A car wash or auto wash is a facility used to clean the exterior and, in some cases, the interior of motor vehicles. While there are many different 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. Known to have originated from Australia and has been well-received as an eco-friendly car wash method around the world, that saves water.
Steam car wash uses steam jet and micro fiber towels. Popular in Asia. A detergent is a material used for cleaning. The term is sometimes used to differentiate between soap and other surfactants used for cleaning. The earliest detergent substance was undoubtedly water; after that, oils, abrasives such as wet sand, and wet clay. The oldest known detergent for wool-washing is stale (putrescent) urine. For the history of soap, see the entry thereon. Other detergent surfactants came from saponins and ox bile.
The detergent effects of certain synthetic surfactants were noted in 1913 by A. Reychler, a Belgian chemist. The first commercially available detergent taking advantage of those observations was Nekal, sold in Germany in 1917, to alleviate World War I soap shortages. Detergents were mainly used in industry until World War II. By then new developments and the later conversion of USA aviation fuel plants to produce tetrapropylene, used in household detergents, caused a fast growth of household use in the late 1940s. Enzyme detergents were made in 1960s. Cleaning products or solutions need to be appropriate for dealing with a variety of dirt. For example, water normally does not work well to remove an oily soil, such as a greasy mess on the stovetop. So, to enhance the power of water a number of ingredients can be added to form a more effective water-based solution. Surfactants, solvents, and chelants mixed with water will improve its ability to dissolve the oily soil. Builders, bleaches, and enzymes can be added to water to chemically change the oily dirt in order to make it soluble in water. The best combination of these ingredients in water will deliver a truly powerful cleaning solution.
Builders:Compounds that adjust pH to optimize cleaning performance and contribute to suspending soils.
Bleaches:Compounds that oxidize and remove soils and lighten the color of stains.
Enzymes:Biological proteins that speed the breakdown of soils.
Surfactants:Compounds that allow cleaning solution to wet surfaces
