Here are the methods to deal with diesel odor in the car trunk: 1. Ventilation and evaporation: Diesel has strong permeability, so open the car doors and trunk, and find a windy place to let it evaporate. 2. Charcoal deodorization: Diesel is a light petroleum product, a complex mixture of hydrocarbons, and serves as fuel for diesel engines. 3. Use vinegar to remove gasoline odor: Place a suitable container with water and vinegar in an appropriate position inside the car to effectively absorb methanol and eliminate gasoline odor. 4. Regular car washing: Regular and appropriate cleaning is also very helpful in removing odors.

Oh, I've been driving for over twenty years, and it's common for diesel to spill in the trunk. The smell is particularly pungent and stubborn. You need to deal with it immediately. First, use old towels or cat litter to absorb the oil—don't use regular cloth, as it can leak onto the carpet and make things worse. Then, wash it several times with dish soap water; diesel is highly oily and can easily seep into materials. Ventilation is crucial—leave the trunk open for a day or two to let the air circulate and speed up odor removal. For deodorizing, I usually sprinkle baking soda on the trunk floor overnight—it’s very effective at absorbing oil odors. Alternatively, you can place a few bags of activated charcoal, which you can buy cheaply at the supermarket. Safety reminder: Diesel fumes are harmful, so wear a mask and gloves when handling it, and avoid storing food in the trunk after cleaning to prevent poisoning. Always remember to tighten the fuel tank cap and add a leak-proof pad for prevention.
