How to Remove Oil Film on the Car?

Sprinkle a little flour to absorb the oil before wiping it off. Wipe directly with a towel, and it will be cleaned immediately. Cover the windshield with toilet paper or tissue, then spray with car cleaner.

I remember last summer when driving, the front windshield always felt foggy, and later I found out it was due to oil film. I tried several methods myself: first, thoroughly rinsing the glass with car wash soap, then focusing on using white vinegar diluted with water (the kind used in kitchens), scrubbing hard with newspaper dipped in the solution. Vinegar is particularly effective at dissolving oil stains. For especially stubborn cases, I bought a specialized oil film removal paste online and used it with a sponge to grind in circular motions. Prevention is also simple—just clean the wiper blades every time you wash the car and avoid parking in areas with heavy oil smoke. The key is regular maintenance; otherwise, driving in the rain with blurred vision can be very dangerous. I check it monthly now.

I just finished removing the oil film from my car last month, so let me share my steps. First, prepare the tools: oil film remover, two clean towels, and a small spray bottle. The steps are simple: park the car in the shade, spray the glass with water, then apply the cleaner and scrub in circular motions with a wet towel. Focus on the lower half of the glass, where the oil film is thickest. After scrubbing, don’t rinse immediately—let the cleaner sit for 5 minutes to break down the grease before washing it off with clean water. Finally, dry and polish the glass with a clean towel. Remember not to use regular glass cleaner; choose a neutral pH cleaner. Also, avoid parking near restaurant exhaust vents, as oil films are caused by accumulated grease and exhaust fumes.

I'm particularly annoyed by the oil film issue, especially during the rainy season when it's hard to see the rearview mirror. I found that using toothpaste works quite well, just regular white toothpaste. Wet the glass, squeeze out a tube of toothpaste, and use a damp sponge to scrub the entire glass in circular motions. Spend a few extra minutes on areas with heavy oil film buildup. Then rinse with clean water, and the glass will immediately become crystal clear. The cost is less than two yuan, which is more cost-effective than buying specialized cleaners. There's also a trick to prevent oil film buildup in daily life: wipe the windshield every time you refuel, as gas stations usually provide free glass cleaner. If you make it a habit, you won't need specialized oil film removal for half a year.

My experience is that dealing with oil film requires different approaches depending on the severity. For mild oil film, simply mix dish soap with water in a 1:3 ratio in a spray bottle, spray it all over the windshield, and run the wipers for two minutes before rinsing it off immediately. For moderate cases, I recommend using an oil film remover—spray it on, wait three minutes, and then wipe. For severe oil film, a polishing compound is needed, but don’t apply too much pressure to avoid damaging the glass. For prevention, don’t neglect wiper maintenance, as worn rubber blades can leave oil marks. Also, wash your car promptly after highway driving, as bug splatter and tar are major contributors to oil film. After following these steps, I no longer experience glare when driving at night.

I'm most afraid of oil film during long-distance driving; once I almost had an accident on a rainy day. Later, I figured out a combination method: first, use kitchen paper towels soaked in baking soda water to cover the oil film area for five minutes to neutralize the grease. Then, use a dedicated automotive glass degreaser for thorough cleaning—this type of cleaner containing surfactants can break down oil molecules. For stubborn stains, gently scrub with a nano sponge. Finally, it's crucial to maintain the wiper blades, switching to beam blades to reduce friction marks. There's also a clever trick to prevent oil film: applying glass coating to form an oleophobic layer, so raindrops roll off directly, making it worry-free and safe.
