<p>[QUOTE=&quot;IdesOfMarch01, post: 2209700, member: 39084&quot;]I should add that you can also stop bronze disease by removing the chloride ions from the coin but this is very difficult.&nbsp; To quote Wikipedia:</p><p><br /></p><p>&quot;<i>As it relies upon the presence of chlorides, water, and oxygen, the absence of one of these three halts the progress, although any damage done is irreversible. Treatment for the condition typically involves physical removal of the chlorides (through scrubbing), chemical or electrochemical removal, and then isolating the object from oxygen, water, and future chloride contamination using an airtight container or a wax coating. These treatments may also remove any patina, loss of which is often seen as undesirable to collectors and conservators but is preferable to loss of the object.</i>&quot;[/QUOTE]</p><p><br /></p>
