What medicine does the dry cleaner use to wash clothes best?

The first thing I want to tell you is that dry cleaners are just a conventional name, and not everything in dry cleaners is dry-cleaned. Many things can't be dry-cleaned, such as down jackets. So there are not one or two kinds of potions used by dry cleaners. Even if it is really dry cleaning, there is still a difference between tetrachloroethylene and petroleum ether. As for the lotion, you can have more. According to the fabric, lining and lining of clothes, the washing products used are different. There are also various special decontamination potions, which are more professional.
