<p>[QUOTE=&quot;IdesOfMarch01, post: 2784059, member: 39084&quot;]Based on my recollection of chemistry, as well as research on the Internet, it appears that lemon juice will have little if any corrosive effect on pure silver. </p><p><br /></p><p>Lemon juice&#039;s acidity is due to its citric acid content.&nbsp; Citric acid is present in lemon juice in a very low percentage -- too low to create any chemical reaction with pure silver.&nbsp; From what I could find online, even prolonged exposure of silver to low-acidity lemon juice will not cause the silver to corrode.</p><p><br /></p><p>The citric acid will help dissolve other deposits on the coin, and maybe that&#039;s why coins treated with lemon juice can end up looking pitted.&nbsp; But in these cases, the pitting was probably underneath the deposits to begin with, and thus it&#039;s a question of whether you want a clean but pitted coin, or a deposit-laden but non-pitted coin.</p><p><br /></p><p>The OP&#039;s result looks (literally) wonderful, as in: I&#039;m full of wonder about how the result could possibly look that good with such a mild and simple cleaning regimen.&nbsp; In my opinion, even though the uncleaned coin was of a desirable type, it was well worth the risk of damage to improve it.</p><p><br /></p><p>Very, very well done![/QUOTE]</p><p><br /></p>
