Metal cleaning and pickling services are available in Adel. This is a surface treatment for the metal, which is done to remove stains, inorganic contaminants, rust or scale. This is usually applied to steel, other ferrous metals, copper, and aluminum alloys. The "pickling" is done using pickle liquor, which contains strong acids. The most common acids used are hydrocholic acid and sulfuric acid. Constant usage of the metal or the metal surfaced machine leaves it discolored, or oxidized. This treatment removes the oxide layers, as well as stains. It is important to note that acid concentrations and solution temperatures have to be regulated to pickle in a safe manner. After usage, the liquor and the waste suspended in it is usually neutralized with lime and put in a landfill.
