Why is your windshield getting dirty?

Common culprits include kids' fingerprints, pet noses, smog, road dust, and sea salt.

Lesser-known: Interior plastics and vinyls degrade over time, releasing vapors—like that "new car smell." The windshield's slant traps these oily residues.

Oily dashboard cleaners worsen it, especially in heat and humidity, forming a stubborn film.

How to keep your windshield clean longer?

Ventilate daily by opening doors and windows to disperse fumes and refresh air.

Park in shade or a garage to minimize heat buildup and off-gassing.
