For 1990-2009 cars

The radio front face and buttons along with the CD changer front face and sides will look their best if they are cleaned properly from time to time. Use a water-damped cloth with a mile soap to remove dirt. Do not use any harsh cleaners or chemicals as they may cause irreversible damage.

Cleaning the radio or CD player internally is not recommended. The CD lens is very sensitive to scratches. If one small abrasive particle is accidentally brushed across the lens, the radio or CD changer will no longer operate.
