Cleaning method 1:

Make a thick paste with baking soda and a little cold water and apply it to the stain;

Leave it for 30 minutes and remove the baking soda when it is completely dry.

Mix the laundry detergent with an equal amount of baking soda, and then wash with water that is hot (as hot as the object can stand).

Washing method 2:

Sprinkle baking soda powder first to absorb the oil stains on the clothes;

Don't dip the clothes in wetness, smear some enzyme laundry detergent on both front and back sides of the stains, and let it sit for a while;

Put the clothes into a washing machine with enzyme laundry detergent, and wash it with the highest water temperature that the clothes can withstand;

Note:? Do not use petrochemical solvents to clean up motor oil, which is highly flammable. Do not tumble dry either, even if you have rinsed with water; always let the clothes air dry naturally.

Also, motor oil can be washed with organic solvents such as alcohol, gasoline, and detergent.

Motor oil is a mixture of several epitaxial hydrocarbons, which are organic, and according to the principle of similarity and solubility, we can also use organic substances to dissolve motor oil, but it is best that the organic substances we choose can also be dissolved in water, so that it will not cause secondary pollution. The most convenient is to choose alcohol, alcohol can be soluble in both organic solvents and water. Alcohol concentration of course the higher the better, preferably anhydrous alcohol.

If it is a little, with the wind oil essence (small round, red that kind, inside is yellow) wash, very easy to clean, I tried many times, and what oil stains and so on can be off. With the wind oil essence coated with a little in the clothes to get to the place of the oil, put a few seconds on the good, and then wash clothes and wash a piece of it off, and simple.
