«CD CLEANING : Dirty CDs can cause read errors and/or cause CDs to not work at all.
Procedure: Cleaning CDs should be done with a CD cleaning kit but can also be done with a normal clean cotton cloth or shirt. 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. Never wipe with the tracks; doing so may put more scratches on the CD.
It is recommended when cleaning a CD that water is used. However, if the substance on a CD cannot be removed using water, pure alcohol can also be used.»
