2. If the oil stain on the clothes is big and stubborn, it is necessary to attack oil with oil. Gasoline is an organic solution, which can dissolve oil stains and other substances. After washing the oil with gasoline, it needs to be cleaned with phosphorus-free washing powder.

Extended data:
Most greases are used for lubrication and are called antifriction greases. Anti-friction grease mainly plays the role of reducing mechanical friction and preventing mechanical wear. At the same time, it also plays a protective role in preventing metal corrosion and sealing dust. Some greases are mainly used to prevent metal from rusting or corrosion, and are called protective greases. For example, a few lubricating greases specially used for sealing, such as industrial vaseline, are called sealing greases, such as thread compound. Oils and fats are mostly semi-solid substances with unique fluidity.
The working principle of grease is that the thickener keeps the oil in the position that needs lubrication, and when there is a load, the thickener releases the oil, thus playing a lubricating role.
