The sign in front of Manhasset Hand Wash & Detail Center reads "100% Hand Car Wash," a tip of the cap to the old-fashioned service its technicians provide. From inside a full-service car wash tunnel, they draw on Rain-X products and Rosie the Riveter-levels of elbow grease to administer tiered hand-wash packages each named in tribute to the East Coast, such as the Bay Breeze Wash and Light House Wash. The staff works under the gaze of Elvis Presley and vintage automobiles, thanks to a wall-sized art piece designed like a strip of black-and-white film. As cars receive a hose blast from the past, their owners wait in a modern shop filled with automotive accessories, including a Technicolor forest of air fresheners. The cleaning services offered are especially useful during the winter season as a measure to prevent the onset of rust and corrosion from sea salt on the roads.
