Notes When Repairing and Maintaining Car Wipers

Wiper is an important part of the car, helping to clean the windshield, ensuring clear vision for the driver in bad weather conditions such as rain, snow, fog. Choosing and using the wiper properly will help increase safety when driving.

However, under the influence of time and environmental factors, the wiper cannot avoid deterioration. So, when repairing and maintaining the wiper, what should we pay attention to? Let's delve into this issue.

Causes of wiper failure

1. Aging over time

Wear: The rubber wiper blade is in direct contact with the windshield, subject to constant friction, resulting in wear and reduced wiper efficiency.

Effects of UV rays: Ultraviolet rays from sunlight cause rubber to age, become hard and brittle, and easily crack. A study by Stanford University shows that UV rays can reduce the life of rubber by up to 50%.

Oxidation: Exposure to oxygen in the air also contributes to rubber aging.

2. Lack of regular maintenance

Dirt: Dirt, sand, tree sap, etc. stick to the wiper blade and windshield, creating an abrasive film that scratches the glass and reduces wiper efficiency.

Substandard windshield washer fluid: Some windshield washer fluids contain strong chemicals that can damage rubber wiper blades.

3. Environmental impact

High temperature: High temperature in summer causes rubber to age and deform quickly.

Acid rain: Acid rain can corrode wiper blades and metal parts of the wiper arm.

Signs of damaged wipers

5 main warning signs of damaged wipers:

• Leaving water streaks: After wiping, the glass still has many water streaks, obstructing visibility.
• Squeaking: An unpleasant screeching sound caused by friction between the wiper blade and the windshield.
• Shaking: The wiper shakes violently when operating, possibly due to a weak spring or warped wiper blade.
• Fogging: A thin layer of fog appears on the glass after wiping, usually due to uneven wear of the wiper blade.
• Cracks, breaks: Cracks, breaks in the wiper blade or wiper arm.

• Park in the shade: Avoid parking in direct sunlight for long periods of time, as high temperatures can damage the wiper blades.
