<p>[QUOTE=&quot;gsimonel, post: 4654890, member: 82549&quot;]Soaking coins in water will remove any dirt that is still on them. I hate to be the one to throw cold water on your coin-soaking project, but all the coins you&#039;ve received have already been cleaned down to bare metal. You are unlikely to see any improvement in them by soaking them in tap, spring or distilled water.</p><p><br /></p><p>The two coins that you are soaking still have some encrustation on them. Soaking will not remove this. You&#039;ll need to use a harsher treatment, such as electrolysis. (Some members prefer to use lye, but I don&#039;t recommend this.)</p><p><br /></p><p>The good news is that your are unlikely to do any serious damage to the two coins that you are soaking because they are common types and already pretty well worn, so this might be an opportunity for you to experiment with using electrolysis to clean coins. Then, if you get some legitimate crusties--coins with so much encrustation on them that the seller really has no idea what is under the encrustation--you&#039;ll know how to clean them with electrolysis and what to expect from the process.</p><p><br /></p><p>Here&#039;s some information about electrolysis: </p><p><br /></p><p><a href="https://department.monm.edu/classics/COINS/data/cleaning/electrolysis.htm" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://department.monm.edu/classics/COINS/data/cleaning/electrolysis.htm" rel="nofollow">https://department.monm.edu/classics/COINS/data/cleaning/electrolysis.htm</a></p><p><br /></p><p>However, this site says to use salt as your solute. Don&#039;t use salt. It&#039;s too corrosive. Use sodium cabonate (Arm &amp; Hammer Washing (not baking) Soda) instead. You&#039;ll find it in the laundry detergent section of your grocery store.[/QUOTE]</p><p><br /></p>
