Dry cleaning is not mysterious. Dry cleaning solution can dissolve and remove oil stains on clothes, such as natural fibers such as wool and silk, which are easy to shrink, deform and fade after washing, but dry cleaning can be handled very well, and even man-made fibers such as polyester can be dry cleaned very cleanly. These fibers will still have some oil stains after washing, but these stains may be removed after dry cleaning. Washing clothes by penetrating, dissolving and releasing olefins with chemical solvents can achieve the effect of removing oil stains or stains, which is called dry cleaning. The so-called "dry cleaning" means that the clothes are dry before washing, and the clothes taken out of the dry cleaning machine after dry cleaning are also dry. However, in the process of dry cleaning, the clothes are soaked, washed, dried in the drum of the dry cleaning machine, and then dried, and the chemical solvent contained in the clothes is recovered and dried to complete the whole dry cleaning process. Dry cleaning is a kind of washing method that has only appeared in the last hundred years. After dry cleaning, the clothes will not be deformed or faded, and the fabric will not be damaged. It also has the special efficacy of disinfection and sterilization.
Dry cleaning clothes will come into contact with harmful substances such as tetrachloroethylene. Therefore, don't wear clothes that have just been dry-cleaned, dry them outdoors first to reduce the harm to the human body.
My opinion: Unless it's super-high-end clothes, it's usually all right after washing. Just iron it again and it will be ok.
