What to Do When the Interior Windshield Cannot Be Cleaned Properly?

The solutions for an interior windshield that cannot be cleaned properly are: 1. Apply toothpaste on it, wet it with water, then wipe with a sponge or soft cloth, followed by a final wipe with glass cleaner; 2. First wipe with a damp cloth, then use a clean damp cloth dipped in some alcohol or liquor to scrub the car glass vigorously; 3. Try using a polishing machine with polishing compound to remove stubborn stains. During regular glass maintenance, choose the appropriate glass cleaner based on the season and weather conditions. When the windshield surface appears blurry, cleaning it with the right glass cleaner can make it much clearer. If you notice random reflections on the glass at night, you can also use glass cleaner to wipe it down.
When I drive my kids to school, I often notice the windshield gets greasy and hard to clean, which affects visibility. Over time, it also tends to fog up. The solution is simple: I mix white vinegar and water in a 1:1 ratio to make a cleaning spray, apply it, wait a few minutes, and then gently wipe with a microfiber cloth—it works great. Before wiping, I use a dry cloth to remove dust to avoid scratching the glass. On hot days, I avoid cleaning under direct sunlight to prevent streaks. Doing this weekly helps prevent dust buildup and fogging. Managing indoor humidity is also important—using the AC’s dehumidifier or placing desiccant packs on the dashboard can reduce fogging. Safe driving comes first.
I particularly enjoy DIY car maintenance, and for small tasks like cleaning windows, using professional tools is the most efficient approach. I recommend spraying automotive-specific glass cleaner onto the glass, then wiping it dry in circular motions with a microfiber cloth. Avoid using regular paper towels or newspapers to prevent leaving behind lint and streaks. Pay attention to wiping direction—move uniformly upward from one side to prevent water droplets from running back and forming streaks. After cleaning, inspect all corners, including areas near the rearview mirror, for any missed spots. Additionally, ensure proper ventilation by rolling down the windows for a few minutes to dissipate the cleaner's odor, improving in-cabin air quality. Regularly replacing the cabin air filter can also reduce dust dispersion and window contamination, keeping not just the glass clean but also enhancing overall comfort inside the vehicle.
After years of driving, I often encounter the problem of oily windshield stains, which are very dangerous in rainy weather or at night if not cleaned properly. The most straightforward method is to find clean water, wet a cloth, and gently wipe, or use an emergency cleaning spray to remove stains. Avoid using alcohol-based products to wipe, as they can dry out and crack the glass surface. Daily attention to opening windows for ventilation can reduce the accumulation of smoke and dust inside the car, and maintaining simple cleanliness can prevent blurred vision. Prevention is far better than repair, and safe driving requires attention to these small details.
I am very concerned about the environmental health inside the car. A dirty windshield not only affects visibility but also breeds bacteria, posing a risk to the respiratory system. For cleaning, using natural materials like a paste made from lemon juice and baking soda, applying it for a few minutes before wiping it off, works well. Ensure the glass is dry and then polish it with a soft cloth to remove any residue. Also, check the ventilation inside the car, using the air conditioning or fan to disperse odors and reduce irritation from chemical smells. Regular maintenance can prevent such issues, making travel more reassuring.
