Engine oil on hands can be washed off by applying olive oil, floral water, gasoline or nail polish remover, vinegar, wood chips and laundry detergent, or alkaline powder. Engine oil is a mixture of several alkanes and is an organic substance. According to the principle of similar solubility, organic substances can also be used to dissolve engine oil. The chosen organic substances should also be water-soluble to avoid secondary pollution. Olive oil cleaning: Apply olive oil to the area with engine oil on your hands, gently rub a few times to fully soak, then wash with soap after a few minutes. Floral water cleaning: Apply floral water to the area with engine oil, then wash with soap after a few minutes. Gasoline or nail polish remover cleaning: Apply gasoline or nail polish remover to the area, then wash with warm water. Vinegar cleaning: Soak hands in vinegar, then soak in hot water, and wash afterward. Wood chips and laundry detergent cleaning: Wash with wood chips and laundry detergent together; wood chips can remove engine oil, and laundry detergent can remove the oil smell. Alkaline powder cleaning: Apply alkaline powder to the area with engine oil and wash.

The other day when changing the engine oil, I also got some on my hands. The best way to clean it is with dish soap and warm water from the kitchen. Don’t rush to rinse it off—directly pour dish soap on the oil-stained area and scrub to create foam. The oil will emulsify and turn white. Scrubbing twice usually removes most of it. For stubborn black stains, try the orange hand cleaner sold at auto repair shops—the kind with abrasive particles that won’t damage your skin. Never use gasoline or diesel to clean for convenience—those are too harsh and will dry out your skin, causing cracking and peeling. After washing, remember to apply some hand cream, as the additives in engine oil are quite damaging to the hands. If you don’t have specialized cleaner at home, a paste made of flour and baking soda applied for five minutes before washing also works wonders.

As a veteran auto mechanic with 20 years of experience, getting stained with engine oil is all too common. The most economical method is to first scrub with diesel fuel, but you must wear rubber gloves, otherwise your hands will turn red and become irritated. Nowadays, professional hand cleaning paste is preferred, available on Taobao for just over ten yuan and lasts half a year. For ordinary households, mixing White Cat dishwashing liquid with hot water works well—three times more effective than soap. The key is to scrape and scrub between fingers with your nails. If the oil stains turn black, don’t scrub too hard; apply some baby oil to soften them for half an hour before washing. Remember not to use steel wool, as it can scratch the skin and make the oil harder to clean. It’s best to remove rings and watches before washing, as oil trapped in jewelry crevices is particularly difficult to clean.

Last time I helped my dad fix his motorcycle and got my hands covered in grease, I found that mixing hand soap with edible soda was the most effective. Just take a spoonful of edible soda from the kitchen, mix it with hand soap to form a paste, apply it to the greasy areas, and wait three minutes—the grease will break down into a white paste. For stubborn stains in the nail crevices, use an old toothbrush dipped in the paste to scrub. My mom taught me to apply expired cream thickly for better sealing, leave it on for ten minutes, and then wash it off more easily. Be careful not to use disinfectant alcohol to wipe, as it won’t remove the grease and may irritate the skin instead. If you have coffee grounds at home, mix them with dish soap to scrub your hands for an exfoliating effect—your hands will feel especially smooth afterward.
