reverse electroplating in water process

Anodic electrocleaningalso uses areversecurrent, which effectively pushes materials away from the workpiece’s surface.Cathodic electrocleaning, on the other hand, though it produces more bubbles, tends to be the less preferable of these two methods, primarily due to the imperfections that can arise from theprocess.

The gold refining forum that I act as a moderator on [ed. note: goldrefiningforum.com] has done much work with the so-called "reverse electroplating" method of gold stripping using concentrated sulfuric acid as the electrolyte. It can be used to strip gold from most anything, including aluminum, without attacking the substrate metal (unless the solution gets too hot).
