Trockenwäschen

Trockenwäschen refers to a cleaning method for textiles that does not involve water. Instead of water, a solvent is used as the cleaning agent. This method is commonly employed for delicate fabrics that could be damaged by water washing, such as silk, wool, leather, and certain synthetics. The process typically involves placing the garments in a specialized machine where they are tumbled with the solvent. The solvent dissolves and carries away dirt, oils, and stains. After the cleaning cycle, the solvent is extracted and often recovered for reuse. The garments are then dried, usually in the same machine or a separate drying unit.

The solvents used in Trockenwäschen vary, but common examples include perchloroethylene (perc), hydrocarbon solvents, and newer, more environmentally friendly alternatives like silicone-based solvents. Each solvent has its own properties and suitability for different types of fabrics and stains. Specialized dry cleaning facilities are equipped to handle this process safely and effectively, as many solvents are flammable or can pose health risks if not managed properly.

Trockenwäschen is distinct from simply airing out clothes or using dry cleaning sheets, which are at-home methods for freshening garments. True dry cleaning involves a chemical solvent and specialized equipment. It is a highly effective method for removing greases, oils, and many types of stains that are difficult to remove with water-based washing.
