Baltimore City Paper also named Canton Car Wash Best Car Wash on its Best of Baltimore list in 2009:

Leading Edge’s auto body and mechanical repair shop offers aid to broken, busted, and bumped-up cars of any make or model. With this deal, customers get an oil and filter change ($19.95), a front-to-rear tire rotation ($40), and an exterior car wash ($12) that will leave the car’s shell clean enough to lick, even if it doesn’t undo the emotional damage from the ink-filled egg incident. An oil change keeps the car's bloodstream free of corrosive buildup, and a tire rotation elongates the lives of the tires and ensures treaded safety. In addition, Leading Edge will inflate tires to proper pressure levels, top off fluids, and visually check brakes. A $6 Environmental Protection Agency fee is also included with this deal.

After a successful career in manufacturing, Will Speace was looking for a change of pace. A long-time car buff, he decided to create Columbia Junction Car Wash to test his business acumen and sharpen his service skills. The flourishing business, carried on today by his wife and two sons, treats car owners to a variety of gentle and high-tech services. Soft-cloth or laser-wash technology wipes away road grime, while a la carte detailing services tackle upholstery, bug removal, bug burial, and rims.

Excessive Detail's car caretakers polish roadsters of all shapes and sizes. When they aren't scouring cars, motorcycles, RVs, and boats, they're repairing windshields, removing dents, and shielding paint jobs with protective films. They also ready vehicle peepers for safer nighttime jaunts by installing HID headlights or purging old lamps of haze for clearer beams, reducing the risk of collisions with families of yield signs trying to cross the street.
