Much like children, cars revel in muddy puddles, frequently squash bugs, and stall endlessly when it’s time for bed. Squelch vehicular squeals in a warm bath with today’s Groupon: for $20, you get a $40 gift card for car washes at Clean Freak Car Wash, with locations in Chandler and in Phoenix on 44th Street, Grand Avenue, and Camelback Road. While this Groupon must be redeemed at the location you purchased, the $40 gift card you receive can be used at any location.

Clean Freak’s finely tuned tar-hunting machines purify chassis with gentle treatments and an obsessive attention to detail in as little as three minutes. Hand-wielded scented towels and vacuums accompany each wash, purifying the car’s interior of clinging dirt, lingering odors, and foul language spilled in a fit on the road. The Nice ‘n Clean wash ($5) coaxes grime away from paint with a soap and soft-foam scrub, ensuring lingering shine with a spot-free rinse. The Freaky Clean ($8) scares off greater amounts of highway grit, combining the above services with a clear-coat protection treatment, an undercarriage power wash, and a triple-foam polish administered by wailing banshees. For hyper-sensitive vehicles, the Obsessively Clean wash ($10) amplifies newly imbued shine with Turtle Ice wax and a rim and tire cleaner, topping off the procedure with a scented air freshener and a spritz of Purell.

Clean Freak’s arched ceiling and jauntily rounded façade invite roaming cars into the long, science fictional feeling blue tunnel of the car wash, which magically deposits visitors and vehicles three minutes into the future on the other end.
