This will provide you with a cleaning cd that you can insert into your computer and it will clean the lens.
Please note that a cleaning process may be required if you use "dusty or scratched" CD media in your CD ROM. Always keep your disks media covered in a protective box/cover.

When doing this with a clean cotton cloth or shirt, wipe against the tracks, starting from the middle of the CD and wiping towards the outer side of the CD.

FLOPPY DRIVE CLEANING
If the disk drive head becomes dirty, "data errors" may occur. Accumulated dirt can scratch the disk. Regular cleaning is important to avoid dirt buildup.
To clean the disk drive head, use a commercially available fluid-type cleaning disk for dual-sided drives.
(1) Moisten the cleaning disk with cleaning fluid.
(2) Immediately insert the cleaning disk into the disk drive and execute a read operation. (Any type of load operation is ok.) An error message will appear.
(3) After approximately 10 seconds, press the eject button, and remove the cleaning disk.
(4) For approximately 5 minutes, do not use the disk drive.
(Using the disk drive before the cleaning liquid has dried may cause malfunctions.)
