Abstract

The present invention relates to a process, an installation and an acidic gel solution (2) for pickling of metal articles (1), in particular barrels (1a) for beverages. The articles (1) are dipped into an acidic gel solution (2) to be subsequently immediately drawn out thereof. The acidic gel solution (2) remains on the surfaces of the articles (1) that are temporarily laid in a waiting station (5) over a predetermined time during which the acidic gel solution (2) removes oxides, salts and other organic or mineral substances from the surfaces of the articles (1). Subsequently, the acidic gel solution (2) is eliminated by means of a washing step also taking away the impurities removed from the above mentioned surfaces.
