It's a good idea to change your windshield wiper blades once a year at least; twice a year, if you're in a rainy climate. Most experts recommend replacing the whole blade and not just the inserts. Here are some quick tips on how to replace your windshield wiper blades:

• Look online for an instructional video by searching the title of this article.
• Look in your vehicle's owner's manual for instructions on finding the right blades for your make and model. Determine whether you need a special blade depending on the season or other circumstances.
• Clean your windshield washer jets (you'll find them just below the front windshield, or just above the rear windshield) with a toothbrush, a fine needle, or an old guitar string, and fill up the fluid reservoir.
• Several different types of washing fluid is available. Consider whether you want an anti-bug formula, de-icing formula, or the basic all-weather variety.
• The package of new blades might contain several types of attachments. Choose the one that matches the attachment on your existing blade.
• Gently pull the windshield wiper arm away from the car. It should pivot so that it sticks out straight.
• Remove the blade from the arm. You may have to use a screwdriver or other object to release a tab.
• Replace the old blade with the new one, just reversing the manner in which you took the old one off, and pivoting the arm back into place.
• Test the new blades by letting them wash your windows.
