How to Clean the Inside of Your Car Windshield

Cleaning the inside of your car’s windshield is important for safety and aesthetics. Over time, it can become dirty with smudges with fatty streaks, making it harder to see and becoming a safety risk. Water vapor inside your windshield (On rainy and cold days) can also reduce visibility and is another major safety concern.

Regardless of which cleaner you choose, the process is relatively simple.

First, remove any loose dirt or debris from the surface of the windshield.

Next, wet a clean microfiber cloth with your chosen cleaner and wipe down the windshield.

Be sure to clean all the nooks, crannies, and edges where the windshield meets the dashboard.

Once you’re finished cleaning, dry the surface with a clean, dry cloth.

If your windshield is filthy, you may need to repeat the process a few times. But with regular cleaning, you can keep your car’s windshield looking new.

Or cold and rainy days when there is a significant temperature difference between the inside and outside of your car, the inside of the windshield tends to get foggy from vapor.

What is the best way to clean the water vapor as fast as possible?

The worst thing you can do is to try to wipe it off with your hand or even a cloth. This will leave streaks, causing the headlights of oncoming traffic to distort with a blinding effect.

The second worst thing is to turn on your car heater; this will make it worse. Think about it. The reason for the vapor in the first place is that it is warmer inside the car than outside. Turning on the heater will have a compounding effect and make it worse.

So what is the best way to do this?

This answer is counterintuitive, considering it is possibly already cold inside the car, but here it comes…Turn on your car aircon on the windshield fan setting and the vapor will disappear in a minute or two. That’s it! No streaks and no smudges.


Keeping your car’s windshield clean is essential for both safety and aesthetics. There are a few different ways to clean it, but the easiest way is to make your own window cleaner using rubbing alcohol and water.

If your windshield is filthy, you may need to repeat the process a few times, but with regular cleaning, you can keep it looking new.

In addition to keeping the outside of your car clean, keeping the vapor from inside the vehicle off the windshield is also important. The best way to do this is by turning on your car’s air conditioner on the windscreen fan setting.
