Professional clothes washers, also known as drycleaners, are individuals who specialize in cleaning clothes and other fabrics without the use of water. They use a variety of solvents and detergents to remove dirt and stains from garments, and then press and finish them to restore their original appearance. Drycleaning is often used for delicate fabrics that cannot be washed in a washing machine. Professional clothes washers must have knowledge of different fabrics and how to properly care for them.
