The Tesla windshield is an integral part of Tesla vehicles known for its advanced features and technologies. Tesla has incorporated several innovative aspects into their windshields to improve safety, visibility, and overall driving experience.
When it rains or snows, fog is likely to form on your Tesla windshield which affects visibility. You will need to know how best to quickly, safely, and effectively remove the fog to restore optimal visibility, and that’s what this article is all about.
How To Defog A Tesla Windshield
- Turn on the Climate Control: The first step is to turn on the climate control system in your Tesla. This can be done by accessing the climate control settings on the touchscreen display or using voice commands if your Tesla is equipped with that feature.
- Select the Defrost Mode: On the touchscreen, select the “Defrost” or “Defog” mode. This mode directs air to the windshield and side windows to clear condensation and fog. You may also need to adjust the fan speed to a moderate setting.
- Adjust the Temperature: Set the temperature to a comfortable level. Warm air can hold more moisture than cold air, so using warm air will help clear the condensation more quickly. However, you don’t need to make it extremely hot; a comfortable temperature should suffice.
- Recirculation Mode: Ensure that the climate control system is set to use outside air (the “fresh air” mode) rather than recirculating cabin air. Using fresh air helps reduce humidity inside the vehicle.
- Turn on the Rear Defroster: If your Tesla has a rear window defroster, activate it to clear any fog or condensation on the rear window. This can further improve visibility.
- Use Air Conditioning: In some cases, using the air conditioning (AC) can help remove moisture from the cabin air. You can turn on the AC in combination with the defrost mode to speed up the defogging process.
- Ventilation Settings: Ensure that the ventilation system is set to defrost the windshield and side windows. Most Tesla vehicles offer multiple ventilation settings, so make sure the airflow is directed toward the windshield.
- Adjust Fan Speed: If necessary, adjust the fan speed to a level that effectively clears the windshield without creating excessive noise or discomfort.
- Crack a Window: In situations of high humidity or moisture inside the vehicle, cracking a window slightly can help improve airflow and reduce condensation.
- Clean the windshield. If the windshield is dirty or greasy, it will be more likely to fog up. Use a glass cleaner to clean the inside and outside of the windshield.
- Patience: Give the climate control system some time to work. It may take a few minutes for the windshield to completely clear of fog or condensation, especially in very humid conditions.
Here are some additional tips to help prevent fog from forming on your Tesla windshield:
- Keep the inside of the car clean and dry. Wet floors and carpets can contribute to fogging.
- Avoid using the recirculation mode on the climate control system. The recirculation mode can trap moisture in the air, which can lead to fogging.
- Park in a well-ventilated area. If possible, park in a garage or under a carport. This will help to keep the inside of the car cool and dry.
Things to Note
By default, climate control is set to Auto, which maintains optimum comfort in all but the most severe weather conditions. When you adjust the cabin temperature while in the Auto setting, the system automatically adjusts the heating, air conditioning, air distribution, and fan speed to maintain the cabin at your selected temperature.

If you’re still having trouble clearing the fog, you can try using a commercial defogger. Be sure to follow the instructions on the defogger carefully.
Commercial Defoggers For Tesla
Here are some of the best commercial defoggers in the market today for Tesla windshields:
Rain-X offers an Anti-Fog treatment that can be applied to the interior of your Tesla’s windshield. It helps prevent fogging and improves visibility. It also removes smoke residue.
It’s great not only for Tesla windshields but for home usage on glass and mirrors as well as on marine glass.
What I love about this product is that it serves both to remove fog and to prevent fog from forming in the first place.
This product can be used to clean and defog the windshield. It is also a good choice for removing stubborn stains and water spots.
It is gentle, safe for your Tesla windshield, leaves no streaks, has no harsh chemicals, and protects against fog forming.
The Clarity Defender Anti-Fog Treatment is another option designed to prevent fogging on glass surfaces, including Tesla windshields. Here are some benefits:
- Repels rain at highway driving speeds for better vision and a reduced need for windshield wipers
- Bonds to glass and mirrors, creating a nanoseal that offers protection from road salt, windshield washer fluid and household cleaners
- Includes a convenient, disposable applicator and a high-quality microfiber buffing cloth
- Applies easily – wipe on, wipe off in 15 minutes – and lasts up to one year
- Makes a windshield easier to clean and reduces wear and tear of wiper blades
- Does not harm paint or trim
Clarity Defog It is another great option and has been used for over a decade by even law enforcement and emergency services. It is a treated microfibre cloth that you just apply on the windshield to remove the fog very easily.
This product’s nano-sized particles penetrate deep inside the windshield’s interior side and form a chemical bond, preventing fog buildup inside the vehicle. It is a suspension liquid made from Americal base oils, and is both safe and super-effective for your Tesla vehicle
There are other commercial defoggers out there. When choosing a commercial defogger for your Tesla windshield, it is important to consider the following factors:
- Safety: It must be safe for both you and your Tesla Windshield and its integrated components

Here are some additional tips for using defoggers effectively:
- As much as possible, apply the defogger to a clean and dry windshield. So, use a dry cloth to clean the windshield first before applying the defogger.
This will help to ensure that the defogger adheres properly and provides the best results.
- Follow the instructions on the defogger carefully. Some defoggers need to be applied in a specific way or for a certain amount of time in order to be effective.
- Reapply the defogger as needed. Defoggers typically need to be reapplied every few weeks or months, depending on the product and the climate you live in.
Importance Of Tesla Windshield For Proper Care
Your Tesla windshield is not just any windshield. Here are a few things to know about it so you handle it with care in terms of defogging, cleaning, and general maintenance:
- UV and Infrared Protection: Tesla windshields are designed to block a significant portion of harmful UV (ultraviolet) rays and infrared radiation, helping to protect passengers from sun-related skin damage and keeping the interior cooler.
- Laminated Glass: Tesla windshields are often made of laminated glass, which consists of multiple layers of glass with a polymer layer in between. This construction makes the windshield more durable and less prone to shattering upon impact.
- Acoustic Insulation: Tesla has designed its windshields to reduce noise from outside the vehicle, providing a quieter and more comfortable driving experience. This is achieved through acoustic laminated glass that dampens sound vibrations.
- Heated Wipers and Defroster: Tesla vehicles often come equipped with heated windshield wipers and a defroster system to quickly clear ice and snow in colder climates.
- Rain-Sensing Wipers: Tesla vehicles feature rain-sensing wipers that automatically adjust their speed based on the intensity of rainfall, improving visibility during wet conditions.
- Autopilot and Full Self-Driving (FSD) Features: Tesla’s advanced driver-assistance systems, such as Autopilot and Full Self-Driving, rely on cameras and sensors placed around the vehicle, including on the windshield. The windshield plays a crucial role in providing a clear view for these systems to operate effectively.
- HUD (Heads-Up Display) Potential: While not available in all Tesla models, some speculation has arisen about the potential for a heads-up display projected onto the windshield to provide the driver with important information without having to take their eyes off the road.
- Aerodynamics: Tesla designs its vehicles with aerodynamics in mind, and the shape and curvature of the windshield are carefully engineered to reduce wind resistance, which can contribute to better energy efficiency and longer electric range.
- Camera Housing: Tesla vehicles with advanced driver-assistance systems often have a housing for forward-facing cameras mounted near the rearview mirror, further enhancing the effectiveness of these systems
I have listed all these details about the Tesla windshields so that you know how important they are beyond just visibility and driver protection, and so that you appreciate the considerations made when choosing the right ways to properly defog the windshield without causing any damage to the windshield and the integrated components in the process.
