As Early Show national correspondent Tracy Smith points out, there's nothing dry about dry cleaning at all. Clothes are actually washed, in a solvent, one the federal Environmental Protection Agency calls it a possible-to-probable carcinogen, and you could be breathing it in, without even knowing it.
That was what happened with Mori Mickelson and her husband, Danny O'Brien.
The more they stayed inside their New York City apartment, the sicker they got.
"I would get dizzy, I would get headaches, just feel nauseous," Mickelson told Smith.
"I couldn't focus. Basically, my mind was floating away on me," O'Brien says.
It turned out, Smith reports, that the air in their apartment was contaminated with a toxic solvent leaking from the dry cleaner downstairs.
It's called perchloroethylene, or PERC, and it's used by three out of four dry cleaners nationwide.
Judith Schreiber, Ph.D., the chief scientist of environmental protection for the New York Attorney General's Office, says she "would classify PERC as a neurotoxin."
Schreiber says dry cleaners love PERC because it washes delicate fabrics without shrinking them or causing fading.
But, too often, PERC vapors can leak into nearby residences and offices, and Schreiber says long-term exposure can cause serious harm.
"You're at risk for neurological effects, liver and kidney illness, and increased cancer risk," she says.
The World Health Organization says PERC is a "probable human carcinogen."
The EPA classifies it as somewhere between a "possible" and "probable" human carcinogen, though at high dosages and over a long period of time. The agency doesn't say brief exposure to PERC, or long-term exposure to very low levels of the chemical will cause cancer. But the EPA admits studies of the carcinogenic effects of PERC in the general population don't exist. The EPA is currently doing a "risk assessment" of PERC, evaluating all research into its potential health effects, and plans to release its findings in about two years.
According to the EPA's Web site, "Breathing PERC for short periods of time can adversely affect the human nervous system. Effects range from dizziness, fatigue, headaches, and sweating, to incoordination and unconsciousness. Contact with PERC vapor irritates the skin, eyes, nose, and throat. These effects are not likely to occur at levels of PERC that are normally found in the environment. Breathing PERC over longer periods of time can cause liver and kidney damage in humans. Workers repeatedly exposed to large amounts of PERC in air can also experience memory loss and confusion. Laboratory studies show that PERC causes kidney and liver damage and cancer in animals exposed repeatedly by inhalation and by mouth. Repeat exposure to large amounts of PERC in air may likewise cause cancer in humans."
You may have gotten a whiff of PERC's strong, fresh scent at your cleaners but, once PERC evaporates into the air, you can't always smell it.
Mickelson had no idea her home was so contaminated until, one day, she literally collapsed from the fumes, and was rushed to the hospital.
"The city Department of Health did tests on us and our neighbors, and it was in our breath and our urine and in my breast milk and my neighbor's breast milk; it was basically everywhere," she says.
Even wearing dry cleaned clothes may put you at risk, Smith observes.
In the first study of its kind, Consumer Reports magazine measured PERC emissions from freshly dry-cleaned blazers and the results, Smith says, were "startling."
The magazine's Jean Halloran says, "We found that there was a small, but definitely increased risk of cancer from wearing freshly dry-cleaned clothes once or twice a week."
The industry calls that junk science.
"When handled properly, PERC is "extremely safe," says Nora Nealis, who runs the National Cleaners Association."
She says studies of workers at dry cleaners have found no increased risk of cancer, even after years of PERC exposure.
"I have friends and neighbors and family members who are in the dry cleaning industry," Nealis adds, "and I have no compunction whatsoever about their health or safety."
But some regulators aren't buying that.
Last month, California became the first state in the nation to ban PERC, calling it a public health threat. They ordered it phased out at dry cleaners over the next 15 years.
Officials there want them to use environmentally-safer methods such as "wet cleaning," which washes dry clean-only garments using special soap, and plain old water.
"Wet cleaning is great for casual wear, your khakis, your sweaters, your cotton man-tailored shirts," Nealis notes.
But it's not so good for structured garments.
Nealis showed Smith a designer jacket that wet cleaning caused to shrink, and left without what Nealis calls "that nice, finished, like-new look that you went to the cleaners for."
Some dry cleaners call their methods "organic." But that may not be safer than using perc because, the dry cleaners trade group says, there's very little regulation of what "organic" means in their business. All it means for sure is that the cleaning methods include the use of carbon, which could apply to virtually all methods of cleaning.
Another option? Stop buying clothes that require dry cleaning. That's what Mickelson did. She told Smith she now owns only one item, pair of pants, that is dry clean-only.
Though the dry cleaner beneath Mickelson's apartment no longer uses a PERC machine, she still worries about her family's exposure, telling Smith she worries "all the time" about its long-term effects, adding, "When one of us gets sick, I think, could this be something related to PERC? My greatest fear is that one of us is going to get cancer from it."
Experts say, if you live or work in a building that has a PERC dry cleaner, you may want to have your local health department check the level of PERC in the air.
And if your clothes come back from the cleaners smelling like chemicals, it could be a sign they have too much PERC on them, and you should take them back and have them redone.
Experts say unwrapping your dry cleaned clothes when you get home and airing them out could help, but if you take the plastic bag off inside your house, the PERC just goes into the air, where it can last up to a week. It's better to air dry cleaning out in an open garage or outside.
Mickelson says she airs out her dry cleaned pants by taking them for a walk around the block before bringing them home!

Our mother passed away May 8, 1993; after working as a Cleaner/Silk Presser for 30+ years, using "PERC" in a Dry Cleaners. Her "Lung Cancer" was untreatable and nonoperatable due to other factors including the location.
I also know a former Dry Cleaning worker,able to receive treatment for Lung Cancer (due to Dry Cleaning Chemicals)lives with a "Chronic Cough" and frequent doctor visits.
I truly hope the alternatives (according to your Consumer Reports,Studies,etc.) will be beneficial now and in the future for the environment,especially for Dry Cleaning employees.
And Triclosan used in soaps and detergents, is a diphenyl ether (bis-phenyl) derivative, known as either 2,4,4'-Trichloro-2'-hydroxydiphenyl ether or 5-Chloro-2-(2,4-dichlorophenoxy) phenol. It is related in structure to a number of bis-phenyl polychlorinated and bis-phenyl chlorophenol compounds. Due principally to the synthesis chemistry of polychloro diphenyl ethers and phenoxy phenols there is the potential for the formation of small amounts of unwanted trace by-products which are of concern. Beginning in the early 1970's and into the mid 1980's research revealed that phenoxy herbicides such as 2,4-D and 2,4,5-T (1,2,3), the major components of Agent Orange, the bactericide Hexachlorophene (4,5), various chlorophenols, i.e.- pentatchlorophenol, used in wood treatment (6), certain polychloro phenoxy phenols (7) and polychloro diphenyl ethers (8) and diphenyl ether herbicides (9) contained various low levels of polychlorinated dioxins and polychlorinated furans.
When utilized with the finest technology, perc is still the superior solvent of choice.

Yes, perc is a toxic chemical and must be used cautiously and correctly. Federal EPA and State counterparts have enacted, policed and enforced strict regulations on drycleaning operations to protect public health and the environment. Drycleaners are, in fact, the most highly regulated small businesses in the U.S.

Certainly, if a consumer smells a chemical odor in items they pick-up from the drycleaner they should immediately take them back for reprocessing. Hanging them in the garage or walking them around the block is not the answer.
If the cleaner does not correct the problem or it is a recurring problem, they should find another cleaner IF the chemical odor they smell is, in fact, PERC. In many cases the odor custome incorrectly identify as drycleaning solvent odor in their clothes is, in fact, from a finish the manufacturer has placed on the fabric.
%u2022 removing fats, oils, and greases;
%u2022 free of residual odor;
%u2022 chemically stable under all common use conditions;
%u2022 non-corrosive to the metals and other materials used in dry cleaning machinery
%u2022 easily removed from clothes; and
%u2022 energy and cost,efficient (can be easily distilled and is nearly 100% recycled.)
Using the best technology, there is virtually no exposure to this chemical. A human faces a much higher exposure, for example, using personal care products ie eye and face makeup, dental and oral hygiene, hair removal, hair care, skin and nail products. GET REAL!
I suggest everyone find their nearest CO2 or wetcleaner. www.FindCO2.com

I am extremely disappointed in CBS News' irresponsible and demonstrably false reporting. This report does not withstand scrutiny, and we EXPECT AN ACCURATE UPDATE AND AN APOLOGY.
www.livescience.com/humanbiology/070130_bad_drycleaning.html
Dry cleaning solvents, including perchloroethylene, pose miniscule risk when used in an environmentally responsible manner. Compiled %u201Cgreen%u201D dry cleaning research endorses liquid CO2 and wet cleaning. Research indicates liquid CO2 is NOT the best solvent- in fact, %u201CHangars%u201D franchises use wet-cleaning as back-up because of inability to remove stains effectively with CO2 however safe or stable it may be. And CO2 cleaning technology is proprietary to operating a Hangers franchise. There is questionable safety regarding GreenEarth technology siloxanewhich are combined organic/inorganic compounds.We keep hearing that yesterday's conventional wisdom is now %u201Cfalse%u201D, not because scientific investigation doesn't work; but because wisdom becomes conventional prematurely. The problem is a psychological, financial or prestige investment of researchers in their hypotheses and their earlier findings. This creates a bias of entrenched orthodoxies which are difficult to overturn. Another is the ill informed,sensationalist field of journalism, which gets hyper-excited over single studies. But we should look further. In fact,there is not a single thing in the world that cannot give you cancer.Health and science reporters,the FDA, the EPA need to have a better understanding of epistemological tangles and underpinnings. There isn%u2019t enough data available to make intelligent determinations on what really poses as cancer risk to humans other than life itself.
Perchloroethylene, as a regulated solvent, is safely disposed of employing the services of a certified waste handling management company approved of by the EPA.

Here is more info I would love to talk about CO2 cleaning
What is the CO2 Cleaning Process?
The CO2 Cleaning Process is a carbon dioxide-based garment cleaning process that has been developed for use by commercial and retail dry cleaners. Carbon dioxide is a non-flammable, non-toxic, naturally occurring gas that, when subjected to pressure, becomes a liquid and is a very effective solvent. Since the solvent is recognized as being environmentally friendly, it is not subject to any environmental regulations or liability potential from soil or groundwater contamination. CO2 CLEANING PROCESS FACT SHEET
What is the Carbon Dioxide Cleaning Process?
How does the cleaning performance compare with Perc? How difficult is the process to operate and learn?Are there certain fabrics that cannot be run in the CO2 Cleaning process?Is wrinkling a problem with the CO2 Cleaning process?
CO2 removes the soils wetcleaning can't and Wetcleaning removes the soils CO2 can't. The stains CO2 doesn't remove are the same stains Perc doesn't remove.

Here are Pros and Cons on dry cleaning solvents and alternatives.
CO2 FINDINGS CLASS IIIA SOLVENT: This process appears to be supplemented either with wet cleaning and a solvent process or outsourcing and has not been used long enough to gauge public acceptance. The process operates at 800 lbs psi, the detergent used is a hydrocarbon compound, is not labeled hazardous by EPA standards but is labeled hazardous by OSHA standards.
WET CLEANING: Additives to detergent such as amyl acetate, tannic acid, hydrofluoric acid as a rust remover, glycol as a softener, etc which are flushed into municipal water systems. High risk of shrinkage, not suitable for wool, cashmere, acetate, silks.
PETROLEUM SOLVENTS: Classified as a hazardous chemical because its burn and flashpoint is well-below the threshold of 140 degrees, has no carcinogenic effects on human health, but can cause skin irritation, can leave a distinguishable odor or residue.
PETROLEUM SOLVENTS and CLASS IIIA SOLVENTS: EXXON DF2000 synthetic hydrocarbon, highly flammable, same classification as Petroleum Solvent.
The dry cleaner housed in the establishment Ms. Smith refers to is highly atypical (not typical) of dry cleaners who use world-class, environmentally-friendly technology. In fact it is safe to say, that dry cleaner in Ms. Smith%u2019s story was/is using terribly antiquated technology which in no way should be confused with today%u2019s world-class technology, no matter what type of solvent is being used. Today%u2019s technology (including perchloroethylene), consumes a hugely significant decrease in solvent consumption, are dry-to-dry, (meaning go in dry, come out dry with a vacuum vent that does not allow the door to be opened until any vapors present are well-under established safe limits) are closed loop, come equipped with triple-safety control systems, do not contribute to air emissions, or ground contamination( are equipped with safety spill *****) do no emit waste water, and any waste deemed hazardous is contained, and shipped to a waste facility that, in turn, recycles and purifies the waste.
Proper wetcleaning doesn't use amyl acetate, tannic acid, hydrofluoric acid as a rust remover, glycol as a softener as stated in an eailer post. These are stain removal agents that are used by hand and removed from the garment prior to wetcleaning. These solutions are then disposed of as hazardous waste.
Professional wetcleaning is safe for wool, cashmere, acetate & silk. Wool & Cashmere actually feel 5 times better after being professionally wetcleaned. The problem is some cleaners don't buy the expensive wetcleaning equipment and do it in a regular washer. Then the is problems. Like in the story, you can see they idea of wetcleaning was a home washer, and you saw the lady put the jacket on with sleeves 6 inches short. THAT IS NOT WETCLEANING.
CO2 & Wetcleaning will produce the results demanding consumers require.

Tetrachloroethylene exposure and risk of schizophrenia: Offspring of dry cleaners in a population birth cohort, preliminary findings.
My wife and I have operated a 100% wet cleaning operation for three years. We may, in fact, now be the largest in the US now with 5 locations. You do not achieve this type of growth with a process that was reported, in this news piece, to ruin clothes. The NCA spokes-woman came across a lobbyist protecting the interests of her membership. Of course, we'll not be joining to her organization as she clearly would not properly speak for us as wet cleaners.
In our area several dry cleaners have left the industry due to landlords opting out of leases because of site contamination. This bodes well for open minded dry cleaners willing to consider new technologies or those looking for new business opportunities. More consumers will discover wet cleaning. Savvy dry cleaners will too.
NO DRY CLEANER SHOULD BE USING ANYTHING LESS!!
Every dry cleaner should also have the ability to wet clean at least 50 to 60% of the garments brought to them, without problem.
The operator should, at a minimum, be fully capable of maintaining the dry cleaning unit daily, weekly, monthly, semi-annually and annually to ensure optimum efficiency, optimum safety, and optimum care of the environment and a client%u2019s wardrobe.
Anything less, is completely unacceptable.
So no matter what type of solvent is in use (and they all have their pros and cons), there simply are no excuses. If you are not a master of this trade, you have no business being in the dry cleaning business. Period!
The state of California will provide cleaners grant money to change to CO2 or wetcleaning. These are the methods the state officials found to be the safest. They originally included Siloxanes (Green Earth) , but after review dropped it from their recommended technology.
