Dry cleaning is simply to clean without using water. It can be any solvent other than water. Dry cleaning uses perchloroethylene to remove soil and stains from fabric. It is able to dissolve greases and oils and prevents shrinkage, loss of color, and fabric distortion.
The process begins with the pre-treatment of spots and stains using special cleaning agents. The garments are then loaded into a machine and washed with perchloroethylene, then pressed and packaged.
Laundry cleaning (to launder) a garment means to clean it with water and other agents such as soap, detergent or softener.
