The customer next encounters tire and wheel nozzles, which the industry calls CTAs (Chemical Tire Applicators). These will apply specialized formulations, which remove brake dust and build up from the surface of the wheels and tires. The next arch will often be wraparounds, usually made of a soft cloth, or closed cell foam material. These wraparounds should rub the front bumper and, after washing the sides, will follow across the rear of the vehicle cleaning the rear including the license plate area. Past the first wraps or entrance wraps may be a tire brush that will scrub the tires and wheels. This low piece is often located beneath a mitter (the hanging ribbon-like curtains of cloth that move front to back or side to side) or top wheels. There may also be rocker panel washers which are shorter in size (ranging in size from 18 inches (45 cm) up to 63 inches (160 cm) tall) that clean the lower parts of the vehicle. Most rocker brushes house the motor below the brush hub so they don't inhibit cloth movement and allow the brush to be mounted under a support frame or below a mitter. Some car washes have multiple mitters, or a combination of mitters and top brushes.
After the mitter or top brush(es) the car may pass through a second set of wraparounds. This may also be where high pressure water streams are used to clean difficult to reach parts of the vehicle. The car generally passes over an under carriage wash and/or has high pressure nozzles pointed at it from various positions. Next may be a tire spinner, high pressure nozzles angled specifically to clean wheels and tires. After the several wash stations the vehicle may go through triple foamers, usually red, blue, and yellow, although colors can be customized with higher end chemical suppliers. The triple foam process includes special cleaners as well as some protective paint sealant.
Some washes have multiple rinse stages, usually offering a protectant as an option.
Protectants vary by manufacturer. Near the rinse is where a tire shining machine is often installed, which is designed to apply silicone tire dressing to the tires. This application makes the tires look good (new, and glossy) and preserves the rubber. Next the vehicle is treated with a drying agent and a final rinse. Many carwashes utilize a "spot free" rinse of soft water that has been filtered of chlorine and sent through semi permeable membranes to produce highly purified water that will not leave spots. After using spot free water, the vehicle is finished with forced air drying, in some cases utilizing heat to produce a very dry car.
