Propyl bromide, the main ingredient, does easily turn acidic with water. The other ingredients seem to be relatively safe for metal ( the oxygenated hydrocarbons could be a mix of acetone like chemicals. I agree with Doug that advertising generally says what they hope you believe.&nbsp; Looking fairly at it, the use of this compound used properly would probably not damage the coins, but I prefer acetone if needed myself, and I am relatively conservative ( pun) and&nbsp; I feel safe using only a few chemicals for my coins that I have experience. IMO.</span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000">Jim</span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p><p>[/QUOTE]</p><p><br /></p>
