After five years of perfecting cars for area dealerships, Car Pretty’s purification professionals now share their services with the public, restoring cars’ interior tidiness and exterior luster with meticulous detailing services. Technicians begin each 20-minute wash by lathering exteriors with wax-infused soap that coaxes out shine and protection. A gentle towel dry prevents water droplets from leaving spots, and a tire shine leaves vehicles with the glistening effect brighter than the last time they drove through a jewelry-store display case. The complete 20-minute wash also includes an interior vacuuming, as well as a cleaning of the dash, doors, and windows.

Car Pretty’s complete three-hour detail treatment expands the wash’s basic cleanse with a clay-bar treatment that extracts tar, busts grease, and reveals which dents were filled in with melted jawbreakers. The team attends to intricacies that include door jambs, wheel wells, and moldings and applies a premium glaze to ensure a glossy finish. The detail concludes with a deep cleaning of all interior surfaces, as well as a complete engine cleansing that eliminates evidence of roasting whole turkeys on the manifold.
