We always say that safety should be your top priority when on the road, so visibility and safety should never be neglected. One of the key components in ensuring good visibility while driving is having functional windshield wipers. These small but mighty tools play a crucial role in wiping away rain, snow, and debris from your windshield, allowing you to have a clear view of the road ahead.
How often should windshield wipers be replaced? It varies, depending on multiple factors, such as weather conditions, frequency of use, and overall wear and tear. Generally, these auto glass parts last 6-12 months, but we recommend you inspect them at least quarterly and replace them if necessary.
Let’s examine all the factors that can affect the lifespan of your wipers and how to know when it’s time for a replacement.
How Long Do Windshield Wipers Last?
The general lifespan of windshield wipers is 6-12 months. However, it varies, depending on a variety of factors such as:
1. Climate
The most impactful of all the factors affecting your wipers’ lifespan is your climate. Seasons and daily weather have a huge impact on how long your wipers will last.
For example, your wipers may wear out the fastest during winter months as they have to work harder to remove snow and ice from your windshield. In contrast, wipers may last longer in milder weather areas.
If you live in areas that rain way more often, your wipers will be working overtime and may wear out faster. Dry weather may be good, but not so much in windy and sandy areas.
Dust and sand particles can damage the wipers, shortening their lifespan.
2. Frequency of Use
Do you work at home and rarely use your car, or do you use it for work and still take road trips on weekends? A personal car won’t see as much use as a taxi or delivery vehicle, so the windshield wipers will last longer.
That doesn’t mean you shouldn’t regularly inspect the wipers if you’re not using them as often.
3. Quality of Wiper Blades
Many car owners who come to us for the first time ask us, “Why didn’t I need to change my wipers as much when I first bought this car?”
That tends to happen when your replacement parts aren’t as good as the original parts in your car. Most aftermarket wipers are cheaper than the original equipment manufacturer (OEM) options, and for good reason: you’ll keep buying and replacing them.
4. OEM vs. Aftermarket Wiper Blades
OEM options are designed specifically for your car model, come with a warranty, and often last longer than aftermarket wipers. While they may be more expensive upfront, they can save you money in the long run by lasting longer and requiring fewer replacements.
On the other hand, aftermarket wipers are mass-produced and may not fit your windshield perfectly. They don’t offer reassuring warranties, and their lifespans are much shorter.
5. Exposure to Dirt, Salt, and Debris
Do you work in rough areas, or do you like off-road adventures? If so, don’t be surprised if your windshield wipers wear out faster than expected. Constant exposure to dirt and debris can cause premature wear on your wiper blades.
Taking your car to the beach? The salty air can also cause corrosion on your wiper blades, leading to reduced performance and increased wear and tear.
Don’t abandon your hobbies or job. Instead, regularly clean your wipers and windshield to remove any dirt or debris. Invest in high-quality, durable wiper blades that can withstand harsh environments.
How Often Should Windshield Wipers Be Replaced?
You need to replace windshield wipers as often as is necessary for your safety. Generally, replace windshield wipers every 6-12 months, or every 6,000-10,000 miles. However, circumstances vary, so this recommendation applies to average driving habits in moderate conditions. If you drive often in harsh conditions, you may need to do it more often.
Follow Manufacturer Instructions
Every manufacturer has its own specific recommendations for when to replace windshield wipers, so it’s always best to check the owner’s manual. Manufacturers also often include a sticker on the windshield or in the package with the wiper blades with a suggested replacement date.
Regular Inspection Is Crucial
Don’t wait until your wipers start failing on the road. Regularly inspect your wiper blades for physical signs of deterioration, such as cracks, tears, or uneven edges.
Noticing issues early helps you to proactively deal with them before they grow into costly problems. Inspect your wipers at least quarterly or every time you get an oil change.
Signs It’s Time to Replace Your Windshield Wipers
1. Streaking or Smearing Water
The most obvious sign you need to replace your wiper blades is when they streak or smear water across your windshield instead of wiping it away cleanly. It’s hazardous, mainly because it’s a commonly underrated issue that drivers tend to overlook.
With reduced visibility, your reaction time is greatly affected, making it harder to anticipate and respond to potential hazards on the road.
2. Chattering, Squeaking, or Skipping Motion
Your windshield wipers should operate effectively without making funny noises. Ideally, your commutes should be cozy and silent, but squeaky wipers can ruin the experience.
If you hear a chattering, squeaking, or skipping sound when your wipers are running, it could indicate worn-out wiper blades or a really dirty windshield.
Wiper blades usually consist of rubber or silicone, so they degrade over time due to exposure to the elements. As a result, they become less effective in clearing water and debris off your windshield, leading to the noise.
Additionally, if your windshield is dirty or has residue buildup from products like wax or bug spray, it can cause the wipers to skip or chatter as they move across the surface.
3. Visible Cracks, Splits, or Bent Frames
Just like any other car component, windshield wipers break down over time. They may also absorb shock from debris and weather conditions, leading to cracks or splits in the rubber blades.
Splits and visible cracks can affect the wipers’ ability to properly clear your windshield by creating uneven contact with the surface. It leads to streaks and missed spots, compromising your visibility while driving.
The frames can also bend and flex as the wipers move, which can cause them to lose their shape over time. That’s how you end up with wipers that don’t make proper contact with the windshield, leaving streaks and missed spots.
Bent frames also make the wipers more prone to damage when you turn them on, as they may catch on the windshield and snap or break off completely.
4. Reduced Visibility in Rain or Snow
Another sign that you may need to replace your windshield wipers is reduced visibility in rain or snow. If you find yourself struggling to see through your windshield during inclement weather, it could be a sign that your wipers are not functioning properly.
Worn-out wiper blades can leave streaks, smears, and missed spots on your windshield, hindering your ability to see the road clearly.
Old wipers may also cause fogging on the windshield due to uneven water distribution. Visibility drops further, making driving in rainy or snowy conditions even more hazardous.
5. Dysfunctional Washer Fluid System
In addition to functioning wipers, it’s important to have a working washer fluid system. This system sprays a cleaning solution onto the windshield to help clear dirt and debris.
If your washer fluid system is dysfunctional, you may find yourself struggling to clean your windshield while driving. It’s especially problematic if you encounter unexpected road hazards or bad weather conditions.
Regularly check fluid levels and replace any old or dirty fluid. Also, inspect the nozzles for clogging and orient their aim towards the windshield.
How to Extend the Life of Your Wiper Blades
1. Clean Blades Regularly with Mild Soap and Water
Your silicon-based wipers interact with debris such as dirt, pollen, and dead bugs as they clean your windshield. Over time, these particles build up on the wipers and cause them to wear out faster.
You can extend their lifespan by cleaning them regularly with mild soap and water. Regular cleaning helps prevent buildups, ensuring your blades maintain their flexibility and effectiveness at clearing your windshield.
Mild soap and water are also gentle on your wipers, unlike harsh chemicals that can damage them and your car’s body paint.
Here’s more on how to clean windshield wipers.
2. Avoid Using Wipers on a Dry Windshield
Using wipers on dry windshields is not just ineffective; it’s also counterproductive. The abrasive motion of dry wipers on the glass can scratch and damage your windshield, leading to costly repairs.
It also wears out your wiper blades, even bending the wiper frame, which can cause streaking and reduce visibility.
If your washer fluid system isn’t working, avoid using your wipers and make prompt arrangements for a fix. You may still have to use the wipers in rainy or snowy weather conditions.
3. Park in the Shade When Possible to Prevent Rubber Damage
It’s common knowledge that hot sunshine emits harmful UV rays we can’t see. These rays cause premature aging, cracking, and hardening of rubber components on your car.
When you park under the blazing sun for an extended period, such as while at work or shopping, it can take a toll on your wiper blades, door seals, and tires.
Park in shaded areas whenever possible. Avoid trees that can drop sap or other debris onto your car, leading to messy cleanups later on.
4. Lift Wipers During Winter to Prevent Freezing to the Glass
During the colder months, ice and snow can accumulate on your windshield, making it challenging to see while driving. Even worse, your wipers can freeze on the windshield, making it almost impossible to clear the snow and ice off.
The probability of wipers freezing and getting stuck on the windshield is highest when you park your car overnight. You’ll often find that your wipers stick to the glass, and it’s very inconvenient to get them unstuck in the morning.
Always lift your wipers off the windshield when parking in winter weather to prevent them from freezing and sticking. Some people recommend placing a towel or piece of cardboard under the wipers overnight to keep them elevated and prevent ice buildup.
You need to up your inspection game in winter, as the cold temperatures and salted roads will wear out your wipers faster.
Professional Tip: Have Your Wipers Checked During Auto Glass Service
If you live in an area with harsh winter weather, always ask for your wipers to be checked during auto glass service. If not, you’ll soon be complaining that your windshield wipers are not working.
A professional auto glass technician will check the wipers for any cracks, tears, or other damage that may hinder their performance in winter conditions.
They can also adjust the tension of the wiper arms to ensure they have enough pressure to remove snow and ice buildup effectively. It will significantly boost your visibility while driving in treacherous weather.
Remember, proper wiper maintenance prevents windshield scratching or damage.
