Here are some methods to remove oil stains. You can try them so that your clothes can be worn.

How to wash oily clothes:

Many times, we cannot clean greasy clothes with water, and we have to use a dry cleaning machine to wash them because grease is insoluble in water. "There are two types of oil stains: animal oil and vegetable oil. Basically, the ones we encounter more often are animal and vegetable oils.

There are two most commonly used methods for removing animal and vegetable oils. One is to use alkaline substances to undergo saponification reaction with oil stains, turning the oil stains into water-soluble saponified products for removal; the other is to use surfactants, which have both hydrophilic polar groups and lipophilic non-polar groups in their molecules, which can greatly reduce the surface tension of water and the interfacial tension of the liquid, thereby achieving the effect of degreasing.

The reason why toothpaste can remove grease is that its main ingredient is surfactant, which can reduce the surface tension of the aqueous solution, causing the oil film covering the surface of the fabric to shrink into small particles, and then use friction and the impact of water flow to separate the small oil droplets from the fabric surface, thereby achieving the purpose of removing grease.

How to wash off oily clothes? This problem is encountered by many people in life, but it is also difficult to solve. The above methods are relatively practical methods of removing oil stains, which means we can choose these methods in our daily life, but it is still best to avoid getting oil stains on your clothes as much as possible in life.
