Oak Forest Dry-Cleaners

from website: When you think of “green” businesses your dry cleaner is probably not the first place that comes to mind. Here at Oak Forest we do all that we can to save energy and shrink our footprint on the environment. First and most important is our use of System K4. Unlike most dry cleaning solvents, K4 is a completely non-toxic, non-hazardous material. It is completely biodegradable and it doesn’t leave that harsh chemical smell on your clothes.
