but the difficult thing to explain is just exactly what "cleaning" entails (should or needs to)
As copper and lead are for all intents and purposes corrosion resistant they themselves are not the problem.
The galvanic process you refer is just a comparison of rates of corrosion of two dis-similar metals in contact in an electrolyte
The key to any corrosion is the presence of an acid/electrolyte/solution (moisture, water, acid residue, vapour etc etc)
remove it and you have no corrosion
