How to deal with water droplets not being completely wiped off when rolling up the car window?

[StVera]

It is normal for water droplets not to be completely wiped off when rolling up the car window, as the window rolling mechanism itself does not have a wiper function. If the door seal strip is not tightly designed or has large gaps, it will not completely wipe off water droplets. Methods to deal with water droplets on the car window: 1. Install rain guards on the windows and rearview mirrors, which allow you to slightly lower the window on rainy days without rainwater entering the car; 2. Applying soap to the glass can improve visibility on rainy days; 3. Apply glass polish to a dry sponge and wipe the glass in a certain order. The car window is an important part of the entire vehicle body, designed to meet the needs of interior lighting, ventilation, and the visibility of the driver and passengers. According to the different installation positions of the glass, car windows can be divided into: front and rear windshields, side windows, and door windows.

Last time I drove in the rain, I also encountered the issue of water droplets sticking to the window when rolling it up. Later, I found out the window seal had aged. We can start by thoroughly cleaning the seal with a neutral cleaner—often, accumulated dust and oily films cause the seal to lose its elasticity. If it still leaks after cleaning, chances are you'll need to replace the seal. If you're doing it yourself, there are installation videos online for your specific car model, and aftermarket parts cost around 30 yuan. If you find it troublesome, a repair shop will handle it for about a hundred yuan including labor. Try not to park in direct sunlight to prevent the seal from hardening and deforming. After washing the car, remember to spray some window lubricant into the seal groove to extend its lifespan. If the window struggles to roll up or down, avoid forcing the switch to prevent motor burnout.

If the car window doesn't wipe water droplets clean, first check if the glass is clean. I often use dish soap mixed with water to clean the glass, focusing on removing the inner oil film. Nowadays, there are rain repellent products with hydrophobic coatings that can last two to three months per application. Inspect the rubber seals carefully, pulling them apart to check for cracks or deformations—aged seals will turn white at the edges. Dust buildup in the tracks can also affect window movement; cleaning them with a toothbrush dipped in soapy water works well. Once, my friend's window motor failed, causing misalignment during movement and poor wiping—this requires inspection on a lift. If water droplets cling to the window while driving in the rain, turning on the external air circulation can reduce fogging. I recommend cleaning the window tracks monthly; with proper maintenance, issues are unlikely to arise.

This issue is most likely caused by the sealing rubber strip. After three to five years of use, the rubber strip tends to harden and deform, especially under high summer temperatures which accelerate aging. You can first try applying a rubber conditioner to restore its elasticity—this might solve the problem. If that doesn't work, replacing the rubber strip is an option. For standard car models, an original replacement costs under 100 yuan, and you can do it yourself by simply removing the door panel screws. If the rubber strip is intact, check for hairline scratches on the window or clogged door drainage holes that might cause water accumulation. Avoid using a high-pressure water jet directly on the rubber strip seams during car washes, as this can easily deform them. I always keep a chamois cloth in my car—it's perfect for wiping off residual water droplets after rolling the windows up or down.

As an experienced driver, the first thing I check is the condition of the rubber seals. I run my fingers along the edges to feel for fraying or cracking, then observe if the window rolls up and down smoothly. Daily prevention is crucial: apply Vaseline weekly to moisturize the seals, and avoid parking under trees to prevent sap and insect residue corrosion. After rain, promptly wipe away water stains to prevent mineral deposits. The passenger side window is more prone to this issue because it's used less frequently, causing slower rubber deformation. Once I found sand particles in the window track causing the glass to tilt and not wipe cleanly - a quick vacuuming fixed it. Those with modified windows should be especially cautious, as aftermarket seals often have sizing issues.
