Like bargain-bin spray tan kits or bags of Flamin' Hot Cheetos, home car washing can leave unsightly streaks that mutely broadcast one's poor decisions. Make the right choice with today’s Groupon: for $3, you get a basic wash at Touch n Go Express Car Wash (a $6 value).

An experienced crew of vehicular beauticians sends dirt-stained sedans and slovenly SUVs through a powerful, 95-foot conveyor wash that blasts them with a cascade of soapy water to remove caked filth and restore shine. The basic wash package includes a high-impact tunnel wash, streak-free dry, and a vacuuming service that hunts dust bunnies frolicking in crusty carpet meadows. While streaming jets swathe your car’s underbelly with biodegradable soaps, an ultrasonic sensor identifies the vehicle type and accurately measures its dimensions to ensure a safe and effective wash. Hoses then release fragrant bouquets of soap and foam to gently clean surfaces and rinse away bad memories of muddy potholes. After passing through the tunnel’s multiple spot-free rinse arches, rides are greeted with a bellowing host of air dryers that chant ancient desert hymns to scare away lingering water molecules. From start to shimmering finish, car washes take about five minutes and are suitable for most vehicle types.
