In America’s sunniest city, Denver, car-wash day is every day. Or at least it could be. After drivers return from a trip to the mountains or the dusty desert, hand washes and waxes ensure that Denver cars stay in good shape. Car washes here often offer more extensive detailing, too, so you can keep the undercarriage, wheels, and interior of your vehicle clean and ensure worn-down elements are tended to. Service centers have a significant interest in maintaining your ride, since you’d likely rather return to trusted automotive technicians for years than head to the dealership every decade or so.
