<p>[QUOTE=&quot;mrjason71, post: 2908612, member: 90347&quot;]Gotcha.It was assumed i was using the term &quot;dip&quot; incorrectly. I assumed it would be taken to mean what it means. I see this is a big pet peeve of SuperDave&#039;s (and I&#039;m sure of others) and he&#039;s big on people using the term incorrectly--lurking and eager to pounce on its misuse. He loves pointing out it has thiourea and that the problem with all the fools is they just don&#039;t know when to use it. Its good to have dip police but they musn&#039;t be so patronizing. How does not publishing your masterwork on conservation spare the world anything? He could write a Chapter One called &quot;What Coins You Should or Shouldn&#039;t Dip&quot;. Imagine how helpful that would be. Obviously not trying to be helpful. Imagine the audacity of saying that by you not publishing your work you have somehow helped the world...I really just cant wrap my mind around that.</p><p><br /></p><p>As opposed to you, GDJMSP. I have learned so much from you (and some others) directly and by reviewing your history of posts. Invaluable. Thank you. I owe you a great debt. And to the fellow who PM&#039;ed me and really went into great depth regarding dipping (with a solution consisting of thiourea and an acid) successfully. Is the point of this forum not at least partially to teach? Or is it just to thump one&#039;s chest?</p><p><br /></p><p>I mean i said &quot;junk coins&quot;, so why would he say &quot;I sincerely hope these are coins with no numismatic value&quot;. </p><p><br /></p><p>I said &quot;I&#039;ve found that dip leaves some dirt&quot;, so why would he say &quot;If all you&#039;re looking at is &quot;tarnish&quot;.</p><p><br /></p><p>And this is worth repeating:</p><p><br /></p><p>&quot;It&#039;s threads like this one which prove to me the fundamental wisdom of having decided to keep most of my conservation methods to myself, rather than publishing them as I originally intended a couple years ago. Anyone can learn and apply a scientific process, but it seems very few can cogently decide <i>when to apply it</i>.&quot;</p><p><br /></p><p>What the ____?</p><p><br /></p><p>Absurd.</p><p><br /></p><p>I needed to get that off my chest. My (thiourea/acid based) dip procedure was developed over lots of trial and error and then honed with the help of someone here privately and I don&#039;t know if its ok to divulge any of the methods he suggested but I assure you its all the standard stuff that is freely and frequently mentioned here: pre-dip prep (DW, Acetone, etc), air dry on edge (where did I get that?), diluted dip no longer than a few seconds, neutralize, rinse.</p><p><br /></p><p>Like I said Ive left JUNK coin in dip for a minute and this mysterious substance that is not tarnish/toning remains. And Coin Care did not remove it. I agree it is not something I want to use much anymore and definitely not as a &quot;cleaner&quot;...[/QUOTE]</p><p><br /></p>
