Slow motion adds dramatic effect to a scene, which explains why so many action heroes exit car washes completely soaked from trying to roll up their windows. Prepare for a climactic car cleansing with today’s Groupon: for $15, you get a premium car wash from Mr. Clean-It, servicing Johnson County (a $30 value). During the winter months or when temperatures dip below 45 degrees, car washes are performed in-house at Mr. Clean-It's Olathe facility.

The cleaning crews at Mr. Clean-It have been sanitizing cars since 1946, wielding safe, biodegradable products in their hunt for filth on mobile sojourns or at their Olathe shop. During the 15- to 20-minute premium wash, technicians attentively evict dirt, smudges, and slobber from impatient bridge trolls from the car's outer shell and sniff out crumbs from seats, carpets, and ashtrays with an astute interior vacuum. An interior window wash clarifies the glass from the inside, and exterior-glass scrub downs clear away environmental residue and give the car a chance to release pent-up inner beauty.
