If you have a car with rubber windows, there are a few things you can do to help keep them clean and looking new. First, use a mild soap solution to clean the windows. This will remove any dirt and debris that may have built up on the glass over time. Second, use a dry cloth to wipe down the windows. This will remove any fingerprints or other markings that may have been left behind on the glass. Finally, use a vacuum cleaner to clean the entire window area. This will remove all of the dirt and debris that has built up over time.
