What is the most effective method to remove oil stains?
2 Answers
Using alcohol washing, gasoline mixing, alkene material wiping, or baking soda soaking are the most effective methods to remove oil stains. Alcohol washing: Alcohol can act as a decolorizing agent and is easily soluble in water and organic solvents. Engine oil is a mixture of several alkanes, which are organic compounds soluble in alcohol. The higher the alcohol concentration, the better, with anhydrous alcohol being the most effective. Gasoline mixing: Gasoline can effectively remove oil stains, but excessive use should be avoided as it may leave additional gasoline stains. Alkene material wiping: For heavy oil stains, wiping with alkene materials can yield better results. Baking soda soaking: Baking soda can dissolve engine oil, and soaking with baking soda can help remove oil stains.
Don't panic when dealing with oil stains in daily life. My usual method is to first cover the stain with flour or talcum powder, rub it a couple of times to absorb the oil, then soak it in dish soap mixed with warm water for half an hour, and finally scrub it clean with an old toothbrush. This works well for both clothes and floors, and the materials are easy to find and safe to use. For stubborn stains, mix some baking soda into a paste, apply it for half an hour, and then scrub. Repeat this two or three times, and the stain will be mostly gone. It's more convenient than directly spraying chemicals and doesn't harm your hands. Remember to wear rubber gloves to protect your skin and avoid using hot water on cotton fabrics to prevent shrinking.
