<p>[QUOTE=&quot;desertgem, post: 570428, member: 15199&quot;]Don&#039;t use the coin dip. If the acetone is contaminated ( maybe the coin itself) , it may deposit a thin film on the coin as it evaporates. Try holding the coin vertically and pour some &quot;pure&quot; unused acetone over it, and hold it vertically until the acetone on the coin evaporates. Whole process should take just a few seconds. You can collect the acetone in a clean glass container, and if the haze was removed, discard it or label it accordingly as contaminated. Pure acetone itself will not cause the haze.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
