For decades dry cleaners have been relying on Perc* to offer their clients professional cleaning results. While Perc is known to be a human carcinogen, 80-90% of the cleaners are still using it. We,GREEN4U, use only quality purifiedwater andnon-toxic, natural solvent. The natural method leaves no toxic residue or odor on your garments and eliminates allergic reactions due to toxic chemicals, which means no harming the people and the environment but still brings the best result.
