What to Use to Wipe Car Windows to Prevent Fogging?

[ChloeAnn]

Car windows wiped with dishwashing liquid or soapy water are less likely to fog up because soapy water and dishwashing liquid contain surfactants that effectively prevent water vapor from condensing on the glass surface, thus serving an anti-fogging purpose. Mix dishwashing liquid and water in a ratio of approximately 1:10, then use a soft cloth to apply the prepared solution to the inner side of the front and rear windows. Alternatively, rubbing soap on a damp cloth and then wiping the glass can also prevent fogging. When dishwashing liquid or soap molecules enter the water, their polar hydrophilic parts disrupt the attraction between water molecules, reducing the surface tension of the water. This allows water molecules to spread evenly on the treated glass surface, forming a water film that adheres to the glass. The more rainwater hits the glass, the larger the water film becomes, maintaining the glass at an extremely high level of clarity.

I use a homemade solution of dish soap and water to clean car windows, with a ratio of one part dish soap to ten parts water. Spray it on a soft cloth and evenly apply it to both the inside and outside of the glass. Once dry, it forms a protective layer that prevents fogging. Clean once a week. In summer, avoid setting the air conditioning too cold to reduce temperature differences, and in winter, slightly open the windows for ventilation to reduce humidity more effectively. When parking, leave the windows slightly open to minimize moisture buildup inside—it's both cost-effective and safe. I learned this trick from a neighbor and also used it when my son was learning to drive, and the visibility improved significantly.

As a car enthusiast, I recommend specialized anti-fog sprays like Rain-X - apply and buff with a dry cloth for long-lasting effect. Before driving, use warm air to blow the windshield or activate the defrost function to preheat, maintaining stable cabin temperature. Regular cleaning is essential, avoid oil-based cleaners which worsen fogging. Car club experience suggests cracking windows slightly to reduce temperature difference, check sealing strips to prevent drafts, ensuring clear visibility for every trip and safer night driving.

I often encounter fogging issues while driving, especially on rainy days, which is quite annoying. Buying anti-fog wipes from the supermarket to wipe the windows can last for a few days. Turning off the internal circulation and letting the air conditioner absorb moisture is effective. In winter, I first turn on the warm air to blow the windows before setting off and gently wipe them with a clean cloth to reduce irritation. Through trial and error during my novice period, I found these methods, and now my vision is always clear, which makes me feel much better.
