There are, however, certain acid-based materials which can primarily be construed as cleaners. One such type of material is used in the cleaning of aluminium cans prior to treating and lacquering. Such cleaners are normally based on sulphuric or phosphoric acid, with, generally, additions of hydrofluoric acid and surfactants. These materials are sprayed on to pre-formed cans to remove the lubricant used during the can-forming operation. The fluoride is present to enhance the removal of fines of metal swarf in the cans as well as to remove the oxide film. 

Care must be taken here not to confuse acid cleaners with the high-strength, phosphoric acid-based chemical polishes and chemical brighteners, which are used specifically to obtain the surface finish which such materials produce. Also in the category of acid cleaners could be considered the lightweight alkali-metal phosphating cleaner-coater solutions, but a discussion on such materials is best left to specialist publications on metal pretreatment chemicals. 

So far, all discussed examples of acid-base reactions used to construct coordination polymers involve soluble metal salts as precursors. Flowever, as mechanochemical reactivity is independent from the solubility of reactants, the use of slightly soluble but cleaner and readily available carbonate or oxide reactants is also possible. With oxide reactants, the highly basic nature of the oxide ion provides a strong driving force for the... 

Acid cleaners based on sulfamic acid are used in a large variety of appHcations, eg, air-conditioning systems marine equipment, including salt water stills wells (water, oil, and gas) household equipment, eg, copper-ware, steam irons, humidifiers, dishwashers, toilet bowls, and brick and other masonry tartar removal of false teeth (50) dairy equipment, eg, pasteurizers, evaporators, preheaters, and storage tanks industrial boilers, condensers, heat exchangers, and preheaters food-processing equipment brewery equipment (see Beer) sugar evaporators and paper-mill equipment (see also Evaporation Metal surface treati nts Pulp). 

Ammonia is used in the production of several chemicals to make nylon adipic acid, hexa-methylene diamine, and caprolactam. It is used to treat metals in annealing, nitriding, and descaling. Ammonia is an excellent fungicide that is used to treat citric fruit. It is also used to increase the nitrogen content of crops used as feed for livestock. Ammonia dissolves readily in water to produce aqueous ammonia or ammonium hydroxide NH + 2 < > NH4+(a(i) + OH (ahydroxide ions shows that ammonia acts as a base in aqueous solution. Concentrated aqueous solutions contain 35% ammonia. Household ammonia cleaners contain between 5% and 10% ammonia.

Acidic, Cifvi) solutions may be used as cleaners or etchants for metals (e.g. Cu) and plastics, e.g. ABS acrylonitrile/butadiene/styrene. In the case of metals, the Cffvi) may be used in order simply to clean the metal, etch the surface or completely remove a metal coating. The etching of plastic substrates is a key step prior to metallizing epoxy based laminates during the production of printed circuit boards.
