Dry Cleaning: The Old Way vs The New
Still taking your clothes to your local dry cleaners? Have you asked what type of solvents they use? Probably they are sticking to the tried and true, which is a method that includes a volatile toxic solvent called PERC, also known as perchloroethylene, PCE, or tetrachloroethylene. Labeled a probable carcinogen by the World Health Organization and the U.S. Environmental Protection Agency, it is also a probable neurotoxin. Studies have exposed PERC as a link to cancer and reproductive problems among dry cleaning workers. Used by approximately 85% of dry cleaning services, the chemical is also used to degrease metal parts and can cause headaches, nausea, dizziness, as well as skin, eye, nose, and throat irritations. As it accumulates in the system, it can also cause liver and kidney damage. Additionally it is a contributor to ground water contamination.
As these reports become better known, many dry cleaners are claiming that they are going greener. But often they have just exchanged PERC for another type of hydrocarbon solvent called DF-2000, which is a petroleum product and only slightly less toxic. Because new methods of true green cleaning require new equipment, many shops choose to stick with the old way. As of today, the industry is not regulated and so the health standard remains ignored.
The Organic Alternative
Many conscious dry cleaning store owners are now converting to a form of “wet” cleaning where a food-grade level of carbon dioxide, which at room temperature is normally a gas, is put under pressure. This converts the gas to a liquid, which then carries biodegradable soap to do the cleaning job. When the cleaning cycle is finished, the carbon dioxide turns back into gas, which can be reused. In this manner, clothes dry instantly and are odorless. Dry cleaning workers are not exposed to toxins, the machines are able to function at low temperatures, and carbon dioxide is a totally renewable resource, so the entire process works in harmony with solid green standards.
Steam Cleaning
Dry or wet cleaning is not always necessary for getting clothing clean. Many consumers are opting for steam cleaning their clothing at home with available steam cleaning kits that do the job extremely well. Less expensive, this is the ultimate eco-friendly way to treat your garments.
The Future
As people become more aware of the hazards of conventional dry cleaning, demand will be made for regulations and standards, much like we see with organic food labeling and the like. When dry cleaning practices become more transparent, we will have a clear way to make our eco-friendly choices when it comes to our garments and our health.
Notes:
Besides being toxic, conventional dry cleaning also creates wear and tear on your garments over time.
Recycle your metal hangers back to the store.
