1. Blot up the diesel fuel immediately. Don't rub it, as this can spread the stain. Use a clean, absorbent cloth to blot up as much of the diesel fuel as possible.
2. Apply a degreaser to the stain. You can use a commercial degreaser or make your own by mixing equal parts dish soap and water. Apply the degreaser to the stain and rub it in gently with a soft cloth.
3. Rinse the shoes with water. Rinse the shoes thoroughly with clean water to remove the degreaser.
4. Dry the shoes. Allow the shoes to dry completely before wearing them again.
If the diesel fuel stain persists, you may need to take the shoes to a professional leather cleaner.
Here are some additional tips for removing diesel fuel stains from leather shoes:
* Act quickly. The sooner you start treating the stain, the more likely you are to remove it completely.
* Test the cleaning solution on a small area of the shoe before applying it to the entire stain. This will help you to ensure that the solution doesn't damage the leather.
* Don't rub the stain. Rubbing can spread the stain and make it more difficult to remove.
* Be patient. Removing a diesel fuel stain may take some time and effort.
