Abstract
This invention teaches the development of a chemical reagent useful as an aluminum brightening bath. The reagent's composition is primarily wet-process phosphoric acid to which has been added small quantities of nitric acid, copper, and optionally traces of several other substances. The reagent does not require expensive removal of the natural impurities found in wet-process phosphoric acid.
