While there are many types of car washes, most fall into the following categories:
- Hand car wash facilities, where the vehicle is washed by employees.
- Self-service facilities, which are generally coin-operated, where the customer does the washing, including "jet washing".
- In-bay automatics, which consist of an automatic machine that rolls back and forth over a stationary vehicle - often seen at filling stations and stand-alone wash sites.
- Tunnel washes, which use a conveyor to move the vehicle through a series of fixed cleaning mechanisms.
- Chemical car wash, also known as waterless car wash, uses chemicals to wash and polish car surface. Thought to have originated in Australia and claims to be an eco-friendly car wash method.
- Steam car washes use a jet of steam and micro fiber towels, some include detergent injection. Known to have originated from South Korea, steam car washes have been especially popular as a low-investment, eco-friendly car wash solution in Asia, Middle East and Europe thanks to its sanitizing features and mobility.
- Mobile Car Washes, often also serving as mobile detailing systems, which carry plastic water tanks and use pressure washers. Sometimes these systems are mounted on trailers, on trucks, or in vans. Generally these operators also have a generator to run a shop vac., buffers and other tools as well.
Mechanized car washes, especially those with brushes, were once avoided by some meticulous car owners because of the risk of damaging the finish. Paint finishes have improved as have car washing processes, and this perception of vehicle damage is much less today. However, this perception was the motive behind the rise of facilities utilizing "brushless" (cloth) and "touch-free" (high-pressure water) equipment, as well as modern "foam" washing wheels made of closed cell foam.
In today's modern car wash facilities, whether tunnel, in-bay automatic or self-serve, soaps and other cleaning solutions used are designed to loosen and eliminate dirt and grime. This is in contrast to earlier times, when hydrofluoric acid, a hazardous chemical, was commonly used as a cleaning agent in the industry by some operators. There has been a strong move in the industry to shift to safer cleaning solutions. Most car wash facilities are required by law to treat and/or reuse their water and may be required to maintain waste-water discharge permits, in contrast to unregulated facilities or even driveway washing (at one's home), where waste-water can end up in the storm drain and, eventually, in streams, rivers and lakes.

Famous quotes containing the word categories:
“Of course I’m a black writer.... I’m not just a black writer, but categories like black writer, woman writer and Latin American writer aren’t marginal anymore. We have to acknowledge that the thing we call “literature” is more pluralistic now, just as society ought to be. The melting pot never worked. We ought to be able to accept on equal terms everybody from the Hassidim to Walter Lippmann, from the Rastafarians to Ralph Bunche.”
—Toni Morrison (b. 1931)
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
“All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
