Tips to Reduce Window Condensation: Window condensation is what happens when the temperature and humidity inside your vehicle are different than it is on the outside. This difference causes the water droplets to collect on the glass, fogging up your windshield and severely limiting your visibility.
It can be challenging to effectively remove condensation once it’s already on your windshield, but we’re here to give you our top tips on getting your windshield de-fogged and road-ready.
Tip #1: Turn on Defrost
You’ve probably used this little button to melt windshield frost, but it’s also great for removing window condensation. Defrost, an A/C function found in most vehicles, targets warm air at the front and back windshields, making the fog go away. It’s also best to turn the temperature as high as it can and turn off the recirculation function to increase temperature and decrease humidity. Within minutes, your window will start to clear up!
Tip #2: Clean Your Windows
A dirty window can attract moisture, giving the water particles in the air a place to attach and settle. Cleaning your windows regularly, even if they don’t appear to need it, can prevent fogging.
However, if you’re driving and the fog comes on suddenly, keep a clean towel nearby so you can wipe away a section in order to see the road. This isn’t generally recommended, as it can have streaks on your glass, but if you’re in a situation where you can’t stop, and you can’t defrost, it’s better than using your hand, a dirty tissue, or any other fabric that might be available within your reach.
Tip #3: Use Windshield Wipers
Windshield wipers can indeed be a valuable tool when dealing with window condensation, especially when the condensation accumulates on the outside of the glass. If you find that your efforts to address condensation inside the vehicle aren’t yielding results, turning on your windshield wipers can be an effective solution. Here’s how it works:
When you activate your windshield wipers, they will sweep across the glass surface, collecting and wiping away the condensation. This action can provide temporary relief from impaired visibility caused by the moisture buildup. However, it’s important to note that this method may be most effective when your vehicle’s interior is still relatively cold.
In some cases, you may need to keep your wipers running until the glass warms up, allowing the condensation to evaporate or be dispersed more effectively. This technique can be particularly useful for your rear windshield, where condensation often tends to collect without clear lines of sight.
While windshield wipers are a practical solution for addressing exterior condensation, it’s essential to continue practicing preventive measures to minimize condensation buildup on both the inside and outside of your windows. Regular maintenance, proper ventilation, and addressing any potential issues with your vehicle’s seals can all contribute to a more comfortable and safe driving experience, especially during adverse weather conditions.
Tip #4: Dehumidify Your Vehicle
If nothing seems to be helping and your windshield continues to fog up persistently, it might indicate a more significant issue with your vehicle. While there are various products available in the market designed to de-fog windshields, such as dehumidifier mats and window treatments, ongoing problems should prompt you to investigate the root cause.
In the realm of automotive design, modern cars are engineered to create a tight seal against the external environment. This means that the newer your vehicle is, the more effective it should be at keeping out humidity and preventing condensation issues. However, if window condensation becomes a recurring problem, it’s advisable to seek professional assessment. There’s a possibility that the seals along your car’s windows and doors may have gaps or wear, allowing moisture to infiltrate the interior.
