Car wash express tunnels typically feature a streamlined design that guides vehicles through a series of automated cleaning processes. As cars enter the tunnel, they are prepped for washing with high-pressure water sprays that remove loose dirt and grime. This pre-wash stage is crucial, as it prevents scratches during the main washing phase. Following this, the vehicle travels through a series of soft cloth wash brushes that gently yet effectively scrub the surface, ensuring that every nook and cranny is attended to without damaging the paint.
