Getting a scratch on your car’s windshield is as annoying as much as it is dangerous. It is also a commonplace occurrence. A car windshield scratch can hinder the driver’s visibility and compromise passengers’ safety. So it is imperative to resolve the problem quickly, especially when the scratches are minor. Once you’ve identified the cause of the scratch and how deep the damage is, you can figure out the best way to deal with it. 

What is a Windshield Made of?

Windshields are made of laminated glass that offers the highest degree of safety against injuries and accidents. The laminated glass consists of three layers – a layer of vinyl between two sheets of glass — all stuck together under extreme heat and pressure in a specialized oven known as an autoclave.

Because of this construction, only the outer layer of the windshield sustains damage (typically minor scratches) in the case of moderate impact. Such scratches can be fixed without the need for a complete car windshield replacement. 

Why Does a Scratch on Your Windshield Deserve Attention?

Your vehicle’s front glass provides structural integrity to the car, and a damaged windshield can affect the car roof’s strength. A crack, scratch, or chip can bring the whole roof down in case of a collision or traffic mishap. And if you are driving with a cracked windshield unattended for a long time, it poses the danger of caving in in case of some heavy, even mild external impact.

Car window glass repairing and replacement is also crucial because a small chip is just a disaster waiting to take place – it can spiral into a large and deep crack soon which only a replacement may suffice.

Additionally, the car front glass also supports the appropriate and timely deployment of the front airbags; however, once damaged, its ability to do so correctly is affected, severely exposing the life of occupants to danger.

What Can Cause Scratches on Your Windshield?

There is a multitude of everyday things that can cause damage to a car’s windshield.

Defective Wiper Blades

The surface of the windshield’s wiper blades, upon aging and neglect, can become hardened, causing scratches, especially when the glass is dry. The same can happen if there is a small object, like a pebble, trapped under the blades.

Damaged Ice Scrapers

If you live in a cold, snowy area, you may have to remove ice from your car windshield and windows from time to time. Tools like ice scrapers are made to protect the windshield, but if they become old and damaged, they can cause scratches.

Improper Cleaning

If you use a rough cloth to clean your windshield, scratches can appear on it now and then. Using a soft microfiber or cotton cloth is the best way for safe and proper cleaning.

Road Debris

Scratches are also caused by rocks and pebbles flying into your windshield off the road, especially when you are driving behind four-wheelers as they trap-rocks on the road easily. 

Preparing to Fix Scratches

The first step in fixing a scratch is determining if it is a surface scratch or a deep scratch. A shallow surface scratch will feel smooth to touch when you run your finger across it. A deep scratch, though, will grow over time and may even need a complete car windshield replacement. You can arrest the speed at which the scratch grows at home, but the best course of action will be to seek professional help.

However, the good news here is that you can easily prevent this from happening by employing a few safety measures beforehand. Here are some tips to keep the scratches at bay.

Wipers – The Most Important Tool for a Scratch-Free Windshield

Car wipers are easily the most taken-for-granted functionality in the car and must be given regular attention if you want a gash-free windshield.

Ever got a pesky leaf stuck in your wipers that won’t budge. Well, just flick the wipers on, and you’ll get rid of them, right? Well, no. Running your wipers on a dry car windshield is a perfect recipe for disaster. An overnight park in the parking lot is enough for the dust and the dirt to settle on your windshield. As a result, if you run a dust-laden wiper over your car windshield, it may have the same effect as a reliable old sandpaper rub.

That’s why you should always get your car windshield a little wet before wiper application.

Moreover, wiper blades don’t last forever, unfortunately. A wiper’s rubber is exceptionally susceptible to becoming brittle and breaking down under the punishing Indian sun. So, if your wiper blades are in poor health, the metal brackets which house them can come in contact with your car windshield, resulting in a scratch-fest and rendering your windshield almost opaque.

Ergo, it would be best if you rid yourself of the wiper blades at the first sign of disintegration and get yourself a new one. They’re quite an inexpensive investment and play a significant role in your safety.

Top up your Wiper Fluids

One of the easiest ways to ensure a scratch-free windshield is to simply keep the wiper fluid reservoir filled at all times. A suitable wiper fluid plays a more significant role in windshield maintenance than you might expect. Also, a bottle of high-quality wiper fluid is relatively inexpensive and wouldn’t hurt you in the least if you had it stocked in your garage all year round.

Also, for the sake of your wiper blades’ cleanliness and health, make sure your wiper fluid is checked regularly, preferably once per month.

However, if you want to protect your windshield from scratches, remember to top it off whenever you are at the fuel station and follow these tips to give your car windshield and wipers some love that they deserve.

Use the Right Cloth and Right Cleaner

Scratches can also pop up on your car windshield through improper or insufficient cleaning of the glass. Therefore, to clean your windscreen correctly and without causing additional damage, use a soft microfiber cloth during wipe downs. Don’t forget to properly pre-rinse your car windshield nice and wet when you start cleaning it.

Also, make sure to use a cleaner free of ammonia when cleaning your windscreen. Using an ammonia-based cleaner can dehydrate your car windshield‘s glass, causing discoloration and cracks.

 Park Your Car the Right Way

Parking your car out in the open is bound to introduce your windshield to some foreign objects, such as leaves, debris, and a whole lot of dust. This exposure can lead to an excess of minor scratches on your windshield, which aren’t quite visible to the naked eye. These little scratches can develop into more prominent ones over time, ultimately leading to an unusable windshield and an un-drivable car.

So, it’s better to park it in an enclosed space, preferably a garage, to protect your car’s windshield from any gashes. Plus, as an added benefit, parking your car in a confined spot also helps regulate its internal temperature.

Get Small Scratches Fixed Right Away

If your car windshield is already adorned with some minor scratches, you must fix them immediately, lest they transform into more prominent, scarier scratches.

It is recommended to repair it at a reputed car-care service since standard or sub-standard service will do more harm than good. Though a renowned service will cost you more, it will save you expenses in the long run.

Before you start dealing with the scratch, clean your windshield with soap and warm water, unless there is a risk of the scratch expanding. Mark the area to be repaired with a dry-erase marker on the undamaged side. 

7 Ways to Deal with Windshield Scratches

After figuring out the seriousness of the scratch, you will need to get hold of a few equipment for windshield crack repair. If you have an automotive parts store or repair shop near you, you will be able to get your hands on most equipment.

Glass Repair Kit

A glass repair kit can be bought online or at an automotive parts store nearby. It is a good option to repair scratches that are relatively deep but not deep enough for the windshield to fall apart.

Step 1: Apply the rubbing compound from the kit to the scratch. The rubbing compound contains cerium oxide which chemically reacts with the glass to seal the scratch and stop it from deepening. It works by forming a cerium-oxygen-glass compound which is softer than glass and can bond the scratch together.

Step 2: Let the compound dry for 30 minutes.

Step 3: Clean the area with a soft cloth.

Clear Nail Polish

Clear acrylic nail polish is readily available at shops, but can only be used for the shallowest of scratches. Since it hardens as it dries, it works well for minor repairs.

Step 1: Apply a layer of nail polish on the scratch and clean off the excess.

Step 2: Let the nail polish dry.

Non-Gel Toothpaste

Non-gel toothpaste will work only for minor scratches and should not be used for deep ones. The toothpaste acts like a grinding paste that takes away a small part of the glass around the scratch, leveling the entirety of the damaged area.

Step 1: Dry the glass using a lint-free cloth.

Step 2: Apply some toothpaste to a soft cloth.

Step 3: Rub the cloth over the scratch in a circular motion for 30-40 seconds.

Step 4: Wipe the toothpaste away with a damp cloth and use the lint-free cloth to dry the area again.

Acrylic Scratch Remover

An acrylic scratch remover is an easy solution for small scratches and is available at any automotive parts store. This product fills scratches in and chemically reacts with glass to fix it.

Step 1: Apply a small amount of remover on a cotton cloth.

Step 2: Rub the cloth over the scratch for about a minute.

Step 3: Let the remover sit for 20-30 minutes.

Step 4: Clean the glass with a soft cloth.

Step 5: Gently buff out any remaining damage.

Glass Scrub Compound

A glass scrub compound is typically used to clean off stubborn dirt and grime from glass, but can also be used to fix minor surface scratches on car windshield glass; it can be quite abrasive if rubbed on the glass for a long time. It works similar to a toothpaste – by leveling the glass around the scratch and hiding the damage.

Step 1: Apply some of the compounds on a damp microfiber cloth.

Step 2: Rub the cloth on the scratch with a rotational motion with even pressure.

Step 3: In between every few rotations, spray the area with a little distilled water. Make sure the area does not dry while you are rubbing it or it can cause a number of fine scratches.

Step 4: Apply minute amounts of the compound repeatedly.

Step 5: Repeat the process regularly over a couple of days until the scratch is no longer visible.

Buffing Machine with Water Pump

A buffing machine with distilled water can also level out the area around the scratch and fix it. This should only be done for minor scratches because leveling out the windshield area around a deep scratch would cause extensive damage.

Step 1: Cover the body of the car around the windshield with plastic sheets or rags.

Step 2: Make a dam out of several layers of duct tape on the windshield to use the water efficiently. This can be done by sticking one strip of duct tape vertically on the surface and sticking another piece to its sticky side. Repeat the process but now with the tape stuck horizontally.

Step 3: Pump the distilled water and buff the area until no more damage can be seen. Be patient and do not use too much pressure.

Step 4: Clean up the residue from the windshield and remove the coverings from the body of the car.

Professional Help

If the damage is too deep to repair at home or if you are unsure about repairing your windshield at home, it is best to seek professional help. In case of a deep crack, the windshield is completely replaced.

Step 1: The black pieces holding your windshield in place, called the trim, are removed.

Step 2: The windshield is lifted away with large suction cups.

Step 3: Old urethane, dirt, and dust are cleaned out from the pinch weld and new urethane is applied to the edges.

Step 4: The new windshield is lowered into the car with suction cups, held in place for some time, and allowed to dry. 

How Can I Avoid Scratching my Windshield in the Future?

You can keep your windshield safe from harm by maintaining distance between your vehicle and large trucks driving in front of you. Parking in the shade can also keep your windshield strong as high temperatures cause the glass to expand and weaken over time.
