<p>[QUOTE=&quot;singig, post: 4775278, member: 93672&quot;]For this type of cleaning I&#039;m using vinegar(or lemon juice) , both are less aggressive than others chemical acid solution on the market. At the beginning I keep the coin in vinegar for short intervals 30 minutes/1 hour to see how it reacts , if the results are good I extend the time interval to 2 hours .....After each interval I use bamboo sticks to remove the encrusted dirt , plus brushed under water. I repeat the process for as long as necessary. At the end , is very important to keep the coin in water for at least 3-4 days (change the water each day) to remove any acid from the coin surface, its pinky colour will fade gradually. I do not add wax immediately, I wait for a while.</p><p>Don&#039;t forget <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />, you are taking a risk cleaning this coin , think two times before do it.</p><p><br /></p><p>Today I will post an example with a uncleaned lot of coins(5) from the same period, cleaned three years ago , you will see how their colour has changed. </p><p>[ATTACH=full]1162591[/ATTACH][/QUOTE]</p><p><br /></p>
