Your Windshield Looks Clean Until the Sun Hits It — Here’s How to Fix That

A windshield can look spotless in the driveway and turn into a blurry mess the moment the afternoon sun hits it. Suddenly, every wipe mark, greasy streak, and mysterious haze appears right in the driver’s line of sight. That annoying film usually needs more than another swipe with a paper towel.

The fix starts with identifying what actually coats the glass. Dust, road grime, dashboard vapors, oily residue, and leftover cleaning products can all contribute to a cloudy windshield. Use the wrong cloth or cleaner, and you may spread the mess instead of removing it. Fortunately, a few inexpensive supplies and a better cleaning routine can make a noticeable difference.
