What You'll Learn

Use a strong degreaser on the car mats
If you've spilled diesel fuel on your car mats, one way to get rid of the smell is to use a strong degreaser. This method may require multiple applications to be effective. First, get a bucket of warm water with soap or detergent. Soak the mats in the water for about 30 minutes. Then, scrub the mats with a clean cloth or a hard-bristled brush to remove any remaining dirt or residue. Rinse the mats thoroughly with tap water or a high-pressure hose.
Next, apply the degreaser to the mats. You may need to do this several times to eliminate the diesel smell. Finally, dry the mats in direct sunlight for at least three hours, ensuring there is airflow underneath them. If the mats still smell after this process, continue to let them sit in the sun until the odour disappears.

Wash the car mats with Listerine
If you're looking to remove the smell of diesel fuel from your car mats, one suggested method involves using Listerine, a common mouthwash. This method is also recommended for removing diesel odours from clothing, and it is said to be effective in eliminating almost any odour.
To start, you'll need to gather your supplies: a bottle of Listerine, rubber gloves, and a scrub brush or sponge. It is recommended to work in a well-ventilated area or even outdoors if possible, as the fumes from the diesel and Listerine can be strong. If the spill is recent and the car mats are heavily soaked, you may want to consider soaking up the excess diesel with paper towels before proceeding.
Once you're ready, pour a generous amount of Listerine directly onto the affected areas of the car mats. Ensure that you thoroughly saturate the mats to allow the Listerine to penetrate the fibres and neutralise the diesel odour. Use your scrub brush or sponge to work the Listerine into the mats, scrubbing vigorously to help loosen and break down any remaining diesel residue.
Let the mats sit for a while, allowing the Listerine to work its magic. You should begin to notice a reduction in the diesel odour. If needed, you can repeat the process, ensuring that you thoroughly scrub and treat the affected areas.
After you've finished treating the mats with Listerine, you can then use a carpet shampooer to wash the mats and remove any remaining traces of diesel and Listerine. Make sure to follow the instructions on your carpet shampooer and use a suitable cleaning solution. If you don't have access to a carpet shampooer, you can try using a wet-dry vacuum to extract as much of the moisture as possible, followed by a thorough scrub with a mild detergent and warm water.
By following these steps and using Listerine, you can effectively neutralise diesel odours and restore your car mats to a fresh and pleasant state.

Use a carpet shampooer
If you have access to a carpet shampooer, this can be an effective way to remove diesel odours from your car. This method is particularly useful if the diesel spill has occurred on the car's carpet or mats, as the shampooer will be able to penetrate the fibres and remove any traces of diesel.
To start, you may want to try rubbing some Listerine onto the affected area. Listerine is often used by firefighters to get rid of smoke smells from their clothing, so it can be effective in neutralizing strong odours. You can then use the carpet shampooer to wash the area clean. It is important to use a strong detergent or shampoo that is designed to remove grease and odours. If you are unsure, you can test the detergent on a small, inconspicuous area of the carpet first to ensure it does not cause any discolouration or damage.
When using the carpet shampooer, follow the manufacturer's instructions and allow the detergent or shampoo to soak into the carpet for the recommended amount of time. You may need to go over the affected area multiple times to ensure that all traces of diesel are removed. If the diesel smell persists, you can try using an odour neutralizer specifically designed for use with carpet shampooers, or sprinkle baking soda onto the carpet and let it sit for 15 minutes before vacuuming it up.
In addition to using a carpet shampooer, you can also try laying mothballs in your car. Mothballs are effective at neutralizing odours, but should only be used in well-ventilated areas or outside of the car if you have pets or children. You can also try using a citrus-scented laundry detergent, as the strong citrus smell can help to mask and neutralize the diesel odour.
It is important to note that diesel fumes can be toxic, so it is recommended to wear protective gear, such as gloves and a mask, when cleaning up any diesel spills and attempting to remove the odour from your car. Additionally, ensure that the area is well-ventilated during and after the cleaning process to help dissipate the diesel smell.

Lay mothballs in the car
Laying mothballs in your car can be an effective way to neutralise the smell of diesel. However, it is important to exercise caution, as the strong-smelling naphthalene or paradichlorobenzene in mothballs can be harmful to your health. If you have children or pets, it is recommended to avoid using mothballs altogether.
If you choose to use mothballs, open the windows of your car and allow ample ventilation during and after the process. You can place the mothballs in bowls or containers and leave them in the car for several hours or even a few days. The longer the mothballs remain in the car, the more effective they will be in absorbing and neutralising the diesel odour.
While mothballs can be effective, they may not completely eliminate the diesel smell, especially if the spill has occurred on soft goods like carpets, rugs, or upholstery. In such cases, you may need to combine the use of mothballs with other odour removal techniques.
Additionally, it is important to note that mothballs themselves have a strong and persistent odour. If you wish to avoid the long-lasting mothball smell, consider using alternative odour absorbers like charcoal or baking soda. Place these in bowls, similar to mothballs, and leave them in your car for a few days to absorb the diesel smell.

Use a citrus-smelling laundry detergent
If you're looking to remove the smell of diesel fuel from your car, one recommended method is to use a citrus-scented laundry detergent. This method is particularly useful if you've had a diesel spill on your car's floor or mats, as the detergent can help neutralise the odour.
To effectively use this method, follow these steps:
- Choose a citrus-smelling laundry detergent: Opt for a detergent with a strong, fresh citrus scent, such as lemon or orange. The detergent should be specifically designed for laundry, as regular dish soap or hand soap may not be as effective.
- Prepare the affected area: If the diesel spill is still fresh, use paper towels or a clean cloth to absorb as much of the liquid as possible. This will help reduce the intensity of the smell and prevent it from spreading further.
- Apply the detergent: Depending on the affected area, you can pour, spray, or rub the citrus-scented detergent directly onto the spill. If the spill is on the car's floor or mats, you may need to use a brush or sponge to work the detergent into the surface.
- Let it soak: Allow the detergent to sit on the affected area for several minutes. This will give it time to penetrate the surface and neutralise the diesel odour. Refer to the detergent's instructions for the recommended soaking time.
- Scrub or wipe the area: After soaking, use a brush or a clean cloth to scrub or wipe the area vigorously. This will help remove any remaining diesel residue and ensure that the citrus scent is thoroughly distributed.
- Rinse and dry: If possible, rinse the area with clean water to remove any detergent residue. This is especially important if you're cleaning car mats or carpets, as detergent residue can attract dirt. Finally, allow the area to air dry completely.
It is important to note that while a citrus-smelling laundry detergent can effectively neutralise diesel odours, it may not be sufficient for extremely strong or persistent smells. In such cases, you may need to combine this method with other odour-removal techniques, such as using baking soda, vinegar, or a commercial odour eliminator. Additionally, proper ventilation and time are also crucial factors in completely removing diesel smells from your car.
