1. Clean the oil stains: clean the oil stains first and then carry out the subsequent cleaning. Do not use water to clean the oil stains after cleaning them all.
2. Toothpaste: Apply the mixture of detergent and toothpaste to the oily area, and then gently brush it after it penetrates into the shoes. After brushing, use a rag to remove the foam, and rinse it with water several times more.
3. Soap: chop up the soap and wash it with boiling water. Rub the shoes in soapy water and then clean them with clean water.
4. Shampoo: Shampoo has a good degreasing effect. You can squeeze a little shampoo to clean the greasy spots. The cleaning effect of shampoo is much better than that of detergent.
5. Gasoline: You can also use gasoline to smear on the oil stained areas. Gasoline has the function of removing oil stains. Although it has a strong smell, it can be cleaned by using detergent several times. Gasoline is flammable, so you can first use a small amount of gasoline to scrub. It should be noted that there should be no ignition sources around.
