Don't Drive In Haze, Remove Filmy Glare

You may have been able to ignore it for a bit, but at some point there’s no getting around it: The inside of the windshield a hazy mess that needs to be cleaned.

But where does that cloudy residue come from? And what gets rid of it?

The short answers are your interior and glass cleaners.

The oily haze on the windshield comes from airborne contaminants wafting off plastics, vinyls, carpets and polymers inside your vehicle.

A quality, streak-free glass cleaner will do away with spots and film on the inside of your windshield.

Applying a defogging product to the inside of a clean windshield provides a barrier against the residue in the future.

“Repellent products can be applied quickly,” said Ron Fausnight, group technical manager at Rain-X. “I apply them every time my car goes in for an oil change.”

Fausnight had some advice for cleaning and treating the inside of your windshield:

  • Use a glass cleaner designed specifically for automobile glass. They help prevent streaks. Streaks=glare.
  • Clean interior and exterior glass surfaces thoroughly before applying window treatment products.
  • Anti-fog products dissipate moisture, helping it evaporate. They are for use on the inside of a windshield.
  • Apply window treatment products with a terry cloth or microfiber towel. Spray the towel rather than the surface and wipe it evenly across the glass. Remove excess fluid with a clean, dry cloth to eliminate haze.
  • Avoid getting window treatment products on rubber surfaces. They contain alcohol, which can cause rubber to dry or crack.
