Annually, the local Dulles airport area can expect about 2 to 5 inches of rain annually in October and November. However last year we experienced almost 8 inches of rainfall in October and only 3 in November. Because the start of the cold season can be so unpredictable when it comes to precipitation, it is important to choose the right wiper blades for your vehicle and maintain them properly.

          A good reminder to change your wiper blades is at the beginning of the spring and fall seasons. The lifespan of your blades will depend on the quality; as cheaper blades may not last as long as more expensive blades. Kenny recommends higher quality blades such as Rain-X brand, which typically cost as much as $24.00. From his personal experience, these blades can last up to a year or a year and a half. While he recommends Rain-X as an across-the-board reliable brand, he does advise that because of the unique curve and incline specific to every car’s windshield, a single type or brand of wiper blade might not fit perfectly to all cars.
