The most common pickling bath for Iron and Steel is composed of a 10-20% Sulfuric acid solution. Brass is bright cleaned with a mixture of sulfuric acid and Nitric acid. The red cuprous oxide stains on copper and copper alloys are removed with a sulfuric acid solution mixed with Sodium dichromate. Aluminum can be cleaned with a Framanol solution that contains Chromium phosphate and Triethanolamine. Acid baths work by chemical reaction of the acid with the surface of the metal.
