ELECTROCHEMICAL DE‐RUSTING

An interesting electrochemical process for de‐rusting corroded equipment and plant has been operated with increasing success since the war by the London firm of Derustit (Great Britain) Limited. The process removes rust and other surface deposits and completely cleans the machinery or parts treated but does not render the surface corrosion‐resistant. Essentially, therefore, it is a metal cleaning and pre‐treatment process. It can be and has been applied to rusted machinery ranging from ball‐bearings to large locomotive parts, and many large firms and all the Service departments have made use of this means of metal ‘laundering.’
