Alcohol: The oil can be removed by smearing alcohol on clothes. Alcohol can be soluble in both organic solvents and water. The higher the alcohol concentration, the better. It is better to use absolute alcohol.
Gasoline: The oil stains on the clothes can be wiped with gasoline first. If the oil stains are too heavy, they can be wiped with alkene and turpentine. After the oil stains are melted, they can be washed with general washing methods.
Degreasing cotton: use a piece of degreasing cotton not smaller than the cigarette case to dip in gasoline, and gently pat it from the center of the collar to both sides. Do not dip too little gasoline, and then wash the clothes regularly.
Remove stains with absorbent paper: cover the front and back of the clothes stained with grease with absorbent paper, blotting paper, etc., and then iron them with an iron, and constantly change the paper. When heated, the oil will melt and be absorbed by the absorbent paper to remove the oil stains.
