07 12.25 The restoring time depends on the dirt quantity and dirt types. If the mirror is exposed to the sunlight 1 or 2 days, the rain clearing effect will be restored. For the fast recovery of the rain clearing effect, rinse the mirror thoroughly after cleaning it with neutral detergent (which does not contain silicon and abrasive). (Some car shampoo or glass cleaner contains silicon or abrasive, read the contents carefully.) z Do not use any water repellents as they can destroy the rain clearing effect. If any repellent gets stuck on the surface of the mirrors, wash it off with neutral detergent, then rinse thoroughly. NOTICE To maintain the rain clearing ability, and prevent the mirrors from being scratched, observe the following precautions. z Do not use any glass cleaners that contain compounds. z If ice should jam the mirror, do not scrape the mirror. Use a spray de− icer to free the mirror. z Wash off any wax stuck to the mirrors with neutral detergent and rinse thoroughly as any wax on the surface of the mirrors can cause the rain clearing effect to be lost. 420
