Replace damaged components if necessary

Important note: Do not use plain water or dishwashing liquid as a substitute for specialized glass cleaner. According to an AutoZone survey, 95% of auto experts recommend only using specialized glass cleaner to protect the sprinkler system and windshield.

Wiper maintenance is an important part of maintaining safe driving. According to NHTSA statistics, regularly replacing wiper blades and using the correct type of windshield washer fluid can reduce the risk of accidents related to poor visibility in bad weather conditions by up to 15%.

Remember to check and maintain your wipers at least twice a year to ensure they always operate effectively, especially before the rainy season or when the weather changes suddenly.

Frequently asked questions (FAQ)

1. How often should car wipers be replaced?

According to manufacturers' recommendations, wipers should be replaced every 6-12 months of use. However, replacement frequency may vary depending on usage and environmental conditions. Research by the American Automobile Association (AAA) shows that 90% of drivers only replace windshield wipers when they are completely broken, which reduces the effectiveness of glass cleaning by 31% and increases the risk of accidents in the car by 22%. bad weather conditions.

2. Should we use silicone wipers instead of traditional rubber?

Silicone wipers have many advantages compared to traditional rubber types:

• Life expectancy is 2-3 times higher (average 18-24 months compared to 6-12 months)
• Better heat resistance, suitable for hot climates
• Leaves less water stains

However, the price is 30-50% higher than rubber. According to a survey by Consumer Reports, 78% of silicone wiper users are satisfied with their performance, compared to 62% of traditional rubber wipers.

3. How to preserve windshield wipers in winter?

To preserve wipers in winter, you should:

• Raise wipers off the windshield when parking overnight to prevent freezing
• Use specialized anti-freeze for glass cleaner
• Clean windshield and wipers before use
• Consider using specialized winter wipers

According to NHTSA statistics, applying the above preservation measures can reduce the number of accidents related to poor visibility in cold weather conditions by up to 40%.

4. Is there any way to increase the lifespan of wipers?

To increase the lifespan of your wipers, you can:

• Clean wipers periodically (every 2 weeks) with 70% isopropyl alcohol
• Avoid using wipers on dry glass
• Cover the car indoors or use a cover when parking outdoors
• Change the wiper angle when not in use to reduce pressure on one point

Applying these measures can extend wiper life by 20-30% according to research by the German Institute of Automotive Technology (IAT).

5. How to fix the problem of wipers leaving water streaks on the glass?

To fix the problem of wipers leaving water streaks:

• Clean the windshield with a specialized degreasing solution
• Clean wiper blade with 70% isopropyl alcohol
• Check and adjust lever pressure (if any)
• Replace the wiper blade with a new one if the above measures are not effective.

According to a study by the University of Michigan, 85% of wiper streaks can be fixed with the above measures without needing to be replaced.

6. How to adjust the spray direction of the glass washer nozzle?

To adjust spray direction:

• Mark the current location of the nozzle
• Use a small needle or pin to adjust the angle of the spray hole
• Check the new spray direction and readjust if necessary

Note: The nozzle should be directed toward the upper 1/3 of the windshield for optimal effectiveness. According to Bosch research, adjusting the spray direction correctly can increase glass cleaning efficiency by 25%.

7. Is it necessary to use anti-freeze glass cleaner?

The use of anti-freeze glass cleaner is necessary in areas with temperatures below 0°C. This type of water can:

• Anti-freeze at temperatures as low as -30°C
• Cleans glass more effectively in cold conditions
• Protects sprinkler systems from damage due to freezing

According to NHTSA statistics, using anti-freeze glass cleaner reduces the number of accidents related to poor visibility in winter by 18%.

8. How to fix squeaky windshield wipers?

To fix the problem of screeching wipers:

• Clean the windshield and wiper blades
