Driving in the rain is annoying enough. When you add the repetitive squeak or chatter of the windscreen wiper, it can be downright unnerving. Not only are you trapped inside the car in the pouring rain, you are forced to tolerate the loud reminder that you haven't been taking care of your wiper blades. The noise you hear is your wiper blades' way of crying for help. Fortunately, there are ways to quell the squeak and chatter and return your wiper blades to normal.
Examine the wiper blades for signs of wear or drying. Windscreen wiper blades should be replaced every six to 12 months to keep them in top shape. Worn blades not only cause squeaking and chattering, they pose a hazard to your safety if they fail to clear away water properly.
Replace worn blades. Wiper blades should always be replaced in pairs, even if only one blade shows wear or has become brittle. If blades appear to be in good condition, wipe them down with a soft cloth moistened with water to remove any dirt or debris that might cause the squeaking.
Wash the windscreen with a solution designed for windscreens. Using other products can deteriorate the wiper blades, causing more damage. Use a soft scrubbing brush if necessary to remove insects, wax or other residue.
Check your wiper blades regularly to prevent future problems. Blades on vehicles that have been sitting in areas with infrequent rain can become too dry and require replacement.
