WINDSHIELD WIPER BLADES
It's generally recommended that you swap out your old wiper blades for new ones every six months. Because they are made from rubber, a material that deteriorates over time as they age, they start to break down.
Worn out wiper blades can limit visibility and can struggle to keep your windshield spotless and streak-free. Because windshield visibility is critical to your safety on the road, it's important to have blades that are functioning as they should.
To ensure the quality of your wiper blades, regularly inspect the condition of the rubber. Make sure there are no cracks or splinters or erosion. Test how well the blades remove washer fluid from the window. If they spread it instead of cleaning it off, it's probably time to replace them.
