A fogged-up windshield is more than just an annoyance; it’s a serious safety hazard, drastically reducing visibility and increasing the risk of accidents. Imagine navigating a busy intersection or winding mountain road with only a blurry view of what lies ahead. Furthermore, frantically wiping at the condensation while driving is distracting and dangerous. Fortunately, several preventative measures and quick fixes can ensure a clear view and a safer driving experience, regardless of the weather conditions. From simple adjustments to your vehicle’s ventilation system to utilizing readily available products, keeping your windshield fog-free is easily achievable. So, let’s explore some practical solutions to this common problem and ensure clear vision on the road ahead.
One of the most effective ways to prevent windshield fogging is by understanding the underlying cause: humidity. Essentially, the moisture in your breath, combined with the cooler temperature of the windshield, causes condensation. Therefore, manipulating the temperature and airflow within your car can make a significant difference. For example, turning on the defroster and directing the airflow specifically towards the windshield is a crucial first step. Moreover, ensure the air conditioning is activated, even during colder months, as the A/C system dehumidifies the air. Additionally, slightly cracking a window can improve ventilation and further reduce humidity. Another often overlooked tip involves keeping the inside of your windshield clean. Dirt and grime can attract moisture, exacerbating the fogging issue. Consequently, regularly cleaning the inside of your windshield with a glass cleaner can improve visibility and minimize fog build-up. Finally, consider using specialized anti-fog products available at most auto parts stores. These products create a barrier on the glass, preventing moisture from condensing.
Beyond these preventative measures, there are also several quick fixes for when fog appears unexpectedly. While driving, resist the urge to wipe the condensation with your hand or a cloth, as this will only smear the moisture and worsen visibility. Instead, continue using the defroster and A/C, adjusting the temperature and airflow as needed. Furthermore, if you have a reusable dehumidifying bag or pouch, placing it on your dashboard can absorb excess moisture and prevent further fogging. In addition, consider carrying a dedicated microfiber cloth for cleaning the windshield. Unlike paper towels or regular cloths, microfiber effectively removes moisture without leaving streaks or residue. Ultimately, being prepared with these strategies and tools will keep your windshield clear and improve driving safety, ensuring peace of mind in any weather conditions. Remember, clear visibility is paramount for safe driving, and taking these simple steps can make a world of difference.
Preventing Fog Before It Starts
Fog on your windshield is a nuisance, and sometimes even a safety hazard. Luckily, there are several proactive steps you can take to prevent it from forming in the first place, saving you time and hassle.
Adjusting Your Climate Control
Your car’s climate control system is your best friend when it comes to battling fog. It might seem counterintuitive, but using the air conditioner (AC) is one of the most effective ways to defog your windshield. The AC removes moisture from the air, which is the root cause of fogging. Even in colder weather, turning the AC on for a few minutes can clear things up quickly. Direct the airflow specifically towards the windshield for maximum impact.
Maintaining Proper Ventilation and Airflow
Temperature Equilibrium
One of the main culprits behind windshield fogging is the temperature difference between the inside and outside of your car. When warm, moist air from inside your vehicle comes into contact with the cold windshield, it cools rapidly and the moisture condenses, forming those pesky little water droplets we know as fog. Think of it like a cold glass of water on a hot day – the moisture in the air condenses on the outside of the glass. The same principle applies to your windshield.
Ventilation Strategies
Increasing ventilation helps to equalize the temperature inside and outside your car. This can be achieved by cracking open a window, even slightly, especially during short trips. It allows for the exchange of air, preventing the buildup of humidity inside. Utilizing the fresh air setting on your climate control system can also be incredibly effective. This draws air from outside the vehicle, rather than recirculating the air within the cabin, which can become saturated with moisture.
Managing Interior Moisture
Another key factor in preventing fog is minimizing the amount of moisture inside your car. Avoid leaving damp items like umbrellas, wet coats, or gym bags in the vehicle, as these contribute to humidity. Regularly wiping down the interior of your windshield with a clean, dry cloth can also remove any residual moisture that could lead to fogging.
Material Considerations
Even the materials in your car can play a role. Fabric car mats, for example, tend to absorb moisture, while rubber mats are easier to keep dry. If you live in a particularly humid climate, consider switching to rubber mats to help reduce moisture inside the vehicle.
| Ventilation Technique | Benefits | Considerations |
|---|---|---|
| AC | Quickly removes moisture | Can slightly reduce fuel efficiency |
| Cracking a Window | Simple and effective for short trips | Can be uncomfortable in extreme temperatures |
| Fresh Air Setting | Constantly replaces humid air | May not be as fast as AC |
Using Anti-Fog Products
A variety of anti-fog products are available on the market, including sprays, wipes, and even reusable cloths. These products create a thin, transparent layer on the windshield that helps to prevent condensation from forming. While they can be quite effective, it’s important to follow the manufacturer’s instructions carefully and to reapply as needed. Some products may require more frequent application than others.
Defogging Your Windshield Quickly
A fogged-up windshield is more than just annoying; it’s a serious safety hazard. Reduced visibility can make it difficult to see pedestrians, other vehicles, and road signs, increasing the risk of accidents. Luckily, there are several quick and effective methods to defog your windshield and get back on the road safely.
Using Your Car’s Defroster
Your car’s defroster is your first line of defense against a foggy windshield. Most vehicles have a front and rear defroster, usually indicated by a square icon with three wavy arrows pointing upwards. To use it effectively, turn on the defroster and set the temperature to hot. This directs warm, dry air onto the windshield, evaporating the condensation that causes fog. For quicker results, also turn on the air conditioning (A/C). While it may seem counterintuitive to use A/C in cold weather, it actually helps remove moisture from the air, speeding up the defogging process. If your car has a “recirculate” button, turn it off. This ensures that fresh, dry air from outside is being drawn in rather than recirculating the moist air inside the cabin.
Using a Defogging Product
While your car’s defroster is usually sufficient, a dedicated defogging product can offer extra help, especially in persistent or extreme conditions. These products often come in spray or wipe form and create a barrier on the windshield that prevents fog from forming. Apply the product according to the manufacturer’s instructions, usually by spraying it onto a clean microfiber cloth and wiping it evenly across the interior surface of the windshield. Be sure to choose a product specifically designed for automotive use and avoid household glass cleaners, as they may contain chemicals that could damage your windshield or leave streaks that impede visibility.
Opening Your Windows Slightly
This simple trick can be surprisingly effective, especially if the temperature difference between inside and outside your car isn’t too extreme. By cracking your windows slightly, you allow the moist air inside your vehicle to escape and be replaced by drier air from outside. This helps equalize the temperature and humidity levels, reducing the likelihood of condensation forming on your windshield. The amount you need to open your windows will depend on the weather conditions and the severity of the fog. Start by opening them just an inch or two and adjust as needed. However, keep in mind that this method may not be ideal in heavy rain or extremely cold weather. You can also try adjusting the airflow direction of your vents to point towards the side windows, assisting in the circulation of air and further reducing the fog build-up.
Here’s a quick overview of various approaches and their effectiveness:
| Method | Effectiveness | Speed | Notes |
|---|---|---|---|
| Car Defroster + A/C | High | Medium | Most common and reliable method |
| Defogging Product | Medium-High | Fast | Provides longer-lasting protection |
| Opening Windows | Medium | Slow | Best for mild fog and moderate temperatures |
| Running the AC | Medium | Medium | Helps dry out humid air inside the vehicle. |
| Using a damp cloth | Low | Slow | Temporary solution, might leave streaks |
Utilizing Your Vehicle’s Defrost System Effectively
Your car’s defrost system is your primary weapon against a foggy windshield. It works by directing warm, dry air onto the glass, evaporating the condensation that causes fog. However, using it effectively involves more than just flipping a switch. Let’s break down how to get the most out of your defroster.
Understanding the Science Behind Defogging
Fog forms on your windshield due to a temperature difference between the inside and outside air. When warm, moist air inside your car comes into contact with the cold windshield, the moisture condenses into tiny water droplets, creating that familiar hazy effect. The defroster combats this by heating the glass and lowering the humidity of the air blown onto it.
Activating Your Defrost System
Most vehicles have a dedicated button or dial for the front defroster, often symbolized by a windshield with three wavy arrows pointing upwards. Locate this control and activate it. You might also have a separate defroster for the rear window, usually indicated by a similar symbol with arrows pointing towards the back. Turn on both if needed.
Optimizing Airflow and Temperature
For quicker defogging, make sure your airflow is directed towards the windshield. Adjust the vents so that the air is blowing directly onto the glass. Set the temperature to warm or hot – cold air will only exacerbate the fogging. Additionally, turning on the air conditioning (A/C) can significantly help. Even if it seems counterintuitive to use A/C in cold weather, it dehumidifies the air, which is key to clearing the fog quickly. Experiment with different A/C settings to find what works best for your vehicle.
Fine-Tuning Your Defrosting Strategy
While the basic steps above will often suffice, here’s a deeper dive into maximizing your defroster’s efficiency. First, consider your vehicle’s recirculation setting. This control, often denoted by an icon of a car with a curved arrow inside, determines whether the system pulls in fresh air from outside or recirculates the air already inside. Initially, using fresh air is beneficial as it brings in drier air. However, once the windshield starts clearing, switching to recirculation can help maintain a comfortable temperature inside while preventing new moisture from entering. Next, patience is key. Depending on the severity of the fog and the outside temperature, it can take a few minutes for the defroster to completely clear the windshield. Resist the urge to wipe the glass with your hand or a cloth while it’s still fogged, as this can smear the condensation and make visibility worse. Instead, use the wipers once the glass is mostly clear. Finally, preventative measures can save you time and hassle in the long run. Keeping the inside of your windshield clean helps prevent fog from forming easily. Regularly wipe it down with a glass cleaner designed for automotive use. Park your car in a garage or covered area whenever possible, as this helps to minimize the temperature difference that causes fog. And, perhaps surprisingly, even something as simple as placing a dehumidifying product like a silica gel packet on your dashboard can absorb excess moisture and help prevent fog buildup. Below is a quick reference table for optimizing your defrosting strategy:
| Setting | Action | Reason |
|---|---|---|
| Temperature | Warm/Hot | Heats the windshield and promotes evaporation. |
| Airflow | Directed at windshield | Concentrates warm, dry air on the fogged area. |
| A/C | On | Dehumidifies the air, preventing further condensation. |
| Recirculation | Initially off, then on once clear | Starts with dry outside air, then maintains comfortable temperature. |
Improving Air Circulation Inside Your Car
Foggy windshields are a nuisance, reducing visibility and making driving dangerous. One of the most effective ways to combat fog is to improve the air circulation inside your vehicle. This helps balance the temperature and humidity levels, preventing condensation from forming on your windshield.
Use Your Car’s Ventilation System
Your car’s ventilation system is your best friend in the fight against fog. Make sure you’re using it correctly. Don’t just recirculate the air inside the cabin, as this trapped air is often already saturated with moisture. Instead, draw in fresh, dry air from outside.
Understanding Airflow Settings
Most cars have several airflow settings. Experiment with them to find what works best. The “fresh air” setting, often symbolized by a car with an arrow pointing inwards, pulls in outside air. The “recirculate” setting, usually symbolized by a car with a circular arrow inside, uses the air already within the cabin. For defogging, the “fresh air” setting is your go-to. You’ll also want to select the “defrost” setting, which directs airflow specifically towards the windshield.
Open Your Windows (Slightly)
This might seem counterintuitive, especially on a cold or rainy day, but even cracking your windows open a tiny bit can make a big difference. This creates a small exchange of air, helping to equalize the temperature and humidity inside and outside the car. Even a half-inch gap can significantly improve air circulation and reduce fogging.
Turn on the Air Conditioner (Even in Winter)
Many people associate AC with cooling down, but it also serves as a dehumidifier. AC units remove moisture from the air, which is key to preventing fog. So, even on a chilly winter morning, turning on the AC, even at a low setting, can help clear your windshield quickly. The dry air produced by the AC is excellent at combating condensation. Just be sure to use the “fresh air” setting along with the AC for optimal results.
Run the Front and Rear Defrosters
Using both the front and rear defrosters creates a two-pronged attack against fog. While the front defroster tackles the windshield, the rear defroster helps to reduce overall humidity in the car’s cabin. This combined effort leads to a quicker and more efficient defogging process. It’s like having a double-team of dryness working for you! Most cars also automatically engage the AC compressor when the defroster is on, further aiding in moisture removal. Don’t be afraid to crank up the fan speed on both defrosters to maximize their effectiveness.
Consider a Windshield Defogger
A dedicated windshield defogger can be a worthwhile investment, especially if you live in an area prone to fog or high humidity. These devices work by directing a stream of warm, dry air directly onto the windshield. They come in various forms, from small, portable units that plug into your car’s 12V outlet to more powerful models that integrate with your vehicle’s HVAC system.
Types of Defoggers and Their Benefits
| Defogger Type | Benefits | Considerations |
|---|---|---|
| 12V Portable | Compact, easy to use, affordable. | May not be as powerful as integrated models. |
| Integrated HVAC | More powerful, often integrated with climate control system. | More expensive, requires professional installation. |
| Chemical Defogging Sprays | Easy application, prevents future fogging. | Requires reapplication, some sprays may leave residue. |
Choosing the right defogger depends on your individual needs and budget. Portable 12V units are a good option for occasional use, while integrated models offer a more permanent and powerful solution. Chemical defogging sprays can also be effective as a preventative measure. They create a barrier on the windshield that repels moisture, but they do require reapplication periodically. Remember to follow the manufacturer’s instructions for any defogger you choose.
Using Anti-Fog Products and Treatments
Dealing with a foggy windshield is a common annoyance, especially during colder months or humid weather. Luckily, there’s a range of anti-fog products and treatments available to help maintain clear visibility and keep you safe on the road. These products work by creating a thin, transparent layer that prevents condensation from forming those pesky water droplets that obstruct your view.
Anti-Fog Sprays and Liquids
Anti-fog sprays and liquids are a quick and easy solution. Simply spray the product onto your clean, dry windshield and wipe it evenly with a microfiber cloth. This creates a barrier that repels moisture and keeps the glass clear. The effect typically lasts for a few days, depending on the product and weather conditions. Reapply as needed for optimal performance.
Anti-Fog Wipes
Pre-moistened anti-fog wipes offer a convenient and portable option. These single-use wipes are individually packaged, making them ideal for keeping in your glove compartment or car door pocket. Just like the sprays, wipe the product across your clean, dry windshield to create a fog-resistant barrier. While wipes might be slightly more expensive per application than sprays, their portability and ease of use make them a popular choice.
Anti-Fog Films
For a more long-term solution, consider applying an anti-fog film to your windshield. These films are thin, transparent sheets that adhere to the glass, providing a lasting anti-fogging effect. Installation requires careful cleaning of the windshield and precise application to avoid bubbles or wrinkles. While the initial application can be a bit more involved, anti-fog films offer extended protection and can last for several months or even years.
Hydrophilic Coatings
Hydrophilic coatings, sometimes called “water-loving” coatings, work differently than other anti-fog products. Instead of repelling water, they attract and spread it into a thin, uniform layer. This prevents the formation of larger water droplets that cause fogging. These coatings are often applied professionally and can provide long-lasting protection. They can also improve visibility in rainy conditions by helping water sheet off the windshield more effectively.
DIY Anti-Fog Solutions
Several household items can be used to create temporary anti-fog solutions. Shaving cream, applied thinly and buffed off, can leave a residue that helps prevent fogging. Similarly, a mixture of vinegar and water can have a similar effect. While these DIY methods may not be as effective or long-lasting as commercial products, they can be a helpful short-term fix in a pinch. Experiment to find what works best for you, and always test any DIY solution on a small, inconspicuous area of the windshield first.
Comparison of Different Anti-Fog Methods
To help you choose the best anti-fog solution for your needs, consider the following table comparing the different methods discussed:
| Method | Duration | Cost | Ease of Use |
|---|---|---|---|
| Anti-Fog Sprays/Liquids | Few Days | Moderate | Easy |
| Anti-Fog Wipes | Single Use | Moderate to High | Very Easy |
| Anti-Fog Films | Months/Years | High | Moderate (Installation) |
| Hydrophilic Coatings | Long-lasting | High (Professional Application) | Easy (After Application) |
| DIY Solutions | Short-term | Low | Variable |
Maintaining Your Windshield for Optimal Anti-Fog Performance
Regardless of the anti-fog method you choose, maintaining a clean windshield is essential for optimal performance. Regularly cleaning your windshield inside and out will remove dirt, dust, and grime that can interfere with the effectiveness of anti-fog products. Use a quality glass cleaner and a microfiber cloth to avoid streaks and scratches. A clean windshield provides a smooth surface for anti-fog products to adhere to, ensuring a clearer view and safer driving experience. Consider using a dedicated car interior cleaner to remove any residue from previous anti-fog products before applying a new one for best results.
Home Remedies for Windshield Fogging
Foggy windshields are a nuisance, obstructing visibility and creating a safety hazard. Thankfully, several readily available household items can effectively combat this problem. These simple solutions can save you money and time compared to commercial defoggers.
Shaving Cream
Believe it or not, shaving cream isn’t just for your face! It contains many of the same ingredients as commercial defoggers. Apply a small amount of shaving cream (any kind works) to the inside of your windshield. Rub it in thoroughly with a clean cloth, ensuring even coverage. Then, buff the windshield until it’s clear. This leaves behind a thin, invisible layer that prevents condensation from forming, keeping your windshield fog-free for a surprisingly long time.
Vinegar Solution
A mixture of vinegar and water is another effective home remedy. Mix equal parts white vinegar and water in a spray bottle. Spray the solution onto your windshield and wipe it clean with a soft cloth. The vinegar helps to break down the surface tension of the water, preventing those pesky water droplets from clinging together and forming fog. This solution is cheap, readily available, and leaves no streaks.
Alcohol and Water Mixture
Similar to the vinegar solution, rubbing alcohol mixed with water can also prevent fogging. In a spray bottle, combine one part rubbing alcohol with three parts water. Spray this mixture onto your windshield and wipe it dry. The alcohol evaporates quickly, preventing moisture buildup and keeping your windshield clear. Be sure to use isopropyl alcohol (rubbing alcohol) and not another type of alcohol.
Cat Litter
While it may sound strange, cat litter is excellent at absorbing moisture. Place some silica gel cat litter in a sock or a small, breathable bag. Place this in your car, preferably on the dashboard. The litter will absorb excess moisture from the air, reducing humidity inside your vehicle and minimizing the chance of fog forming on your windshield. This is a great preventative measure, especially in humid climates.
Salt
Similar to cat litter, salt acts as a desiccant, drawing moisture from the air. Fill a small sock or breathable bag with regular table salt and place it on the dashboard. This will absorb some of the moisture inside the car and help prevent fog formation. Be sure the container is sealed well to prevent salt spillage.
Open Windows (Slightly)
Sometimes, the simplest solution is the best. If weather conditions permit, cracking your windows open slightly can equalize the temperature inside and outside your car, reducing the likelihood of condensation and fogging. This allows for air circulation and helps to balance the humidity levels. Obviously, this isn’t ideal in heavy rain or extremely cold temperatures.
Preventing Future Fog: Maintaining a Dry Interior
Preventing windshield fog is often easier than clearing it once it forms. One of the most effective ways to combat fog is by keeping the interior of your car as dry as possible. Here are some proactive measures you can take:
Use Floor Mats: Especially during rainy or snowy weather, floor mats are essential. They trap water and moisture from your shoes, preventing it from evaporating into the air inside your car. Choose absorbent mats designed to hold moisture effectively. Regularly clean and dry your floor mats to maximize their effectiveness.
Remove Wet Items: Don’t leave damp items like umbrellas, jackets, or gym bags inside your car. They release moisture into the air, contributing significantly to fogging. Shake off excess water from umbrellas before storing them, and hang wet clothes to dry as soon as you get home.
Run the AC or Defroster: While you may be tempted to use the heater on a cold day, the AC or defroster are much more effective at clearing and preventing fog. The air conditioning system dehumidifies the air, removing the moisture that causes fog. In colder weather, the defroster directs dry, warm air onto the windshield, effectively evaporating the condensation. Experiment to find the optimal setting for your vehicle’s climate control system.
Regularly Clean Your Windshield: A clean windshield is less prone to fogging. Dirt, dust, and grime can provide a surface for water droplets to cling to, exacerbating fog formation. Clean your windshield regularly, both inside and out, using a quality glass cleaner. Avoid using ammonia-based cleaners as they can damage some window tints.
Pro-Tips for Keeping Your Windshield Fog-Free:
| Tip | Benefit |

| Keep a microfiber cloth in your car specifically for wiping the windshield. | Microfiber cloths are highly absorbent and leave a streak-free finish. |
| Park your car in a garage or covered area whenever possible. | This helps to minimize temperature fluctuations and reduce moisture buildup. |
| Consider a commercial defogging product if home remedies aren’t sufficient. | Many effective commercial products are available that provide long-lasting fog protection. |
By understanding the causes of fogging and taking these simple steps, you can ensure a clear view while driving, enhancing both your comfort and safety on the road.
Preventing Fog in Extreme Weather Conditions
Extreme weather, whether it’s freezing cold or sweltering heat, can make windshield fog a real nuisance. But with a few proactive measures, you can keep your visibility clear and stay safe on the road, no matter the conditions.
Extreme Cold
In frigid temperatures, the warm, moist air from your breath inside the car contrasts sharply with the icy windshield, causing condensation and fog. Here’s how to combat it:
Pre-Heating and Defrosting
Start your car’s defroster a few minutes before you plan to drive. Set it to defrost mode (usually symbolized by a windshield with an arrow pointing upwards) and direct the airflow towards the windshield. Select a setting that pulls in outside air, rather than recirculating the air inside the car. This will help equalize the temperature difference. A little patience here goes a long way.
Temperature Control
Adjust your car’s temperature to a comfortable but not excessively warm setting. This helps minimize the temperature difference between inside and outside, reducing the likelihood of fog formation. While it might be tempting to crank up the heat, a moderate setting is more effective in the long run.

Moisture inside your car is a major contributor to fog. Use floor mats to trap snow and water, and consider keeping a small towel handy to wipe up excess moisture. Parking your car in a garage, if possible, can also help keep it dry.
Extreme Heat and Humidity
High humidity can also cause fog, especially when you transition from a cool, air-conditioned car to the hot, humid outdoors. This type of fog forms on the *outside* of your windshield.
Air Conditioning
Just like in cold weather, air conditioning is your friend in humid conditions. Direct the cool air towards the windshield to quickly lower its temperature and dissipate the fog. Similar to defrosting in cold weather, pulling in outside air rather than recirculating can help.
Windshield Wipers
If the fog is light, your windshield wipers can help clear it away. However, for heavier fog, you might need to combine this with the air conditioning.
Dehumidifying Products
Consider using a dehumidifying product inside your car to absorb excess moisture. These products can range from small silica gel packets to rechargeable dehumidifiers. These are particularly helpful if you live in a consistently humid climate. Placing them under the seats or in the glove compartment can make a noticeable difference.
Crack a Window (With Caution!)
If safe to do so, cracking a window can help equalize the temperature and humidity inside and outside the car, reducing the chance of fog forming. Obviously, use caution when doing this, especially if driving in traffic or in areas with high crime.
Anti-Fog Products: Your Best Friend
Anti-fog products are specifically designed to prevent condensation from forming on your windshield. These products come in various forms, including sprays, wipes, and pastes. They create a thin, invisible layer that repels moisture. Apply these to a clean, dry windshield for optimal effectiveness.
| Product Type | Application | Longevity |
|---|---|---|
| Spray | Spray directly onto the windshield and wipe with a clean microfiber cloth. | Varies depending on the product, typically a few days to a week. |
| Wipes | Wipe the pre-moistened wipe across the windshield. | Generally shorter than sprays, often lasting a day or two. |
| Paste/Cream | Apply a small amount to the windshield and buff with a clean cloth. | Can offer longer-lasting protection, sometimes up to several weeks. |
Remember to always follow the manufacturer’s instructions for any anti-fog product you use. By taking these steps, you can ensure a clear view and a safer driving experience, regardless of the weather.
Preventing Windshield Fog
Windshield fogging occurs when the temperature of the glass is lower than the dew point of the surrounding air. Moisture in the air condenses on the cool surface, forming tiny droplets that obscure visibility. Effectively preventing fog requires manipulating the temperature and humidity inside the vehicle. Several methods can achieve this, ranging from adjusting the climate control system to utilizing specialized products.
One primary strategy involves using the defroster. Setting the climate control to defrost mode directs dry, heated air onto the windshield, quickly evaporating the condensation. For optimal results, ensure the air conditioning is activated, even in cold weather, as this dehumidifies the air further. Activating the recirculation function can initially speed up the defogging process by focusing the dry air within the cabin, but should be switched off once the fog clears to introduce fresh air.
Preventive measures can also be taken. Keeping the inside of the windshield clean helps prevent moisture from clinging to the surface. Commercial anti-fog products can create a barrier that inhibits condensation. These products often come in spray or wipe form and can be applied to the interior surface of the windshield.
Finally, managing the humidity inside the car is crucial. Avoid bringing excessively wet items into the vehicle, and ensure that floor mats are dry. In humid climates, using a desiccant product inside the car can help absorb excess moisture.
