Abstract

A process for the removal of corrosion products on tin and tin alloy surfaces by electrolytic cleaning using natural seawater, which comprises removing loosely adherent corrosion products by known surface cleaning means, such as brushing the work piece, characterised in that subjecting the work piece to electrochemical treatment with cyclic polarity reversal, in pre-cleaned natural seawater as electrolyte such as herein described, at a pH ranging from 6 to 9, at a current density in the range of 600 A/m2 to the maximum threshold value, wherein the said work piece is initially cathode and subsequently anode with reference to an auxiliary electrode of an inert anode material
