Unlike cats and germaphobes, automobiles need to be reminded to wash themselves. Drop a blatant hint to a lazy ride with today's Groupon: for $7, you get a basic hand car wash at Splash Hand Car Wash (up to a $22 value). This Groupon is valid at locations on Richmond Avenue and Westheimer Road.

Splash Hand Car Wash and Detail's skilled sparkling gurus thoroughly examine each vehicle to neutralize filthy smudges and puddle backwash. After a gentle cleansing with lamb's wool mitts, auto aestheticians will proceed to chamois-dry vehicles, thereby eliminating any drag-creating buildup that could potentially add milliseconds onto land-speed records and urgent trips to the drive-thru. They will also relieve wheels and tires of dirt and grime before dramatically increasing tread cred with an Armor All tire treatment.

A vacuuming, light wipe down of the dashboard, and a window cleaning will put a twinkle in your car's eye and an amorous flutter in the oil-pumping hearts of other cars. In addition to brightening hoods and breaking down dirt, Splash Hand Car Wash and Detail can further protect vehicles from the elements with leather cleaning, carpet shampooing, waxing, and express detailing services, although today’s Groupon is not valid toward these services.

This Groupon is valid for vehicles as large as Suburbans, Excursions, four-door crew cabs, and large vans. Consult the service page for more info.
