Modern dry cleaning machines use a closed-loop system in which the chilled air is reheated and recirculated. This results in high solvent recovery rates and reduced air pollution. In the early days of dry cleaning, large amounts of perchloroethylene were vented to the atmosphere because it was regarded as cheap and believed to be harmless.
Ventilation should be considered for its relationship to "venting" for appliances and combustion equipment such as water heaters, furnaces, boilers, and wood stoves. Most importantly, building ventilation design must be careful to avoid the backdraft of combustion products from "naturally vented" appliances into the occupied space.

If the label reads "dry clean only," you run the risk of damaging, shrinking or fading your clothes. Delicate fabrics (think silk, cashmere and leather), embellished items and formal attire, like ...
And while about 85 percent of the nation’s estimated 36,000 dry-cleaning shops still use perc as their primary solvent, according to the National Institute for Occupational Safety and Health, many cleaners have started to embrace the new methods. The environmentally preferable choice for dry cleaning, experts say, involves little more than water.
With my own machine, this process takes about 10 minutes from beginning to end, and while it can be a bit messy (I didn't know what to expect the first time and did not provide a drip tray for the ...
Wet cleaning machines have controls that allow them to safely and efficiently clean a wide variety of garments in water. Detergents and spot removers are made of ingredients that are safer for workers and the environment, yet are as safe and effective at removing soils, stains and odors as dry cleaning solvents.
