Which volatile organic compound is commonly used in dry-cleaning?

Tetrachloroethylene is commonly used in the dry-cleaning process due to its solvent properties, which allow it to dissolve greasy stains and dirt effectively without damaging delicate fabrics. This compound, often referred to as perchloroethylene or PERC, is recognized in the textile cleaning industry for its strong cleaning abilities and low flammability, making it a preferred choice for commercial dry-cleaning operations.

The use of tetrachloroethylene in dry-cleaning aligns with its chemical characteristics, as it is effective at removing oil-based stains, which water cannot address effectively. Additionally, it evaporates easily, facilitating the drying process after cleaning. Its widespread application in the dry-cleaning sector has also led to regulatory considerations regarding its environmental and health impacts, prompting discussions on appropriate handling and disposal practices.

While other compounds such as trichloroethylene and methylene chloride have cleaning properties, they are not primarily used in the dry-cleaning industry. Chlorine is a disinfectant and bleaching agent but does not possess the solvent properties suitable for fabric cleaning like tetrachloroethylene does.
