ABSTRACT:
A touchless car wash composition, that can be made from a concentrate and diluted to use concentration using commonly available service water can comprise an ether amine or diamine in particular a fatty ether amine or diamine. The novel compositions are typically free of hydrocarbon solvents and silicone materials that are common in prior art compositions. The compositions are used in touchless car wash processes in which the materials are sprayed in the form of an aqueous dilute solution to remove soil from the vehicle surface. The aqueous compositions are self removing and very small amounts of the aqueous solutions remain to create water spotting on cleaned vehicle surfaces. The novel compositions of the invention can also contain a variety of other ingredients in a fully formulated system. Such ingredients include rapid dewatering of painted surfaces, improved cleanliness of glass and painted surfaces. A substantial reduction of water spotting and concentrates stability. When used in systems using the direct contact between a brush, the friction between the brush and the vehicle surface is substantially reduced.
