[QUOTE="GypsyGoldAu, post: 311486, member: 5873"] I would use that as a 'finish' process after cleaning,..but yeah, your on the right track. If you have some nickel around it's a better way to go, though you can't undo the 'leeching' that has already occurred, so best to draw as much out now as possible, before trying to seal-coat it with nickel...imo. I just used 'copper' as the cathode example, as i wasn't sure what you had used, but many do just use copper in a homemade bench system. You will have to determine if your set-up is 'cleaning' the coin, or 'attracting' the copper from the cathode first. As i said, a switch in polarity will reveal which is occurring. Remember the (+)Positive electrons (Anode) are 'attracted' to the (-)Negative (Cathode) so goes the 'flow' of your suspended solution. Also rinse the anode & cathodes when changing polarity/solution/cathode to minimize contamination. Hope that makes sense..i'm an operator and not a teacher lol... ]:D [/QUOTE]
