There's a glint and a glare bouncing off Greenhill Car Wash's rooftop. It's up there with the building’s solar panels, soaking up the sun's rays to power their computerized tunnel with clean, renewable energy. In their tunnel, soft foam and a pressure spray gently scrub the grime off of autos, while a lather of triple foam adds gloss, and a rust inhibitor staves off deterioration. Committed to keeping both cars and the environment clean, they also employ a water-recycling system that uses 60–80% less water than the standard commercial car wash. At their two locations, they remain true to their green car-washing techniques, and make their washes last longer by rendering thorough detailings or taping a scathing lampoon of dirt to each bumper. Detailers can return cars to a like-new appearance by rubbing exteriors with clay bars to remove contaminants, applying UV creams to interiors to prevent sun damage, and hand waxing paint jobs to a showroom shine.
