Name: Clean Green Carpet Cleaning. Descripton:At Clean Green, we use an eco-friendly cleaning system free of harsh chemicals. We pre-treat all areas with an all natural citrus based cleaner that breaks up the soils. Then our certified technicians extract the cleaners and soils with fresh clean softened water. Our truck mounted unit with high suction and heat, removes soil and restores ground in traffic areas. Finally, a protectant layer is added to help keep stains away for six months or longer!
