Cleaning windows and exterior mirrors
Moisten the windows and exterior mirrors with commercially available, alcohol-based glass cleaner.
Dry the glass surfaces with a clean chamois leather or a lint-free cloth. Chamois leathers which have been used on painted surfaces are not suitable for use on glass surfaces. They will be soiled with wax deposits which could smear the surfaces.
Use window cleaner or a silicone remover to clean off rubber, oil, grease and silicone deposits .
Removing wax
Car washes and care products could leave wax deposits on the glass surfaces. Wax residue can only be removed using a special cleaning product or cleaning cloths. Wax deposits on the windscreen could cause the wiper blades to rub. Volkswagen recommends that you use a cleaning cloth to remove wax deposits from the windscreen each time the vehicle is cleaned.
A window cleaner specifically for removing wax will stop the blades rubbing if added to the windscreen wash water. Dilute the cleaner as instructed. Grease removing cleaners will not remove wax deposits .
Special cleaners and glass cleaners are available from Volkswagen dealerships. Volkswagen recommends the following cleaning agents for removing wax deposits:
Removing snow
Use a small brush to remove snow from the windows and exterior mirrors.
Removing ice
The best method to remove ice is to use a de-icer spray. If you use an ice scraper, do not move it to and fro, but push it in one direction only. Dirt could scratch the window when moving the ice scraper back.
