<p>[QUOTE=&quot;John Burgess, post: 5292931, member: 105098&quot;]Acetone can remove dirt, gunk, oil and grime, new fingerprints even, it doesn&#039;t remove tarnish/toning. </p><p><br /></p><p>The hazing can be tarnish (the beginning of toning) and if so, acetone won&#039;t remove it. as stated a coin dip like &quot;MS70&quot;&nbsp; would remove it but it is a mild corrosive, so follow directions and when in doubt leaving it alone is a better option. Dipping a coin too many times will destroy it&#039;s luster also. </p><p><br /></p><p>Another thing for silver is milkspots. As far as I am aware, you can&#039;t get rid of them without damaging the coin, they will return even after dipping but they will be less noticeable for awhile. this also show as a spotty haze on a coin, almost like a liquid (milk) spilled on it and dried.</p><p><br /></p><p>Best to know what you can and can&#039;t do with various liquids, products, chemicals and test on something you don&#039;t care about instead of wrecking something you do care about by going too far with something a product can&#039;t do. </p><p><br /></p><p>Distilled water will do about what acetone will do, it&#039;s the same pH, but it&#039;s not a solvent like acetone is, so results may improve with acetone over distilled water, I like distilled water as the least intrusive first step, it&#039;s just water with no minerals, fluoride or chlorine, no impurities and a neutral pH. you can let it soak and air dry without spotting. </p><p>&nbsp;Besides acetone, I&#039;ve also heard toluene or xylene will work on things that acetone doesn&#039;t touch as they are different solvents. but again, they don&#039;t remove tarnish/toning.</p><p><br /></p><p>if the haze is tarnish/toning, a &quot;coin dip&quot; will likely be needed to remove it, but you should practice this and do it the least amount possible to get the desired effect, if it messes up flow lines or luster, from leaving it too long, or dipping too many times,&nbsp; you can&#039;t get that back again.[/QUOTE]</p><p><br /></p>
