How to Stop Squeaking Windscreen Wipers

Small but mighty, our windscreen wiper blades are some of the most overlooked parts of our cars. They keep our vision clear on rainy days and remove dust and debris on our windscreen, providing us with a safe and comfortable driving experience for drivers and passengers. If you have a newfound appreciation for your windscreen wiper blades, keep that going! However, apart from those reasons to notice your windscreen wipers, you will definitely notice them when they start to squeak. That dreaded squeak will soon be resolved once you finish this article, we guarantee. 

What causes windshield wipers to squeak?

Most would think squeaky windshield wipers stem from their bolts or clasps when it usually comes from having dirty windshields. With dirt and grime as minute as dust particles, once they accumulate, they can cause unwanted friction that leads to squeaking. Apart from this, here are some other problems as to why you might have squeaky noises coming from your windshield wipers: 

  • Failing wipers
  • Dirty wipers 
  • Dry wiping 
  • Wrong wiper model 
  • Wipers not adjusted properly 
  • Damaged or old wipers

Why is it bad? 

For one, squeaky windshield wipers get annoying over time. A squeak or two may be bearable, but once it gets constant, that is where the frustration kicks in. Next, this seemingly mundane squeaking noise can be a symptom of a much bigger problem such as failing wipers. We all know that our windscreen wipers, although small, are mighty in aiding us whenever we drive. Hence, it is pertinent that you examine those squeaky wipers. In fact, any unnatural noise coming from your vehicle should be checked to avoid future problems. 

How do you stop windshield wipers from squeaking?

There are several ways to prevent and stop your windshield wipers from squeaking and anyone is more than capable to solve them on their own with just these 8 simple ways. 

  1. Make sure both your car wipers and windshield are clean

You have probably seen and heard this multiple times so take this as a humble reminder from us to you to clean regularly and maintain your wipers and windshield. Naturally, your wiper hinges and screen get caked with dirt, grime and all sorts of things as you drive. Take the time to properly rinse and wipe these parts. 

  1. Check your windshield wiper fluid 

This refers to the fluid coming out of your wipers to clean the windshield while you are on the road. If the wiper fluid is too low, this can cause your windshield to be too dry for a smooth wipe which causes those disliked squeaky noises. Make sure to always have enough windshield wiper fluid as this could also cause ineffective windshield cleaning.

  1. Your wiper blades might be in a need of replacements 

Your squeaking blades could just simply mean it is time for a change or replacements. Old blades will wear off and lose their ability over time which can damage your windshield instead. We advise you to get them replaced every six months or annually to ensure a safe and squeak-free driving experience. 

  1. Tighten the fasteners on your wiper blades 

Like all bolts and screws, they can get loose. Just like the fasteners on your wiper blades, they get loose as time goes by. Do not over-tighten them nor loosen them too much as either extremity will produce squeaking noises. Instead, experiment to find the right amount of tightness for the blades to work optimally. 

  1. Windshield replacement 

Sometimes it is not entirely the windshield wipers’ fault but rather the windshield. After years of constant exposure to the environment, your windshield will tend to have a rougher surface than it initially started. You can fix this by regularly cleaning your windshield with soap and water. However, if this persists, you might want to consider replacing a new windshield altogether. 

  1. Position your wiper blades accordingly 

If you have taken your wiper blades out to clean them, great job! Now putting them back may be the tricky part that causes the problem of squeaking noises. Some blades need to be placed back in particular positions for them to work effectively. You just need to adjust them and test them accordingly. Remember, your windscreen wipers should not be vertical when in use.  

  1. Check on the rubber of your wipers

Like our skin, constant exposure to the sun can get damaging. The same goes for the rubber in your wipers. They get hardened and stiff due to sun exposure and many other factors. By using a little bit of rubbing alcohol, wipe the rubbers and they should soften right up. 

  1. Replace your wiper blade assembly 

Last but not least, you may want to check your wiper blades assembly as over time they can get worn off from use. This is an easy fix as all you need to do is to remove the nut holding the assembly in place and install a new assembly altogether. 

Try out these methods to alleviate the noise. However, if they do not work, do bring your car to the mechanic and get a thorough check for any possible hidden problems your car may have. 

How do you lubricate windshield wipers?

To lubricate your windshield wipers, all you will need is soap, water and some silicone lubricant. 

  1. Firstly, wipe your windscreen wiper blades down and clean them with soap and water. 
  2. Dry them for at least 15 to 20 minutes. 
  3. Now, spray them with some silicone lubricant.

Can you use WD-40 on wiper blades?

Yes, you can. 

Spray some WD-40 on your wiper blades and wipe them clean using a rag. 

What can happen if you don’t repair them?

What began possibly as a harmless squeaking windscreen wiper noise will turn into forms of unwanted, permanent scratches on your windshield. Sure, they may start out invisible and small but once they become visible, it will be too late. You would have to replace an entirely new windshield. Instead, opt to prevent these extra costs and emotional damage to you (and your car) by regularly checking and maintaining your vehicle’s health.
