Dry Cleaning

Dry Cleaning is a process of cleaning clothes and textiles using a chemical solvent other than water. This method is used to clean fabrics that degrade in water, and delicate fabrics that cannot withstand the rough and tumble of a washing machine and clothes dryer. It can eliminate labor-intensive hand washing.

Process[edit | edit source]

The process of dry cleaning involves the use of solvents to remove soil and stains from fabric. A chemical solvent (other than water) is used to clean clothes. The most commonly used solvent is perchloroethylene (commonly known as "perc"). The process begins with the pre-treatment of spots and stains using special cleaning agents. The garments are then loaded into a machine resembling a large washing machine.

Solvents Used[edit | edit source]

The most commonly used solvent in dry cleaning is perchloroethylene, which is a colorless, nonflammable liquid. Other solvents include 1-bromopropane and petroleum spirits.

Environmental Impact[edit | edit source]

Dry cleaning has been known to have environmental impacts. Perchloroethylene is classified as a hazardous air contaminant and a potential human carcinogen. Many dry cleaners have installed equipment to reduce perchloroethylene emissions.

Health Risks[edit | edit source]

Exposure to high concentrations of perchloroethylene can cause dizziness, headache, sleepiness, confusion, nausea, difficulty in speaking and walking, unconsciousness, and death. Long-term exposure can lead to liver and kidney damage.

Alternatives[edit | edit source]

Some alternatives to traditional dry cleaning include "green" dry cleaning using CO2 or water as a solvent, and home dry cleaning kits.
