  Electrolysis is, by definition, the removal of human hair. I have seen many slabs with hairs, dust, and other foreign objects within the holder. Perhaps this is a process whereby hairs are removed from inside the holder?

  There was a dealer that was telling people that PCGS used electrolysis on modern silver coins as part of their restoration service. He was saying it would help prevent spotting on the coins. As far as I know PCGS doesn't disclose what processes they use for restoration, but from what I understand electrolysis would damage the coin. Maybe someone at PCGS can confirm?

  It's pretty obvious the nomenclature is wrong here.
  
  
  
  I could see an "electrolytic" treatment could be employed. I am just guessing, but if the coin were made an anode in a silver plating bath, any current applied would relatively uniformly (if done right) remove a small amount of silver from the surface. It could also be an anode in a cleaning bath which is simpler.
  
  
  
  Would be an interesting experiment for me to undertake as I have plating experience, but alas, I no longer have access to proper equipment and chemicals....

  Electrolysis can be used to remove rust from iron via a battery or battery charger. It can also be used to remove corrosion from dug coins. Compared to mechanical cleaning methods, it is relatively mild if done correctly. When used on dug copper, it often will leave the coin looking worse as it will reveal all of the corrosion pits in the coin's surface.

  it may work for the bikini line of walking lib halves, standing lib quarters, and perhaps 20$ saints

  regardless of how many posts I have, I don't consider myself an "expert" at anything

  As far as I know no one has found a cure or treatment for Milk Spotting on Eagles so they just quit giving a warranty for it.
  
  So I think this guy is just blowing smoke and not spelling it correct.

  Electrolysis will remove some surface material... likely affecting (either totally or to some degree) any luster present. Have never heard of it removing milk spots. Cheers, RickO
