The windscreen wipers do not wipe clean? What can be the reason for this?

The question addresses the importance of ensuring that your vehicle's windscreen wipers function effectively. The windscreen wiper blades can wear out over time, which means they may not make proper contact with the windscreen, leading to poor visibility. Additionally, an oil film on the windscreen can prevent the wipers from cleaning effectively, creating a dangerous driving situation due to inadequate visibility during rain or wet conditions.

According to German traffic regulations, vehicles must be maintained properly to ensure safe operation. This includes ensuring that all essential components, such as the windscreen wipers, are functioning correctly. Failing to address these issues can result in fines or penalties if stopped by the police, as well as increased risk of accidents. Therefore, it is crucial to consider all potential causes when troubleshooting, which is why the combination of both options regarding blade condition and oil film is necessary to ensure thorough understanding and maintenance of vehicle safety.
