How Do I Know If My Wiper Blades Need Replacing?

When should you replace wiper blades? If you notice these symptoms, it might be time. However, you could also learn how to clean wiper blades, which might extend the life. What is the best thing to clean wiper blades with? We recommend using a clean rag with warm soapy water.

  • Windshield Looks Streaky 
    The windshield wipers are meant to improve visibility, not make it worse. When they stop performing their job, it’s possible to get streaks across the windshield that inhibit your viewing area. If you clean them off and it doesn’t help, put on a new pair.
  • Roughed-Up Rubber 
    The rubber on the windshield wiper should be smooth, free of cracks, splits, or breaks. If there are imperfections in the rubber, they aren't going to work as they should. These old wipers will need to go to make room for a replacement.
  • Screechy/Squeaking Chattering Sound 
    When the wipers begin to drag across the glass, you are left dealing with a terrible noise that can quickly ruin your drive. Not only will the sound drive you insane, but your windshield isn’t getting cleaned properly. If you can’t clean off the debris, it’s time to change the wipers.
  • Wet Spots 
    Over time, the wipers can become deformed, leaving wet spots on your windshield. Often this happens if you use the wipers to remove snow or ice. If there is physical damage to the wiper itself, you will need to replace that with the blades.
  • Metal Corrosion 
    If your wipers are old, the metal that holds the blade in place might start to corrode. As with all car parts, these metal pieces are subject to lots of weather changes and air pollution. Over time, they will start to wear out, requiring a replacement.

How Often Should You Change Your Wiper Blades?

To figure out how often to change windshield wiper blades, you must first answer – how long do wiper blades last? Figuring out how often to replace wiper blades will require you to look at a few factors. However, most people recommend following a six-month replacement schedule.

Every six months, the wipers should be changed unless you notice problems sooner. Thankfully, it’s easy to replace windshield wipers yourself, no matter what type they are, whether they are traditional or hybrid models.

Factors That Affect The Longevity

  • Usage 
    If you live in Seattle, you are using your wiper blades more than someone in Arizona. Over time, the glass of the windshield will start to break down the blades, especially if you are using them more frequently.
  • Environment 
    However, even regions that don’t see a lot of rain can cause more abuse to the wipers. In the desert, the constant heat can create problems with the rubber material. The lack of moisture eventually leads to cracking and breakage.
  • Brand/Quality 
    It’s also important to consider what brand of wiper blade you choose. If you buy cheap windshield wipers, they are going to wear down faster, just like cheap brake pads do. If you spend a little more, you can count on better visibility for longer periods of time.

What Happens If You Don’t Change Your Wiper Blades?

If you don’t change your wiper blades when it’s required, you face a lot of risk on the road. If you accidentally get caught in a downpour without properly working blades, you won’t be able to see where you are going. Furthermore, broken blades could leave the bare metal exposed, which could cause damage to the windshield.

Tips For Extending The Life Of Wiper Blades

If you want your wiper blades to last longer, follow these tips.

  • Always use the blades with proper lubrication. If it isn’t raining, make sure you spray the area with windshield wiper fluid.
  • If you need to remove stuck-on items, use a squeegee instead.
  • Don’t use your wiper blades to remove ice or snow.
  • Check the wiper blades often and clean them off regularly.
  • Know what kind of blades you have. If you are asking, “what is a beam wiper blade” or “what kind of wiper blades do I need,” it’s best to read your owner’s manual for more information.
