I should've said "the" return, not "our" return; didn't mean to imply that you weren't the one steering us back.
Still, any attempt to retrain people is probably not going to be affective. <== this is the troll icon
The change in toning doesnt haopen Everytime. This was after my first cleaning with olive oil, toothpick. First coin was very superficial took 15 minutes. 2 cleanings as i missed 1 small spot. Pics after 1st cleaning. While the reverse had no problems i did notice a beautiful DDR. 2nd coin i never thought i could get. I believed ate into the metal. After that usual if you can remove the blue green you find pitting. I was very fortunate on this one. As well as lucky i did not scratch the coin by using metal to dislodge some areas as wood is not strong enough when the corrision is advanced. Pics are after 1st cleaning i gave it 2. Its not a miracle romover but ir sure helps make a big difference in appearance. Caution using metal with olive oil very easy to slip n scratch the coin. I have on others 2x. Take extra care n patience. I rarely ever use metal unless want to risk it.
