Waves Car Wash, West Roxbury

Though it has adopted advanced technology in its cleaning tunnels, Waves Car Wash still powers some of its services with the original drier: the sun. On the roof are 160 solar panels that soak up rays, fueling up to 20% of the facility's electrical output. The panels reflect Waves Car Wash's emphasis on green initiatives—others include biodegradable cleaning products and a recycling system for waste water. The shop also channels its vehicle-sprucing expertise to benefit charitable programs such as Wash for a Cause and Wash Away Thirst.

Meticulous treatments and a familial ambiance have enabled the wash spot to achieve its current level of altruism. Car washes ranked from Basic to Extreme glamorize vehicles with water, wax, and wheel pampering. Detailing, buffing, and headlight-restoration services leave cars looking so flashy that they'll begin attracting disco balls. Enamored patrons can even join the Always Clean Unlimited Wash Club, which grants them infinite cleanings in exchange for a monthly fee.
