Dry cleaning is a process used to clean clothes and textiles without the use of water. Unlike traditional washing, which relies on water and detergent to remove dirt and stains, dry cleaning uses chemical solvents to clean fabrics. This method is particularly effective for delicate materials that might be damaged by water, such as silk, wool, and certain synthetics.
The use of perc in dry cleaning has raised environmental and health concerns. Perc is classified as a toxic chemical and can pose risks if not handled properly. Due to these concerns, there has been a shift towards more eco-friendly alternatives, such as hydrocarbon cleaning, liquid carbon dioxide, and silicone-based solvents.
