How to lubricate windshield wipers?

As a supplier in the auto parts industry, I often receive questions about maintaining windshield wipers. It’s a simple yet crucial aspect of vehicle upkeep, and knowing the right way to lubricate can help avoid costly repairs and replacements. Let me walk you through the best practices and products for keeping your windshield wipers in top condition.

Lubricating windshield wipers correctly ensures smooth operation, reduces wear and tear on wiper blades, and improves visibility while driving. Regular maintenance can save you money on replacements and keep your customers happy.

Taking care of wiper blades is not just about applying any lubricant. The right products and proper techniques make all the difference in performance and longevity. Here’s everything you need to know to keep those wipers working as they should.

What can I use to lubricate windshield wipers?

I’ve worked with many clients who ask about the best lubricants for wiper blades. It’s important to use a lubricant that maintains flexibility without causing damage to the rubber.

For windshield wipers, I recommend using silicone-based sprays or rubber lubricants. These lubricants prevent the rubber from stiffening, keeping it pliable for longer and extending the lifespan of the wiper blades.

Why silicone-based sprays are the best choice

Silicone lubricants are designed to protect the rubber components of wiper blades. Unlike petroleum-based lubricants, silicone doesn’t break down the rubber over time. It helps the blades maintain their flexibility, reducing the chances of cracks or stiffness.

I also advise clients to avoid using oil-based lubricants¹. They can leave a greasy residue that attracts dirt and grime, which can ultimately cause the wipers to wear out faster. Silicone-based lubricants provide a non-oily, dry finish, which helps keep the blades clean and efficient.

The importance of regular application

When wipers² glide smoothly, drivers get clearer visibility, which directly impacts safety. Applying the lubricant regularly ensures that the blades stay in good condition, even during extreme weather conditions.

Should you put WD40 on your windshield wipers?

WD40 is a common go-to lubricant for many tasks, but it’s not always suitable for windshield wipers.

I don’t recommend using WD40 on windshield wipers. While it’s great for general lubrication, it can break down rubber over time and cause premature wear. Instead, opt for a silicone-based lubricant or rubber protectant.

What makes WD40 unsuitable

WD40 is a solvent, not a lubricant, and it works by dissolving grime and dirt. While it may temporarily clean the blades, it doesn’t offer long-term protection for rubber. Over time, it can cause the rubber to dry out and crack, leading to noisy, inefficient wipers.

For the best results, stick to silicone-based products³ that are specifically designed for rubber components. They will maintain the integrity of the wiper blades and provide a longer-lasting solution for smooth operation.

My recommendation

I tell my clients to avoid WD40 for automotive parts maintenance, especially on wiper blades. It’s a quick fix that doesn’t offer the longevity that a silicone-based lubricant does. Regular use of a dedicated wiper lubricant⁴ will not only improve the performance of the blades but also reduce the frequency of replacements.

How do I make my wipers glide smoothly?

Smooth wiper operation is essential for clear visibility, especially during rainstorms. A common problem is wipers that leave streaks or make noise while operating. The solution lies in both cleaning and lubrication.

To make your wipers glide smoothly, start by cleaning the blades thoroughly before applying any lubricant. Dirt, grime, and grease can cause the blades to drag, wear down the wiper linkage, and result in streaks.

Clean before lubricating

I always tell my clients that cleaning the wiper blades⁵ before lubricating them is essential. Dirt and grease can build up on the rubber and affect the blade’s ability to wipe the windshield effectively. When you clean the blades, use a mild cleaner and a microfiber cloth. Once clean, dry the blades completely before applying the lubricant.

The right lubrication technique

After cleaning, apply a light coat of silicone-based lubricant⁶ to the rubber blade. Make sure to distribute the lubricant evenly across the blade for optimal coverage. A smooth application will allow the blades to glide effortlessly across the windshield without causing streaks or noise.

When done properly, this simple maintenance task will ensure smooth, quiet wiper operation for months to come.

How to fix noisy wiper blades?

Noisy wiper blades are often a sign of friction between the rubber and the windshield. This can be caused by dirt, damage, or dry rubber. Fortunately, there are steps you can take to silence those squeaky wipers.

To fix noisy wiper blades, clean the blades thoroughly and lubricate them with silicone-based spray. If the squeaking persists, check for wear or damage, as this may require replacing the blades.

Identifying the cause of the noise

The most common causes of wiper blade noise are dirt, dried-out rubber, or worn-out blades. I once worked with a fleet client who complained about squeaky wipers that wore out too quickly. The issue was simple: they hadn’t been lubricating the blades regularly. After I recommended using silicone-based lubrication⁷, the squeaks stopped, and the blades lasted longer.

The importance of regular maintenance⁸

I encourage clients to maintain their wipers by cleaning and lubricating them every few months. This helps prevent squeaks and extends the life of the blades. Neglecting this step can lead to more significant issues, like skipping or streaking, which are both frustrating for drivers and costly to fix.

If you notice that the wipers are still noisy after lubrication, it may be time to replace them. Worn-out blades cannot be fixed with lubrication alone and may need to be replaced to restore smooth, quiet operation.

Conclusion

Maintaining windshield wipers⁹ is crucial for safe driving, especially in bad weather. By using the right silicone-based lubricants, cleaning the blades regularly, and performing simple checks, you can ensure the wipers glide smoothly and quietly for a longer time. These steps can save you money on replacements and improve customer satisfaction. Taking care of wiper blades isn’t just about avoiding noise; it’s about providing clear, safe visibility on the road.
