Windshield wipers are perhaps one of the most overlooked components on your Porsche. Nonetheless, if you’ve ever been surprised by a rainstorm while driving, then you know that you depend on them to improve your visibility to safely get to your destination. In addition, old, sun-stricken, cracked or otherwise damaged wiper blades do not work adequately and may scratch your glass leaving permanent damage to your windshield. Every month remove any dust or dirt by wiping the blade with a wet towel, and inspect for any worn, rigid, or peeling areas. If you hear screeching when you operate your wipers, then you may very well be scratching your windshield and need to replace them. Check your wiper blades at least prior to the rainy season and replace them when necessary to ensure that you always have a clear view of the road. A good rule of thumb is to replace your wiper blades every 6 months. Replacing your blades is one of the easiest and most affordable ways that you can improve the safety of your vehicle.
