The first warning sign that lets you know that your windshield wiper blades need replacing is that screech that you here when the wipers are turned on in the rain when the window is clean and free of dirt. A new wiper will glide along the surface and make no noise except the bump sound at each cycle end. As you watch the wiper that is making the screech, you sometimes see tiny strips of rubber coming loose from the blade.
If the blade appears to be whole, you might be able to extend the life of the blade with a chemical found in auto stores like rain-x or some similar brand. Regular applications of rain-x to the glass also helps extend the life of the windshield wiper blade. Try wiping your wipers clean by hand with a damp paper towel or cloth, they might only be dirty https://twitter.com/Wiperadvisor_. Anytime that the blade starts to separate or have lit bits of rubber flapping is a good time to replace the blades. Many times, drivers will ignore the warning signs of a disintegrating blade refill until the wiper gets bent and has to be replaced with a complete wiper blade. Also, if your wiper blades tend to streak the windshield when there is plenty of water or make skipping sounds as they go back and forth, then blade replacement is probably the solution. If you need to stick your head out the window to see in rain, that is a good sign to replace the blades. If you inspect these wiper arms by propping it out as if you are replacing the blade and see rubber bits that are beginning to fray or find rips or cracks, then replace the blade.
