<p>[QUOTE="WuntBeDruv, post: 24898349, member: 115520"]Right, but you do apply washing up soda and then put the coin in an oven to 'remove moisture' - which is fine except that the instant you remove it from the oven the moisture levels are back to whatever the humidity of the room is, which means that the corrosion triangle then is complete again since active corrosion if left untreated only requires oxygen and a relative humidity of +35% to continue eating into the metal. That's why the corrosion has to be first treated chemically, then placed in an environment totally devoid of oxygen and moisture followed by lacquer sealing while in that environment . No oxygen, no moisture and proper dry storage equals the arresting of active corrosion. With respect, I personally doubt those things can be achieved securely with household goods and a kitchen oven. However, I'm an open minded man - change my mind! <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
