How to Deal with Fog on the Outside of the Car's Windshield?
3 Answers
To address fog on the outside of the car's windshield, you can follow these methods: 1. Turn on the car's heater and direct it towards the windshield to reduce the temperature difference between the inside and outside of the glass, preventing condensation and fogging; 2. Open a small gap in the window to allow air circulation, which helps remove moisture and balance the temperature inside and outside the car; 3. Apply a solution of dish soap, soapy water, or saltwater to the windshield and wipe it clean. The windshield is made by sandwiching two layers of glass with a layer of PVC plastic in between, creating a laminated glass structure similar to a sandwich. It is typically designed as a large, curved single-piece unit with specific curvatures on all sides, making both its manufacturing and installation processes highly technical.
Having driven for many years, I've learned the tricks to deal with fogging on the outside of the windshield. When faced with this issue, I first gently sweep it with the wipers—simple and effective. If the fog is too heavy, I immediately turn on the car's air conditioning, set the vents to windshield-only mode, and activate the defogging function. Using the external air circulation helps improve airflow and reduces condensation due to temperature differences. Fog on the outside often occurs when the interior is warm and the outside is cold, so cranking up the heater helps remove moisture. I also keep a bottle of anti-fog spray handy, applying it periodically to form a protective film that prevents fogging for several days. During regular maintenance, I make sure to clean the glass surface thoroughly to remove oil stains and dirt, minimizing the chance of buildup. In winter, if the wipers can't move freely, I avoid forcing them and instead find a safe spot to park and wipe the glass with a soft cloth to prevent damage. These methods keep my driving vision clear, ensuring safety and peace of mind.
I place great emphasis on driving safety, and it's crucial to immediately address fogging on the outside of the windshield. As soon as I notice fog forming on the exterior, my first action is to activate the wipers to try and clear it. If the effect is unsatisfactory, I turn on the car's heater and direct warm air at the glass for a few minutes. Fog on the outside is primarily caused by temperature differences—warm interior and cold exterior leading to condensation. Turning on the external air circulation can help balance the air and reduce the risk of condensation. Personally, I also prefer using an anti-fog cloth to gently wipe the glass, being careful to avoid scratches with light motions. Daily preventive measures are equally important: after washing the car, ensure the glass is free of residual grease, and apply anti-fog agents to maintain a dry surface. Before driving, always check the vehicle's condition, especially in cold weather, and preemptively turn on the air conditioning to defog. Improper handling can obstruct vision and lead to accidents, so it's essential to perform each step carefully from start to finish to ensure the safety of yourself and others.
