Free from aerodynamics-inhibiting dirt and grime, clean cars can focus on what they were originally built to do––dominate in the 200-meter butterfly. Smooth your vehicle's surface with today's Groupon: for $15, you get a $30 gift card to any Boomerang Carwash location, which may be used over multiple visits.

With drive-thru car-wash technology that executes quick environmentally friendly washes, Boomerang Carwash transforms armies of unkempt automobiles into fleets of clean cars. Auto-tidying technicians greet each customer upon arrival with a sucker and a menu of three cleaning levels, and greet cars with their best honk impressions. The basic Boomer's Good car wash ($6) purges fenders and underbodies with biodegradable solutions, purified forms of detergents, and under 30 gallons of fresh water per car. Condition cars' hard outer shells with Boomer's Better wash ($9), boosting full-body shine with a Tri-Color foam and safeguarding paint with DuraShield protectant with Body Armor. Boomer's Best ($12) adds on a complete and long-lasting tire shine and wheel cleaner, keeping treads clean, polished, and free from profane haikus written in their dust.
