3 Super Simple and Effective Ways: How to Clean Inside of Windshield (Actually Tested)

Written by Oliver

You probably clean the outside of your windshield regularly during a car wash or by hand, but what about the inside?

It can be challenging to see through a dirty windshield, and grime build-up can also obstruct your view.

Fortunately, there are a few simple ways to clean the inside of your windshield and keep it looking crystal clear.

First is to use a microfiber towel. Just dampen the towel with glass cleaner and wipe down the windshield surface. You can also use a dry microfiber cloth to remove water stains.

The second way is to use vinegar. Simply mix one part of vinegar and two parts of water in a spray bottle and spray it onto the inside of the windshield. Then, use a microfiber towel to wipe away the grime.

The third way is to use an alcohol-based cleaner. Alcohol-based cleaners are excellent for deep cleaning.

Avoid using ammonia-based cleaners or dishwashing liquid.

Why It’s Crucial to Keep a Car Windshield Clean?

Although it may seem minor, keeping your windshield clean is crucial to your safety on the road.

Dust and dirt can quickly build up, obscuring your view and making it difficult to see what’s ahead. This can increase your risk of being involved in an accident, as you may not be able to react in time if something suddenly appears in your path.

In addition, a dirty windshield can also make it harder to see at night, when dust and dirt are more likely to reflect light from oncoming headlights.

By taking a few minutes to clean your windshield regularly, you can help ensure that you have a clear view of the road ahead and that you arrive at your destination safely.

A Dry Microfiber Towel or Vinegar Helps Against Water Stains

If you’re dealing with water stains on the inside of your windshield, there are a few things you can do to remove them.

First, try dry microfiber cloth. Simply wipe the cloth over the stained area in a circular motion until the stain is gone.

If that doesn’t work, vinegar may do the trick. Mix one part vinegar and two parts of warm water in a spray bottle and spray glass cleaner the solution onto the stain. Let it sit for a few minutes, then wipe it away with a dry paper towel.

If all else fails, use rubbing alcohol. Or you can always take your car to a professional for a thorough cleaning.

Advantages of Microfiber Towel in Auto Glass Cleaning

Microfiber cloths have quickly become a popular choice for auto glass cleaning, and it’s easy to see why. Made from a new type of synthetic fiber, microfiber towels are much more absorbent than traditional cotton towels.

As a result, they can help to remove more water and eliminate streaks more effectively. In addition, new microfiber towel is less likely to scratch the surface of the glass. It can be used without spraying any chemicals, so your glass remain completely dry!

To clean windshield with a microfiber cloth, simply wet the towel with glass cleaner and then use small, circular motions to wipe away dirt and grime. Once you’re finished, be sure to dry the glass completely to prevent new streaks from forming.

With their many advantages, it’s no wonder that microfiber towel are becoming the towel of choice for many car owners.

Use Alcohol-Based Glass Cleaner for Deep Cleaning

If you’re looking for a deep clean for your windshield on car windows, an alcohol-based glass cleaner is a way to go.

Unlike traditional spray glass cleaners, rubbing alcohol will cut through any residue, grease, or dirt that may be on your windshield. This will make it a lot easier to get windshield cleaned properly.

However, it’s important to use rubbing alcohol in moderation. If you use too much, it will be difficult to wash alcohol away, and you’ll end with a pungent stink inside the car.

As long as you use it sparingly, an alcohol-based glass cleaner is the best way to get a deep clean for your windshield.

It Can be Dangerous to Use Ammonia-Based Window Cleaner

When it comes to keeping your car’s windows clean, it’s essential to be mindful of the products you use.

Ammonia-based window cleaners are popular because they’re effective at cutting through dirt and grime. However, they can also be dangerous for your car’s parts and tinted car windows.

The ammonia in the cleaner can break down the tint, causing it to fade and become less effective at blocking out UV rays.

In addition, the ammonia-based glass cleaners can leave behind streaks while applied during direct sunlight.

Over time, the ammonia will damage the car materials, causing them to become brittle and prone to cracking.

This chemical can also cause severe irritation to the eyes, throat, and skin. For these reasons, it’s important to be careful and use nitrile gloves when using ammonia-based cleaners on your car.

Always consult the product’s label when in doubt, or take your car to a professional detailer for proper cleansing.

Use Paper Towels or Cloth to Protect the Dashboard During Glass Cleaning

One important thing while cleaning the inside of your windshield is protecting the dashboard.

The dashboard is made of plastic and it’s one of the most important car’s surfaces in the interior.

When cleaning the windshield, use paper towels or a clean cloth to cover the dashboard so it’s protected from glass cleaner or rubbing alcohol.

You can use the same cloth to wipe a dashboard after windshield cleaning, so you will end up with a shiny and clean car’s interior!

Don’t Use Dishwashing Liquid as a Car Glass Cleaning Solution

You may have seen commercials where a woman washes her car with dishwashing liquid, and it looks amazing!

However, what they don’t show you is that if you use dishwashing liquid as a glass cleaning solution, it will leave streaks.

A lot of water is used in the dishwashing process, meaning soap residue is left behind. When this residue dries, it can leave streaks on the inside of your windshield.

In addition, dishwashing liquid is not designed to remove things like bugs or tree sap, so it’s not the most effective glass cleaning solution for your car.

Save the dishwashing liquid for your dishes and use a dedicated glass cleaner for your car.

What to do if Visibility Through the Windshield is Still Bad After Cleaning

If your windshield is still blurry after you’ve cleaned it, it may be time for a replacement. Over time, deep scratches can mar the surface of your windshield, making it impossible to see clearly through it.

In addition, exposure to the elements can cause the windshield to become foggy or hazy. If you’ve tried cleaning it with vinegar, water, and soap, but it’s still not clear, it’s time to get a new one.

A new windshield will provide you with a clear view of the road and help you stay safe while driving.
