<p>[QUOTE="Just Carl, post: 119357, member: 4552"]If it is a necessity that you feel you have to remove dirt from a coin you should first try to assertain what exactly the dirt is composed of. If in fact it is just dirt, then the water you tried should have removed some or all of it. If the dirt is not dirt but a toning or metallinc compound formed due to exposure to the elements, then any removal will take some of the metal away with it. If you are really curious as to the many methods of this removal process, I suggest you find a relatively inexpensive coin and try some of the following:</p><p>Emerse the coin in a liquid called Acetone available at any hardware store. However, this is not a pure Acetone substance and will leave a residue after evaporation.</p><p>Emerse the coin in dish soap and warm water and then rince with distilled water and blow dry.</p><p>Emerse the coin in battery acid and allow to sit there for a few weeks. This can be either purchased at a auto</p><p> parts store or you can steal it from a neighbors car battery. </p><p>Find a lady with Tarn-X jewelry cleaner and put the coin in there. Don't tell her because the coin will</p><p> contaminate the solution.</p><p>Heat with a blow torch. This will actually melt the dirt off. Don't hold in your hand during this process.</p><p>Lay the coin on top of an M-80 and light. Won't clean the coin but will get rid of it for you. </p><p>Wet the coin, rub with a Brillo Pad until a nice shine is accomplised. bow dry so as not to leave spots.[/QUOTE]</p><p><br /></p>
