CLEANING THE INSIDE OF YOUR WINDSHIELD
Have you ever looked out while driving and noticed dirt on the windshield, only to clean it at the gas pump and notice that the smudges are still there? Yes, it can be annoying, and yes, it can be—and usually is—grime on the inside of the windshield. And it could be a number of things that cause dirt to appear in front of our eyes.
Dirt and grime can appear on the inside of a car’s windshield due to several factors:
- Off-gassing from Plastics and Vinyl
- The dashboard and other interior materials release volatile organic compounds (VOCs) over time, especially in hot weather. These compounds condense on the glass, leaving a hazy or greasy film.
- Dust and Dirt Particles
- Dust and dirt from shoes, clothing, and the air can circulate inside the car and settle on the glass.
- Smoking or Vaping Residue
- Smoke particles and tar can create a sticky residue that clings to the windshield.
- Human Contact
- Fingerprints, smudges, and oils from skin contact can leave streaks and marks.
- Condensation and Moisture
- Moisture inside the car can attract dirt and lead to water spots or streaks when it dries.
- Pet Dander and Hair
- If pets are frequently in the car, their dander and hair can contribute to buildup on the glass.
- Pollution and Air Vents
- Outside air entering through vents can carry pollutants and particles that stick to the windshield.
MAIN CAUSE
Remember that maintenance must be done regularly, perhaps once a month. The humidity in the air can cause a little moisture to form inside your windshield. This attracts dirt that then clings. As the day heats up and the humidity evaporates, that residue remains. This repeats daily, causing a build-up on the cleanest windshields and creating a haze.
Regular cleaning with a cleaner and microfiber cloth can help maintain a clear windshield. More on this . . .
