<p>[QUOTE=&quot;aviko, post: 132151, member: 5498&quot;]Hi Guys,</p><p>Carl and PyrotekNX - thank you for your replies.</p><p>Here are some results. Since I live in Israel Walmart was not an option but nevertheless I did try some cruel techniques. So from left to right:</p><p>Coin 1: Wad dipped in soap and warm water and then in vinegar. The problem I found is that the green corrosion is more resistant to the treatment so by the time it was gone the nice patina was also gone. What I did notice is that after several minutes the coin (apart from the green corrosion) looked really nice i.e. it looked as new and did not loose its lustre. Since I kept it a while longer in the vinegar it became the ugliest cleaned coin you can imagine.</p><p>Coin 2: Got the same treatment as Coin 1. What I thought&nbsp; was a tape is something totally different. Some kind of nasty stuff was put on that coin some when along its history. Cleaning it revealed the fatal wounds it already had.</p><p>Coin 3: Got the same treatment as Coins 1 and 2. What seemed to be green lines of corrosion are actually corrosion inside some nasty scratches. Again the coin is now suffering from both scratches and also from my cruel treatment.</p><p>Coin 4 (The silver): Was dipped in a dish washer soap and warm water. The results are very good. Some of the dirt is gone (it looks better than the scan) and the coin did not get the polished look cleaned coins usually get. This has to do with Carl&#039;s advice about how to dry it.</p><p><br /></p><p><br /></p><p>So - to conclude.</p><p>I saved one patient (the silver), killed another (coin 1) and found out, after the operation ended, that nothing could be done for the other two (coins 2 and 3). More or less the statistics you would find on any E.R. on hospitals (Just joking).</p><p><br /></p><p>Would love to hear what you guys think. Just to remind you - I am just a beginner and did not mind fooling around on some cheap stuff.</p><p><br /></p><p>Avi[/QUOTE]</p><p><br /></p>
