Don&#039;t pretend to be either. And I cannot argue with you about chemical reactions. But there is a problem when you tell people that dipping copper coins in acetone will not and cannot hurt them. Because it does sometimes.</p><p><br /></p><p>It doesn&#039;t matter that the acetone is reacting with this on the coin, or that on the coin. All that matters is that it is in fact reacting with something, and only on copper coins, and that the coin can turn weird colors as a result of being dipped in the acetone.</p><p><br /></p><p>I&#039;ll grant you on silver, nickel, gold - you can dip your coins in acetone from now until the cows come home and there is never any reaction, the coins never turn weird colors afterwards. And the worst thing I have ever seen is that the coin sometimes gets a whitish cast to it if you don&#039;t dip it in distilled water afterwards. As both of you know, I&#039;ve made recommendations to literally thousands of people to dip their coins, and yes even copper coins when the situation warrants it, in acetone. I have nothing against acetone !</p><p><br /></p><p>But to pretend, or to tell people that it is 100% safe to dip their copper coins in acetone because copper cannot react with acetone - is just plain foolish. The people need to understand that there is some risk if they do that. It doesn&#039;t matter if the acetone is, as you say, not at fault. All that matters is the end result of it being done. Face it, it happens. And to state it doesn&#039;t happen, or cannot happen, is ridiculous because it does.[/QUOTE]</p><p><br /></p>
