Dry cleaners belong to the service industry, mainly providing cleaning and nursing services for clothes and household items. They usually focus on cleaning suits, wool, silk and other clothes that are easily deformed when exposed to water, so they are also called "dry cleaners". In addition, dry cleaners may also provide peripheral supporting services, such as being adjacent to other stores and shopping malls, to provide customers with a more convenient shopping experience. The service of dry cleaners meets the multi-level needs of society, so it can also be regarded as a part of social subsidiary industries. Dry cleaning refers to a commercial form of providing laundry service for the public. Dry cleaning service providers transform their product system, service system, technology system and brand system (including trademarks and trade names) into clean and reusable clothes in the form of services, thus prolonging the service life of clothes and ensuring the beauty of wearing.
