Protecting Your Car's Wipers During Car Wash

Car washes are a regular part of maintaining your vehicle's exterior. However, the process can be tough on your car's wipers, especially if you aren't taking the necessary precautions. Understanding the potential damages and how to protect your wipers can extend their lifespan and keep your car's visibility clear. Let's dive into some key points to help you protect your window wiper arms and blades during car washes.

The Importance of Removing Wiper Arms and Blades Before Car Wash

Before you do a car wash, it is a good idea to take your window wiper arms and blades off, especially if you care about the longevity and effectiveness of your wipers.

The Pressure on the Wiper Arm and Glass Surface:

The wiper blade primarily relies on the pressure provided by the spring to the windshield. Over time, this spring will deflate, reducing the pressure on the glass surface. This decrease can lead to ineffective operation, as the blade may not make full contact with the glass, leading to streaking or incomplete wipe. When the pressure is insufficient, it is time to replace the wiper blade.

Wiper Arm Deficiencies:

Moreover, the wiper arm itself is under significant strain. The impact of the water spray and the force of the wipers scraping against the glass can cause the arm to bend or break. Should the arm break, the entire wiper system will cease to function effectively. Inspecting and replacing the arm before the car wash can help prevent this issue.

Friction and Wiper Rod Bushing:

The wiper connecting rod bushing is another critical component that can wear out over time. Pressure and friction can cause wear and tear, which might result in the bushing wearing down or even falling off. This can lead to abnormal noises and affect the wiper's performance. Inspecting and replacing the bushing during a car wash can avoid these complications.

Abnormal Noise from the Wiper Motor:

Lastly, if you notice abnormal noises coming from the wiper motor, it is a sign that the motor might need replacement. This requires professional inspection and maintenance to ensure the wipers continue to function properly.

Exceptions: Rear Wiper Protection

One piece of good news is that you generally only need to worry about the rear wiper during a cloth wash car wash. Modern car washes often include plastic sleeves designed to cover and protect the rear wiper. These sleeves can reduce the chance of damage and ensure the wiper remains in good condition.

Consult your dealer or mechanic if you need to learn more about how to safely remove and reattach the rear wiper. Some rear wipers can be easily detached by lifting the arm and sliding a little clip at the base of the mount. However, not all rear wipers require this step. Always ensure that the clip is secure when you return the wiper arm to its position.

Conclusion

Car washes don't have to be detrimental to your car's wipers. By taking the time to understand the potential risks and implementing the necessary precautions, you can protect your wipers and maintain clear visibility while driving. If in doubt, it's always best to consult a professional for advice on how to best care for your car's wipers during car washes.
