To remove the oil film on the inside of the car windshield, you can follow these steps: 1. Purchase a professional oil film remover for windshields online. After receiving the product, first clean the windshield thoroughly. 2. Mainly remove dust and small particles, then sprinkle some water on the windshield. Use the oil film remover and a clean, damp towel to wipe the glass back and forth. 3. Continue wiping until there is no oil film left, then rinse off the foam with clean water and dry the windshield to completely remove the oil film. 4. If you prefer not to clean it yourself, you can take your car to a professional auto detailing shop for cleaning.
I've seen this issue of oily fog on the inside of the windshield many times. It's usually caused by high humidity in the car mixing with oil residues from interior cleaners. The solution is to first try wiping it with a clean microfiber cloth. If that doesn't work, use diluted white vinegar water for effective and eco-friendly cleaning. After cleaning, make sure to thoroughly dry the surface to avoid moisture buildup causing secondary issues. It's recommended to regularly replace the cabin air filter to reduce moisture accumulation. Use fewer oily spray products like perfumes or leather waxes in the car to prevent oil film recurrence. Remember that oily fog scatters light at night, affecting visibility. If discovered, handle it immediately for safety - don't delay.
My car's windshield had oil film, so I fixed it myself with a simple DIY method: Prepare a mixture of water and white vinegar in equal parts, spray it on a soft cloth, and gently wipe the inner oil stains. They come off quickly. If you don't like the vinegar smell, you can replace it with a few drops of dish soap mixed with water, which is equally effective. After wiping, use another dry cloth to dry it to prevent fogging. For daily prevention, choose oil-free products when cleaning the interior. Avoid keeping the air conditioner on low settings all the time; direct the airflow toward the windshield to reduce condensation. For older cars, replace the air filter every six months—it saves money and avoids driving hazards, especially during rainy days when oil mist risks are higher.
