I only notice the windshield haze either during the morning commute. when the sun is streaming in and the dirty, hazy windshield is making it hard to see.
Or, when it is raining out in the winter and the salt has caked up on the windshield, creating a haze.
Unfortunately, parking and waiting for the rain to pass isn’t an option because I’m always running against the clock. S
The last thing you want while driving is for something to obstruct your view of the road. And that’s what makes windshield haze a foe. Haze buildup is a common occurrence.
Thankfully, it doesn’t take a genius to get rid of it. Here’s a quick guide on how to keep your windshield crystal-clear.
What Causes Windshield Haze & What Removes It!
Interior Windshield haze is a thin film buildup made up of airborne contaminants from interior materials, pollutants, gassing, and cleaning products. Let’s have a closer look at some of the common causes of hazy windshields.
Exterior haze is generally from salt, road grime, pollen or pollution.
What Causes Windshield Haze?
Cigarette smoke leaves a yellowish residue on the inside of the windshield. If you smoke regularly in your car, you’ll begin to notice a buildup of smoke residue in the sides of your windshield. It’s safer for you and others to smoke outside of your car.
Offgas from vinyl or plastic
As direct sunlight heats your car, the vinyl and other plastics begin to break down and evaporate onto the windshield. It often happens during the summer, and new cars are more susceptible to offgas from vinyl or plastic.
Water & Mildew From The Floor
Liquid or moist substance within your vehicle can cause a haze to form on the inside of the windshield. Maybe you have an open bottle of water, or there’s mildew in the fabrics of parts of your car that never dried out. You need to get rid of all of those.
Engine or heater coolant leak
An engine or heater coolant leak can enter your vehicle through the front vents and form a green haze on your interior windshield. It has a strong smell and is not hard to miss.
Hard water, acid rain, dirt, & salt on the outside
An exterior windshield haze isn’t any different from an interior one. It may be caused by acid rain, hard water, dirt, pollen, or sea salt. If you live near the sea, you’re going to have this salt problem often.
