According to Newton's Fourth Law, the more you drive your car, the more debris it attracts—repelling aerodynamics, the opposite gender, and gravity itself. Smooth your horseless carriage's exterior with today's Groupon for a choice of car wash from Shiners Car Wash, located on Aldersbrook Road. Shiners Car Wash's highly trained and friendly staff shampoos, conditions, and blow-dries dirty drivables, ensuring that exteriors look their best and interiors are free of debris and stowaway gnomes. A regular car wash, like a bubble-wrap jumpsuit, protects your car's finish against surface erosion and environmental damage. Customers can relax in the comfortable waiting room knowing that they are helping the environment by forgoing an at-home wash and taking a more eco-friendly approach that does not pollute sewers and the minds of neighbourhood children.
