<p>[QUOTE=&quot;oz_in_ohio, post: 2975407, member: 89534&quot;]Take no notice of that...Acetone is used to drop stamps in when wanting to detect a watermark and to make the wmk stand out clearer. Then when the stamp is taken out of the solution , it can be picked up with tweezers, waved in the air a few times and it will dry immediately...IT WILL NOT DISTURB THE GUM so no need paying a proffessional to identify the WMK... </p><p><br /></p><p><b><span style="color: #ff0000">Personally i use olive oil and a toothpick to clean coins if it is necessary</span></b>....</p><p>Oil does not take away the coins color and a toothpick does not scratch the coin as it is wood and wood does no harm to metal...To place the olive oil on the coin ( if you dont want it in salad lol ) get a cotton bud or cotton swab and saturate the cotton in the oil...Then saturate both sides with the oil and wait 2 hours or so for the oil to penetrate the dirt and grime so it lifts easier. Have the coin stand up on the rim so both sides get air to it... Then when the 2 hours or so has passed , with a toothpock go through all the lettering and finer points to lift up the grime etc...Then redo the oil again but with a fresh cotton swab, take what bits are left in the lettering and remove it all.. I might suggest you practice on really cheap low graded coins with vertigris to get experience....Just remember if the job is not done properly, a professional will be able to notice.</p><p>I personally use a jewellers loupe at 10 times magnification to check my work.</p><p>These can be purchased under $20 from any jeweller supplier or coin shop.</p><p>The olive oil repels water so i would stay away from using water... On top of that, the oil does not remove lustre and coins color but water does.....Now with the acetone, i like the smell of it better than aeroplane model glue so use it for that...heh heh heh... BUT SERIOUSLY ONE SHOULD NEVER EVER CLEAN A COIN!!!! That is why there are so many grades...It is also stated in many books that one should not clean coins but rules are made for breaking...correct???..I have scanned the page for you out of my reference book. if you are still unsure, go to the library and check for yourself....Lots of luck[ATTACH=full]730905[/ATTACH][/QUOTE]</p><p><br /></p>
