- Fully functional wiper blades are essential for road safety, but they tend to be neglected. In the space of half a year, the wiper rubber covers an average distance of 800 km over the windscreen. Normal wear and tear is therefore unpreventable. The rear window wiper is generally used less frequently and is subject to a lower level of wear
- Environmental factors such as sunlight or ozone can also damage the wiper rubber: The rubber becomes porous, cracked and hard. Even frozen dirt residue on the windscreen can cause damage
- If your wiper blades leave a hazy film or streaks on the windscreen, or if they start to squeak or rub, the wiper blades may be worn and should be replaced as soon as possible
