Soak the contaminated part of the work clothes in hot water at about 60°C for a while, then take it out and sprinkle a small amount of alkali powder and an equal amount of laundry detergent, and scrub it by hand. Then, rinse with clean water, and then wash again with laundry detergent. Cut the soap into pieces and dissolve it in boiling water, then put the work clothes in the soap solution and scrub.

Last time I got engine oil all over my sleeves in the garage, I figured out a few methods. First, use kitchen paper to absorb excess oil to prevent it from spreading. The most convenient option is dish soap—squeeze it directly onto the stain and scrub, then rinse with cold water after the grease breaks down. If dish soap doesn’t work, try gasoline or industrial alcohol, but make sure to work in a well-ventilated area and gently dab with a cotton swab, followed by repeated washing with laundry detergent to remove the chemical smell. For particularly stubborn stains, use a professional oil stain spray, let it sit for 15 minutes, then toss it in the washing machine. Finally, a reminder: never use hot water, as it will cause the oil to seep deeper into the fibers, making it harder to clean. Pure cotton work clothes are easier to handle than synthetic ones.

I have a set process for cleaning oil stains. First, deal with fresh oil stains: apply a thick layer of cornstarch or baby powder on the stain, wait 20 minutes, then brush off the powder with a toothbrush after absorbing the surface oil. Next, focus on treatment by applying a thick coat of dishwashing liquid (the one in blue packaging), wait half an hour for the enzymes to work, then rub and rinse with cold water. For old stains, make a paste with white vinegar and baking soda, apply it overnight. Never use laundry detergent directly to scrub, as the particles can damage the fabric. Finally, add some oxygen-based bleach when machine washing, which can remove oil and protect colors. Remember to check before drying; if not clean, repeat the process and don’t rush to dry.

Oil stains should be handled differently based on their type. For regular mineral oil, simply apply undiluted dishwashing liquid and scrub. Synthetic oil is more viscous and requires stronger treatment—I always keep a stain remover pen handy, dabbing the edges to prevent spreading. There's also a traditional method: apply butter to both sides of the stain; the mutual dissolution of fats makes it easier to wash off. Use the heavy-duty cycle on your washing machine with laundry detergent and half a cup of white vinegar. Hang the clothes inside out when drying, as UV light helps break down residual oil. Be cautious with dark-colored work clothes—avoid soaking them too long to prevent color fading.

I follow a four-step process to clean oil stains: First is pre-treatment—sprinkle salt on fresh oil stains to absorb the oil. Second, apply makeup remover oil for emulsification, which is gentler than dish soap. Third, use 75% alcohol for spot cleaning, which is most effective against penetrated oil. Finally, soak in warm water with laundry detergent and gently rub. For synthetic fabrics, avoid solvents—instead, boil soapy water, let it cool, and soak for two hours. Always spray collar cleaner on work clothes after each wear to prevent oil buildup. Wear rubber gloves to protect your hands during cleaning. For stubborn stains, multiple cold water rinses work better than vigorous scrubbing.

Remove workwear oil stains as early as possible. I once had engine oil soak through my sleeve and found that a paste of flour mixed with dish soap applied for three hours worked well. While gasoline is effective, it damages fibers, making professional degreaser sprays a safer choice. For daily preparedness: spray collar cleaner on both sides of the oil stain, let it sit overnight before washing—effortless and thorough. Avoid direct sunlight after washing; air-drying is best. For work clothes frequently exposed to oil, consider monthly with a laundry enzyme soak to extend their lifespan. Remember to ventilate the area during treatment, as strong odors can be harmful.
