Dry cleaning is a cleaning process for fabrics that uses solvents instead of water. This method is particularly effective for delicate materials like silk or wool that may be damaged by traditional washing. The solvent removes dirt and stains without causing shrinkage or distortion of the fabric. During dry cleaning, garments are placed in a machine that resembles a washing machine but uses a chemical solvent, often perchloroethylene, to clean the clothes. After the cleaning cycle, the clothes are dried in the same machine, ensuring they come out clean and fresh without the need for water.
