<p>[QUOTE=&quot;GDJMSP, post: 1886088, member: 112&quot;]MS70 works quite well just by dipping and rinsing (swishing around) the coin, in some cases. In other cases it will hardly do anything at all. For example, if you have a modern Proof coin that has haze on it, rinsing in MS70 will remove the haze (the haze may come or may not come back later). But if you had a well circulated coin covered with dirt and grime, rinsing in it won&#039;t do much. And since MS70 is caustic it&#039;s not exactly a good idea to let coins soak in it. </p><p><br /></p><p>As for the massaging with a Q-tip, yeah I&#039;m definitely against that idea. But the makers of the product tell you to do that because they know it won&#039;t do much to dirty coins if you don&#039;t. And they want to think their product works so you will buy more. It&#039;s the combination of the product and the rubbing that works. But rubbing a coin, and make no mistake using a euphemism like massage doesn&#039;t change anything you are still rubbing the coin, has consequences. Those consequences are that the rubbing will leave traces, light scratches and or hairlines.</p><p><br /></p><p>Now a some folks are gonna say - I&#039;ve done it and I can&#039;t see any - well, just because you don&#039;t see them doesn&#039;t mean they aren&#039;t there. They are there, dirt and grime has grit in it and any time you rub grit around on a coin it&#039;s going to leave traces. On circulated coins it&#039;s hard to see those traces because they are mixed in with all of the other light scratches, hairlines, and contact marks that circulated coins get in the course of normal circulation. And adding more of them will always make it worse. On uncirculated coins the effects of rubbing are for most easier to see, but there will still be some who say I don&#039;t see any. But they are going to be there because luster is so fragile. Wipe luster with anything and it leaves traces.</p><p><br /></p><p>Also, it is a good idea to do a distilled water rinse after using MS70 so as to remove all residue of the caustic product. Then stand the coin on edge on a soft towel and let it air dry for 24 hrs. Do not pat dry as is often suggested.</p><p><br /></p><p>Bottom line, MS70 is like distilled water, acetone, or even coin dip in that it should be used to do some things and not used to do other things. </p><p><br /></p><p>And Bud, feel free to quote.[/QUOTE]</p><p><br /></p>
