1. When the clothes are dry, apply the stock solution of laundry detergent to the oil stain, let it stand for 5 minutes after application, and then wash it normally.

2. It can be repeatedly wiped with potassium permanganate aqueous solution, then repeatedly wiped with hydrogen peroxide, and finally rinsed with clean water.

3. Sprinkle chalk powder or magnesium oxide powder on the stain, and then remove it with net powder in a few days. Through the adsorption of powder, the oil stain will disappear, leaving no trace.

4, you can scrub with gasoline, and then put a piece of oil-absorbing paper or cloth on the top and bottom of the clothing oil stain, and iron it with an iron to further evaporate the oil stain and be absorbed by the paper or cloth, and iron it repeatedly until all the oil stain is absorbed.
