Abstract: A chemical metering system for providing efficient access and replacement of chemical metering devices. The chemical metering system generally includes a chemical injector, a first tube fluidly connected to the chemical injector, a second tube adapted to be fluidly connected to a chemical supply, a releasable tube coupling removably and fluidly connected to the first tube and the second tube, and a metering device is adapted for controlling a flowrate of liquid chemical into the chemical injector from the chemical supply. The metering device is accessible for repair or replacement by removing the releasable tube coupling from either the first tube or the second tube for efficient access and replacement of the metering device.

Abstract: The present invention provides a metal brightener and surface cleaner, which provides significant etching of aluminum and other metals, without detrimentally affecting other surfaces such as painted surfaces, glass, rubber and plastic. The inventive composition is especially suited for aluminum brightening for large vehicles, and may be utilized in an alkaline step of a multi-step vehicle wash. One of the exemplary compositions includes an alkali metal hydroxide; a polycarboxylic acid; an alkali metal salt of an organic acid; a first, amphoteric surfactant; a second, betaine surfactant; and a third, nonionic surfactant.

Abstract: A fluid mixing and blending system employs a fluid mixing passage having two or more discrete, individually controllable mixing elements located along the mixing passage. The use of a single mixing passage with multiple mixing elements, such as venturis, assures consistent and precise mixing, with a system which is economical to produce.
