How to Keep the Windshield Clear While Driving in the Rain?

You can choose to evenly apply soap or a water repellent on the car's windows to solve the problem. Here are the specific details: Soap: A wax layer will form on the glass surface, which has excellent water-repellent properties and can effectively prevent the glass from fogging up or water droplets causing blurred vision. Additionally, keeping a bar of soap in the car can also help freshen the air and eliminate odors. Water Repellent: Purchase and use a dedicated water repellent. Water repellents on the market generally come in two forms: spray and wipe-on. Evenly spray or apply the water repellent on the glass, and a protective film will form on the glass surface. This protective film also has excellent hydrophobic properties, effectively preventing the glass from fogging up or water droplets, ensuring clear visibility.
Driving in the rain is most frustrating with blurry windows. My approach is to tackle it layer by layer from outside to inside. Exterior rainwater relies on wipers—regularly replacing the rubber blades is crucial, as old and hardened ones leave streaks and squeak. Applying a hydrophobic coating to the glass is incredibly practical; it beads rainwater into droplets that roll away, offering significantly clearer visibility than untreated glass. For interior fogging, immediately turn on the AC for dehumidification—don’t fret over a bit of fuel, as cold air clears fog faster than warm air. Remember to activate the external air circulation to reduce cabin humidity quickly. Most cars have heated side mirrors—look for the button marked with a square icon containing wavy lines. At red lights, quickly wipe the interior glass with a dry cloth—far safer than doing it while driving. Also, monitor tire pressure; reduced traction in the rain makes maintaining standard pressure a safety must.
Poor visibility on rainy days is really nerve-wracking. Before every drive, I make sure to do three things: First, check if the windshield washer fluid is sufficient – tap water performs poorly and leaves streaks, while professional washer fluid can dissolve oily films. Next, inspect the windshield for any oily residue; a mixture of dish soap and toothpaste can serve as an emergency cleaning solution. If fogging occurs after setting off, don’t rush to wipe it – adjusting the AC temperature to around 22°C works best as smaller temperature differences reduce repeated fogging. Remember to activate the rear window defroster (many drivers don’t realize those horizontal lines are heating elements). When parking, adjust the AC vents to avoid blowing directly onto the windshield to prevent cracks from thermal expansion/contraction. In heavy rain, keep speed below 60 km/h and maintain at least two car lengths’ extra following distance for safety.
