Like slip 'n' slides, car washes provide an efficient way to clean important items and host inexpensive children's birthday parties. Carefully cleanse your pride and joy with today's Groupon: for $35, you get an express exterior car detailing at Nature's Hand Car Wash in Morton Grove (up to an $80 value).

With acclaimed products and skillful attention to detail, the team of expert automotive artists at Nature's Hand Car Wash carefully purges, polishes, and pampers rides. The main event of the exterior detail is the application of Meguiar's Synthetic Sealant 2.0—a polymer-paint sealant—to lock in car color and protect paint from sliding off during family drag-race competitions. Wheel whisperers also lovingly lave tires back to their original asphalt-accessorizing black hue, and they polish trim and windows until they're free of spots, streaks, and "Kick Me" signs mischievously affixed by jealous bicycles.
