Most drivers experience the same issues while on the road. One of the most common among them is haze appearing on the windshield when it rains. Not only is windshield haze annoying but it can also be dangerous, especially when driving at night. 

If this is a problem you’ve been dealing with on occasion as well, coming up with a solution is a must. With that said, let’s take a look at how to make sure your windshield is spotless at all times.

How does haze form?

Before we go on about how to get rid of haze from your windshield, let’s discuss how it appears in the first place. What not all drivers are aware of is that there are multiple reasons why haze can form. We’ll discuss some of the most common ones as well as how to deal with them.

Blade vipers haze

While on the road when it rains, the only way to keep driving is to turn on your wiper blades. When they pass over your windshield, the haze forms but quickly evaporates. Then, your vipers repeat the cycle thus causing constant appearance and disappearance of haze from your windshield. 

The problem arises when haze starts evaporating slowly and blades just keep smearing the water on your windshield. While it wouldn’t be possible to stay on the road when it rains without the viper blades, haze is still an issue that can make driving more difficult. This is especially the case at night when you’re faced with the incoming traffic. It’s the combination of haze and headlights that makes seeing the road extremely tough.

Vinyl and plastics haze

Another common reason why haze forms are vinyl and plastic parts in the car. When the vehicle is heated, vinyl and plastics can vaporize, resulting in the windshield getting blurry. The easiest way to deal with this issue is to grab a microfiber cloth and clean it. However, once you do that, you’ll often find the haze to remain on your windshield.


Smoking inside the car is also a common culprit when it comes to haze on the windshield. The biggest problem with it is that the haze built up due to smoke can be more difficult to remove. To check if this is the source of the haze on your windshield, just grab a towel and clean it. If the towel turns yellow, it’s the smoke that causes haze on your windshield.

How to get rid of haze?

Whether you’re a brand new car owner or a seasoned driver, built up haze can cause a lot of trouble on the road. It makes a lot of sense to find a way to deal with it and make sure you stay safe when driving in the rain. The good news is that there are a few different solutions and you should be able to find the one that works for you.

Windshield wax

Waxing your car will often get the job done, especially if you want to say goodbye to viper blades haze. It’s up to you to decide whether you want the windshield wax or just regular wax. No matter which path you go down, make sure you don’t overdo it. If you apply just enough wax to your windshield, it’ll form a thin coat, aiding in getting rid of water rather than just smearing it when it rains. As a result, your windshield will stay clean and you’ll have a much better view of the road.

Hydrophobic coating

One of the most effective ways to prevent water from damaging your vehicle in general is to apply hydrophobic coating on it. An additional protective layer will not only keep your windshield from all sorts of contaminants but it’ll also make dealing with haze much easier. There are a number of hydrophobic coatings on the market and you’ll be guaranteed to find the one you like. The application shouldn’t be tough and you’ll have extra water protection in no time.

Water and white vinegar

Any built-up haze you spot on your windshield should be dealt with in a timely fashion. Get rid of it and not only will you be safer on the road but you’ll find driving to be less stressful as well. Luckily, there are some simple home remedies for built-up haze and water and white vinegar solution is one of them. All you need to do is mix up a spray bottle with a 1:1 white vinegar to water ratio and spray it on your windshield. If you find the haze to be more severe, you can make the solution stronger by adding more vinegar. This is the best way to clean the windshield from the inside of the car and make sure haze doesn’t affect the time you spend on the road.


If you were wondering how to clean the inside of windshield when in a hurry, rubbing alcohol onto it is a solution for you. Alcohol is known for breaking down hard substances and it dries quickly. Most importantly, it doesn’t leave streaks, meaning that your windshield will stay spotless and driving in harsh weather conditions won’t be as tough as it seems.

Over to you

Haze on the windshield when it rains can cause a lot of trouble, even to the most experienced drivers. However, as long as you clean your windshield on a regular basis and take precautions to prevent haze, you’ll be able to drive safely when it rains.
