How to Deal with Oily Windshield?

[MacAriana]

You need to purchase a professional windshield oil film remover online. After purchasing, first clean the windshield thoroughly. Remove dust and small particles, then pour some clean water on the windshield. Use the oil film remover and a clean damp towel to wipe back and forth. Continue wiping until there is no oiliness or oil mist. Then rinse off the foam with clean water and dry the windshield to completely remove the oiliness and oil mist. If you don't want to clean it yourself, you can take your car to a professional auto detailing shop for cleaning.

I find that oil stains on the windshield are quite common, and you'll inevitably encounter them after driving for a while. The simplest solution is to mix a little dish soap or detergent with water and gently scrub the oily area with a soft cloth or sponge. Remember not to use rough materials like old towels or steel wool, as they can scratch the glass surface. After scrubbing, rinse thoroughly with water to prevent residue from reflecting light and affecting visibility. Oil stains mostly come from road moisture, exhaust from vehicles ahead, or industrial area air, especially accumulating more easily on rainy days. So for prevention, I often keep the glass clean and avoid parking in heavily polluted areas. Using automotive-specific glass cleaner with a bit of degreasing function also helps, making daily driving much more worry-free. Safety comes first—oil stains can cause glare from headlights at night, increasing the risk of accidents, so they should be dealt with promptly once noticed.

As an experienced driver with years of driving under my belt, I recommend tackling oil stains step by step. First, park the car in a shady area to avoid direct sunlight, which can make cleaning more difficult. Wet the glass with water, then evenly spray a professional automotive glass cleaner and let it sit for two minutes to allow the degreasing agents to take effect. After that, use a soft sponge to wipe in circular motions. Make sure to dry the glass completely after cleaning, as any residue can attract dust. Oil stains mainly come from vehicle emissions or accumulated road grime, which can reduce wiper efficiency, so I regularly check the condition of the glass and clean it once a month. During daily driving, try to avoid following large trucks to minimize exposure to oil stains. You can also opt for wiper fluid with degreasing formulas to enhance maintenance. In terms of safety, oil stains can blur visibility, especially in rainy or snowy conditions, making it particularly hazardous. Don’t delay—address any issues as soon as they arise.

Oil stains obstructing the view must be handled with care. I usually mix warm water and white vinegar in a roughly 1:1 ratio, spray it on the glass, and let it sit for a while to break down the oil. Then, I gently wipe the entire surface with a soft cloth to avoid leaving scratches. After cleaning, rinse with clean water to ensure thorough removal, and finally dry with a clean towel. To prevent oil stains, which mostly come from airborne dust, I avoid parking near roadside restaurants where contamination is likely. I make it a habit to test the windshield wiper spray before heading out—if the issue is significant, I postpone driving. Driving safety is paramount; oil stains can blur vision, especially at night when glare is severe, so never overlook this issue.
