How To Clean The Inside Of A Windshield

Driving with a dirty windshield is dangerous and ugly! It can be a challenge to clean unless you know the best way to do it.

It’s vital that you be able to see out of your windshield while driving for optimal visibility and on-road safety. If you have learned how to detail a car, you probably followed steps on how to clean car windows too.  

However, you might not know how to clean the inside of a windshield. In this guide, we cover how to clean the inside of a windshield without streaks. 

What causes film on the inside of a windshield? Over time, dirt and grime build up on the windshield, leaving behind a hazy finish. This windshield haze can be distracting and make it more difficult to see what’s in front of you.  

Smoking is a major culprit for polluting the windshield and creating a haze. However, it’s not the only contaminant known to cause problems. The vinyl and plastic materials in your car are also dust magnets, which can get overrun and spill over to the windshield.

If you don’t clean the car interior often, all of this dust and dirt will go somewhere, and it’s normally onto the glass where it impedes visibility.
