10 Simple Step-by-step Guidelines on How to Keep Windows From Fogging Up When Raining

Step 1: Understand the Science Behind Foggy Window

Before we dive into the solutions, let’s get a better understanding of what causes foggy windows in the first place. When warm, humid air comes into contact with a cooler surface, it condenses and forms water droplets, which is what we see as fog on our windows. This usually happens when the warm air from our breath or body comes in contact with the cold surface of the car window.

Step 2: Keep Your Windows Clean

Dirty windows are more prone to fogging up as the dirt particles create more surface area for water droplets to condense on. Make sure to clean your windows regularly, especially during the rainy season.

Otherwise, the accumulated dirt and grime will only make it harder to see when it’s raining. You can use a microfiber cloth and glass cleaner spray to clean your windows or make your own cleaning solution by mixing equal parts of vinegar and water.

Step 3: Use an Anti-fog Solution or Shaving Cream

One effective way to prevent foggy windows is by treating them with an anti-fog solution or shaving cream. These products contain a special ingredient that prevents water droplets from sticking to the surface, thus reducing fogging.

Simply apply a small amount of the solution or shaving cream on your windows and use a clean cloth to evenly spread it across the surface. Let it sit for a few minutes before wiping off any excess product.

Step 4: Apply Rainx or Other Water-repellent Product

Another great solution to keep your windows clear during rain is to use a water-repellent product like Rainx. This type of product creates a hydrophobic barrier on the surface of the glass, causing water droplets to bead up and roll off instead of creating fog. You can apply it to your windows following the directions on the product label.

Step 5: Use Newspaper for a Streak-free Finish

If you’re not a fan of using chemical products, you can still achieve a streak-free finish by using newspaper. Simply spray some vinegar and water mixture onto your windows and wipe with crumpled-up newspaper.

The newsprint acts as a gentle abrasive, effectively removing any residue or streaks from the glass. It’s an inexpensive and eco-friendly solution that also works great for cleaning mirrors.

Step 6: Turn on the Air Conditioning

Another way to prevent your windows from fogging up is by turning on your car’s air conditioning. This helps reduce the level of humidity inside the car, making it harder for water droplets to form. You can also direct the airflow towards your windows to help them dry out more quickly.

You can also try setting the temperature to a cooler level than what you normally prefer, as this will reduce the amount of warm air circulating in your car.

Step 7: Use a Defogger or Windshield Wipers

If your car has a defogger, you can use it to help clear fog from the inside of your windows. Simply turn on the fan and adjust the temperature until the fog disappears.

Alternatively, you can also use your windshield wipers to clear any fog from the outside of your windows. Just make sure to use them on a low-speed setting to avoid smearing the water droplets and creating more visibility issues.

Step 8: Crack Your Windows Open

Sometimes, simply cracking open your windows can help prevent fogging by allowing the warm, humid air to escape and be replaced with cooler, drier air from outside.

This method is especially useful when you have a lot of passengers in your car, as their breath and body heat can contribute to the high humidity inside the vehicle. It’s a simple and effective way to keep your windows clear while driving in the rain.

Step 9: Check Your Air Filters

Dirty or clogged air filters can also contribute to increased humidity levels inside your car, which can lead to foggy windows. Make sure to regularly check and replace your air filters if needed to ensure proper ventilation and reduce the risk of fogging.

Regularly Check and Replace Your Air Filters

Otherwise, the damp air will continue to circulate inside your car and create more fog. You can consult your car’s manual for instructions on how to check and replace the air filters.

Step 10: Keep a Travel-size Dehumidifier in Your Car

If you frequently have issues with foggy windows, investing in a small dehumidifier designed for use in cars can be an effective long-term solution. These devices work by absorbing excess moisture from the air, preventing it from condensing on your windows. You can simply place the dehumidifier on your dashboard or under a seat, and it will work its magic without any effort required on your part.

Following these 10 simple steps on how to keep windows from fogging up when raining can help you keep your windows from fogging up when it’s raining, ensuring a safe and clear view while driving.

Whether you choose to use special products or opt for natural solutions, keeping your windows clean and dry is key to preventing foggy windows. So next time it rains, you’ll be prepared to conquer the fog and stay safe on the road.
