Clean at what cost?

Looking on line to find out if it was safe to wash silk and rayon, I came across a frightening piece of information. I didn’t know . . . did you, that:

Almost all dry cleaning establishments in the country clean with perchloroethylene (perc), a probable carcinogen, neurotoxic chlorinated solvent that bioaccumulates in fat and is suspected endocrine disrupter, meaning it is a chemical that may confuse the body into thinking it is estrogen?

I got this from www.care2.com/channels/solutions/home/133

With information gathered from this site, I now safely wash the clothes I used to have dry-cleaned.
