How To Clean Inside Of Windshield

Wiping inside of my windshield with the glass cleaner

A clean windshield ensures the general safety of those who are in the car including the driver.

This is because the windshield needs to be clearly visible for the driver when they are on the road to avoid collisions.

At times the outer windshield is not the problem, and instead the inner side is the problem.

Do you know how to clean inside of the windshield? The car windshield can be cleaned on the inside using the following steps and using the following cleaning agents:

  1. Cleaning The External Parts Of The Car First
  2. Wipe Using A Dry Microfiber Cloth
  3. Get Rid Of The Grease Or Oil On The Surface Of The Windshield
  4. Get The Class Cleaner

Cleaning of the windshield on the inside needs to be done regularly. This is due to the nature of the dirt that forms on it, when left on its surface for long. It will be tough and hence will not come out easily.

What Causes Your Car Windshield To Get So Dirty?

Over time you will realize that the car windshield gets dirty or even foggy than before.

If when you try to clean the outer side, you will notice that it does not get any cleaner than before, then the inside of the windshield needs cleaning.

However, unlike the outer side the inner side does not get cleaned quite easily as the dirt here is not normal such as simple dirt particles.

This even gets difficult to clean if you rarely clean your car windshield from the inside as the dirt particles get more attached to the surface of the windshield.

The following are what causes your car windshield to get dirty over time:

1. Frequent Smoking In The Car

If you smoke or frequently carry passengers who smoke, then your car windshield will get dirty.

This is because the smoke particles from the cigarette will stick to any part of the car, not leaving behind the inside part of the windshield.

If you want to avoid this, you should walk out or have that person walk out and have their smoke while not in the car.

They may also opt to smoke close to the window and let the smoke escape before getting to the surface of the interior of the vehicle.

2. A Dusty Car

You might frequently drive in a dusty terrain and this makes dirt particles get into the car through under the windows or any other opening.

These particles would then settle on the surfaces of the vehicle including the inside part of the windshield.

You may not realize the dirt particles on the windscreen as they attach to the glass and when you clean with an ordinary rag, the particles become stubborner and stick to the windshield.

Over time, they become almost permanent and getting rid of them is not easy.

3. Outgassing From The Plastic Components Of Your Car

The plastics and vinyl used in the manufacture of components of the interior of the car break down in a process that is catalysed with high temperatures.

This releases oils that escape in gaseous form and then stick to the inside part of the windshield.

The gas then lands on the inside part of the windshield which then cause impaired visibility when the driver is on the road.

On ordinary cars, the heat that catalyses this reaction is from the sun and this lead to the inside of the windshield being quite foggy with time.

By the way, you can learn how to defog your windshield here.

Such type of dirt on the surface on the windshield can’t be cleaned with an ordinary cloth and just using water and soap or a detergent.

You need an ideal cleaning agent to get this done as oil can’t just be cleaned with anything.

4. Other Factors That Lead To the Windshield Getting Dirty

Contact on the windshield with dirty items such as dirty hands, a dusty rag or any other thing will get the windshield dirty from the inside.

Some car owners normally have a rag on their dashboard for cleaning the inside part of the windshield, this is a rag they rarely clean yet use it for cleaning the inside of windshields and any other part on the dashboard.

This would be worse if you do not get it cleaned soon enough with a proper cleaner and cleaning agent as the dirt will settle and stick on the surface.

Dust and dirt particles that are normally the case when you frequently drive through dusty terrains.

This would be even much worse if you had your windows open and the dust particles get in. They will then proceed to enter the car and settle on the inside part of the windshield.
