One of the strangest interviews I ever did as a cub reporter was at the Russian & Turkish Baths. It was done entirely in the nude. It came floating back to me as I watched my dusty car get soaped up at another cleansing New York City institution: the West Side Highway Car Wash. Here, cars of all makes and models—from proletarian to presidential—get spanking clean while drivers watch through a plate glass window. Colorful neon lighting gives a happy disco feeling to each cleaning cycle. The car wash is 71-years-old and has a vintage electric sign, but it continues to innovate with eco-friendly products, water recycling and surprisingly artisanal snacks. Delicious Underwest Donuts operates a small coffee shop inside and makes fresh donuts in flavors like "car wash" (lavender-vanilla) upstairs. There's always a line at this popular destination. Which all goes to show that in the naked city, grime actually does pay.
