Eco Detail, LLC's founder wanted a car cleaning service that delivered results while addressing his ecological concerns. Since he couldn't find such a business, he started it. Now he uses steam-cleaning technology on both interiors and exteriors, pairing the water vapor with natural, biodegradable products. He points out that, while not entirely waterless, steam cleaning uses less than a gallon of water to clean an entire vehicle, without producing water waste or run-off. Moreover, the technology is compact and easily transported, meaning that cleaning crews roam freely to wash dirty cars wherever they may park, be it in a driveway, at the office, or atop a runaway parking train.
