Abstract

A pickling fluid for cleaning metal surfaces, more particularly for preparing aluminium and aluminium alloys for soldering or for cleansing aluminium cooking utensils, consists of an aqueous solution of orthophosphoric acid, nitric acid, and acetic acid. Formic acid may be employed in addition to, or instead of, acetic acid and in the same proportions. The bath may consist of the following parts by weight:ortho-phosphoric acid 60-90, nitric acid 20, acetic acid 5-10, and water 250.
