Speedway Express' all-purpose car-care facility tricks cars out of their dirt collections during three-minute express washes. During the All-Star wash, soapy solutions storm the car frame, de-gunk the wheel wells, and flush the underbody in preparation for triple-foam polishes, which teach paint how to reach its full potential. Finally, ultra-high-speed dryers and a spot-free finish stamp the frame with a clean seal of approval. The Victory Lane wash extends the All-Star service with splashes of tire shine and a smothering layer of 30-day polymer protectant. Each express-car-wash option includes a free visit to the vacuums, where drivers can fish out any debris that isn't bolted to the vehicle's floor.

The 20-minute Super Speedway wash picks up where the Victory Lane wash leaves off, performing a full interior vacuum, wiping windows, and conditioning the dash and console areas until they're as uncluttered as an a capella band's tour bus. After clearing doorjambs of grime and hand drying the car, technicians take time to clean wheels and shine tires by hand, then finish up by drying off the car and sending it out to roam the nearby roads and runways.
