<p>[QUOTE="desertgem, post: 1660550, member: 15199"]Yacorie, are you specifically speaking of the greenish dots under the '8' of the date? That could be the corrosion where PVC plasticizers /acids were once but the pvc component ( essentially colorless) would have been removed in minutes by the acetone. Corrosion or surface damage stays. Since you have immersed it in acetone so long, when removed and dried, any moisture still on/in corrosion centers is gone. Proper storage will prevent it from increasing. Dipping is a possibility with all of the cautions Doug mentions above. Although it is not mentioned on the 'dip' bottles, it is just a chemical solution and dilution of a 1/2 ounce with 5 or more ounces of distilled water will slow down any reaction by a factor of approx. 10. Thus you can dip and rinse/observe and redip to stop when it is at a point you can accept. Yes things could end up worse, so take that into consideration. Commercial 'Dip' is quite strong, most often too strong, especially for new users of it. IMO.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
