Each time a vehicle purchases a single car wash, it will automatically earn 1 loyalty point, tracked through the vehicle’s license plate. Once the same vehicle has earned 5 loyalty points (by purchasing 5 single washes), it will receive a FREE Diamond Ray Car Wash—our top-tier wash valued at $24—on its next visit. No sign-up is required! Just visit your local Glide Xpress Car Wash, purchase a single wash, and your loyalty points will be automatically tracked.
