Replacement advice
How often should a wiper blade be replaced?
As a rule windscreen wiper blades should be replaced at least once per year.

Why replace?
Wiper blades eventually deteriorate with use, producing a streaky or uneven finish on the windscreen. To ensure a clear, safe field of vision even in bad weather, it is important to ensure the wiper blades are regularly checked and replaced as soon as deterioration is seen.

Replacement Signs
These are the four main signs of wiper blade deterioration that are visible on the windscreen glass. These symptoms will help you determine when a wiper blade needs changing.

Symptom: Narrow streaks are left on the windshield.
Cause: Foreign matter has attached itself to the rubber blade, or the edge of the blade is worn.
Remedy: First, clean the edge of the blade. If streaks still appear, replace the wiper blade.

Symptom: Wiper blade jumps and makes a lot of noise.
Cause: The wiper blade does not move smoothly across the windshield, but vibrates noisily and bounces.
Remedy: First, clean the windshield; then check the angle. If jumping persists, replace the wiper blade.

Cause: Rubber deformation
