There are many simple ways to care for your windows. One of the simplest ways is to clean them occasionally, with a soft cloth. Use a mild soap to clean the exterior of the window and avoid acidic or abrasive cleaners. If you do have to clean them, always test on an inconspicuous area first to make sure the cleaning product does not damage the finish. Another simple way to care for your windows is to apply a layer of dust-removal wax or grease on the exterior.
