<p>[QUOTE=&quot;poker_prof_AA, post: 163471, member: 6698&quot;]When a coin has spots left on it, a REDOX reaction has occured.&nbsp; The silver however appears lower on the REDOX table than pure water so the reaction cannot occur without the aid of electricity, and no I don&#039;t have my coin hooked into the wall blasting it with electricity.&nbsp; If the coin is quickly soaked with pure water nothing will happen.&nbsp; If it is soaked for a long time the ions from the **** on the coin <b>may</b> dissolve in the water creating a REDOX reaction which in turn will oxidize the surface of the silver coin.&nbsp; <b>All i want to know is, is there a material that I can use that will not create scratch marks on the coin</b>, I already tried Q-tips but they left tiny hairlike marks when magnified.&nbsp; If anyone can answer this question I would appreciate it.&nbsp; Any help is great.<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie6" alt=":cool:" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
