When vegetable oil is spilled in the trunk, remove the trunk mat and clean it with laundry detergent or a professional cleaning solution. After cleaning, expose it to direct sunlight to prevent odors in the trunk. Alternatively, you can drive the car to a car wash and ask the staff to clean it.

Last time I also spilled cooking oil in the trunk, and it was quite troublesome to clean up. First, find a thick towel to absorb the excess oil stains to prevent the oil from spreading. Then mix kitchen detergent with warm water at a ratio of about 1:10, and use a stiff-bristled brush dipped in the solution to scrub the oily area repeatedly. After scrubbing, wipe it twice with a damp cloth, otherwise the residual foam will become sticky. The key is to remove the trunk mat and let it dry in the sun for three days, as the mat's inner layers are most likely to trap oil odors. Finally, spray some liquor in the corners to disinfect and eliminate odors—it works much better than car air fresheners. If the oil seeps into the upholstery foam layer, you must use a foam cleaner for deep treatment, otherwise the smell will definitely come back in the summer heat.

To deal with cooking oil leaks, I have a set of effective methods. Immediately cover the oil with kitchen paper towels and absorb until the paper no longer becomes oily. Prepare a cleaning solution: baking soda + dish soap + white vinegar, and scrub back and forth with the rough side of a dish sponge to break down the grease. After cleaning, don't rush to close the trunk—leaving it open to dry in the sun for two days is crucial, as UV rays naturally eliminate odors. For residual oil film on plastic parts, use alcohol wipes to clean, and for fabric areas, steam with a garment steamer for five minutes. Remember, if oil stains stay on suede for more than two hours, they become difficult to remove, so act quickly upon discovering a leak. Always keep a bag of cat litter in the car for emergencies—it can serve as an oil absorbent.

The key to cleaning vegetable oil stains lies in two steps: degreasing and deodorizing. First, sprinkle flour or cornstarch on the oil stain to absorb the oil, let it sit for half an hour, then sweep it away. Next, mix hot water with half a capful of laundry detergent and use an old toothbrush to scrub the textured gaps carefully. The most challenging part is removing oil from rubber seals, which requires slowly wiping with a cotton swab dipped in essential balm. After cleaning, spread a layer of coffee grounds to absorb odors for two days; the coffee grounds can be dried and reused. If the oil contaminates the spare tire well, the spare tire must be removed, and the metal parts should be rinsed with a high-pressure water gun. Throughout the process, wear rubber gloves to protect your hands.
