How Does the Inside of Your Windshield Get Dirty?

Before we officially jump into the step-by-step guide on how to clean the inside of your windshield, we first discuss why there’s even dirt there in the first place.

“It isn’t as exposed to dust like the outside of the windshield, why is it dirty?”

“I barely touch it, why is it dirty?”

You’ve probably asked these two questions at least once and never really got answers.

Read on to see the top culprits of dirty windshields.

Car off-gassing

Off-gassing is probably the biggest contributor to the dirt inside of your windshield. However, most people don’t know this as off-gassing isn’t an instant and one-time thing. The substances and particles accumulate on your windshield slowly which is why it often goes unnoticed.

Your car dashboard is made of plastic that contains a lot of harmful chemicals. When the dashboard is exposed to sunlight and heat, the plastic breaks down.

As the plastic breaks down, chemicals are then released into the air and cling unto the inside of your windshield.

Dust and dirt

When you clean the inside of your car, most of the dust and dirt from the seats, carpets, and the dashboard eventually end up on your windshield.

This is why they always advice to clean the windows and windshield last as dust and dirt from other parts of the car can end up there.


Be it fingerprints from pointing the directions, fingerprints of your children, or even   nose prints and licks from your pet. If left uncleaned, these prints can accumulate and cause your windshield to be dirty.

Step by Step Guide on How to Clean the Inside of Your Windshield

Be properly equipped before you start the job. Here’s a list of the things you will need.

Materials you will need

  • Microfiber towel
  • Your choice of auto glass cleaner
  • Rubbing alcohol

Cleaning steps

  • Wipe the windshield with a clean and dry microfiber towel to remove all the dust and the dirt.
  • Take the rubbing alcohol and apply it on another clean microfiber towel. Wipe this all over the windshield to get the grease out.
  • Spray the clean side of your microfiber towel with the glass cleaner and then wipe your windshield in a circular motion.
  • Use the clean side of your dry microfiber towel to wipe the windshield dry.

Pro tips

  • Wipe your windshield under the shade where the temperature is cooler. This will help slow down the evaporation of your glass cleaner as you clean.
  • Clean your windshield and windows last. As mentioned above, a lot of the dirt from the seats and carpets end up on the windshield and windows. So it’s best to clean them last to capture all the dirt.
  • Always have a separate microfiber towel for your windshield and windows. Using the same microfiber towel in cleaning different parts of your car will leave unwanted oil, wax, and other compounds on your windshield and windows.
  • Having a separate microfiber towel isn’t enough. You also have to make sure the microfiber towel is 100% clean and unused or you’ll still end up with an unclean and hazy windshield.


Can you use Windex on your windshield?

Yes, you can use Windex on your windshield. There may be a lot of different opinions that can cause confusion when it comes to using Windex or other ammonia-based cleaners on your windshields.

However, there really isn’t much proof that using such cleaners can actually damage your windshields.

If your windows were tinted by a third party and you want to be on the safe side, make sure to check in with them before you decide to use Windex on your windshield.

On the other hand, if your windows were tinted by the manufacturer, then you should have no issues with using Windex.

Just a pro tip, make sure that the cleaner only stays on your glass and off your leather seats as Windex and other ammonia-based cleaners can damage them.

How often should you clean the inside of your windshield?

Different people have different cleaning preferences. So, as to how often you should be  cleaning the inside of your windshield really depends on your personal preference.

If you like to keep things neat and clean all the time, cleaning the inside of your windshield every time you clean your interiors can be a good practice.

This way, you also get to save time and energy as you only have to do a thorough cleanup in one go.

Can you use vinegar to clean your windshield?

Yes, you can use vinegar to clean your windshield. If you’re up for a little DIY project, then you should give up the glass cleaners and give vinegar a try.

Vinegar has been known to be very effective in taking out the dust and dirt on windshields. In fact, a lot of people actually prefer using vinegar over the other glass cleaners available in the market.

What do car detailers use to clean the windshield?

Most professional car detailers use a waffle weave microfiber towel. Microfiber towels ensure that your glass is left crystal clear, free from all the haze and streaks.

But what’s their secret?

Moisture. Just make sure there’s enough moisture in the towel so you get that professional finish on your glass windows.


Driving around with hazy windshields can be very stressful and knowing the causes of dirty windshields is one way you can easily avoid those hazy drives in the future.
