Why change your wiper blades?
Many road traffic accidents are related to poor visibility, with defective wiper blades a common cause. In addition, having ineffective wiper blades can cause your vehicle to fail an MOT inspection.
When wiper blades become rough with an uneven surface, they begin to spread accumulated dust and dirt on the windscreen. This extra soiling can reduce visibility further. If wiper blades are very badly deteriorated, they can even scratch the windscreen.
