol can be used for quickly and effectively cleaning laser lenses.
Disassemble the disc player, if necessary, to expose the laser lens. Specific instructions for doing this can be found with your owner's manual. Instructions will vary among types of disc players.
Locate the laser lens. It will be glass and usually located under the disc clamp. Some laser lenses have a blue tint to them. If you are finding it difficult to locate the lens, shine a flashlight into the area and watch for the part that gives off a reflection.

Moisten a cotton ball with rubbing alcohol. Rub the cotton ball over the laser lens gently for about 30 seconds to remove any dust and dirt. Go over the lens with a dry cotton ball to remove any moisture.
