How to Deal with Foggy Side Mirrors on Rainy Days?
2 Answers
Before applying, slightly moistening the soap will make it softer and easier to spread on the glass surface. After installing rain guards, the phenomenon of water droplets on the side mirrors can indeed be alleviated to some extent, especially when driving in light rain. Apply car wax to the exterior mirrors using a sponge and then rinse it off with clean water. The protective layer of car wax can prevent rainwater from staying on the mirror surface. Crush a large amount of garlic and evenly apply the juice from the garlic onto the side mirrors. Areas treated with garlic will not have water droplets adhering to them.
Having driven for 30 years, I've encountered foggy rearview mirrors on rainy days quite often. I always check to ensure the mirrors are clean and dust-free before driving. If fogging occurs mid-drive, I immediately crack the window slightly to balance the temperature difference by allowing air circulation, or pull over safely to wipe them with a dry cloth. In winter, I frequently use the air conditioning's defogging mode, directing stronger airflow toward the rear windshield, which also clears the rearview mirrors. I usually keep some anti-fog spray handy—specifically designed for cars—applying it during car washes for temporary protection. Ultimately, developing good habits saves trouble and ensures peace of mind; don’t wait until the mirrors are completely obscured, making lane changes dangerous. Rainy roads are slippery with poor visibility—never force driving under such conditions.
