If you're like most people, you don't think about your wiper blades until they start to streak or make noise. But if you take a little time to clean and maintain them, your wiper blades will last longer and do a better job of keeping your windshield clear.
The first step is to remove any dirt, debris or snow from the blade. A soft cloth can usually do the trick, but if the blade is really dirty, you may need to use a brush or even a hose to get it clean. Be careful not to bend or damage the blade while you're cleaning it.
Next, check for cracks or splits in the rubber. If you see any, it's time to replace the blade. Most hardware stores and auto parts stores sell replacement wiper blades, so finding one shouldn't be too difficult. Just be sure to get the right size for your vehicle.
Once you have a new blade (or two), it's time to install it. First, lift up on the arm that holds the wiper blade so that it's at a 90-degree angle from the windshield. Then slide the new blade onto the arm and lower it back into place. Make sure that it's securely attached before moving on to the next one.
