What methods can be used to remove engine oil?

[Clarisse]

Engine oil can be treated using four methods: alcohol, olefin materials and turpentine, using oil to remove oil, and essential balm. The details are as follows: 1. Alcohol: Engine oil is a mixture of several alkanes and is an organic substance. According to the principle of "like dissolves like," organic substances can be used to dissolve engine oil, but it is best to choose an organic substance that is also soluble in water to avoid secondary pollution. The most convenient option is alcohol, which can dissolve in both organic solvents and water. The higher the alcohol concentration, the better, with anhydrous alcohol being the best. 2. Olefin materials and turpentine: For engine oil stains on clothes, you can first use gasoline to wipe them. If the stains are too heavy, olefin materials and turpentine can be used. After the stains dissolve, wash them with regular detergent. For stains on the collar, use a piece of absorbent cotton no smaller than a cigarette box soaked in gasoline and gently pat from the center of the collar outward. Do not use too little gasoline, as it may not remove the dirt and could leave gasoline stains. 3. Using oil to remove oil: If the stain is oily and does not absorb water, use "oil to remove oil"—wipe with a soft cloth or cotton dipped in gasoline to dissolve the oily color substance into the gasoline, then transfer it to the cloth. If gasoline cannot dissolve the stain, use chemicals with stronger oil-dissolving capabilities, such as benzene, chloroform, or carbon tetrachloride. For oil stains, sprinkle some raw flour on the stained area and brush with a palm fiber brush until the stain is removed. Then, use a rattan stick to beat the area and remove excess flour, making the fabric fluffy and clean. For oil stains on ski jackets, mix a small amount of flour with cold water to form a paste, apply it to the stain, and after a few hours, brush off the powder with water to remove the stain. 4. Essential balm: For small amounts of oil, using essential balm makes cleaning easy. Even stubborn oil stains can be removed.
