Inside windows
Use Ultra-Clear Spray Glass Cleaner (E4AZ-19C507–AA) for the inside
windows if they become fogged.
Cleaning mirrors
Do not clean your mirrors with a dry cloth or abrasive materials. Use a
soft cloth and mild detergent and water. Be careful when removing ice
from outside mirrors because you may damage the reflective surface.
