I've been putting the nicer coins I find in an acetone bath, rinsing in distilled water and air-drying before putting them in a flip as well. I was just going to add that if you have any raw coins that are VERY valuable, you might want to have them professionally conserved. PCGS and NGC will do it at a reasonable price before grading (if you ask). It looks like ANACS will do it for cheap as well.

Vinegar is a mild acid - it'll definitely clean a coin but in the process will irreparably damage the surfaces. That will significantly reduce the value of any collectible coin.

I don't clean my coins, but if they need to be a little more 'shiny' I simply use a fine micro fiber cloth and go over one very gently. If it does not achieve what I desire after a minute, then I stop. No harm.  |

Why would you think making a coin "a little more "shiny"" improves its value?
That microfiber wipe is removing surface patina, and before long your coin will be worse than before.

 to the CCF Well, you have stirred the CCF hornets nest for sure.  I hope you get the point that using chemical or abrasive methods to clean a coin in hopes of improving it actually robs any value it might have and is considered a serious offense by even the most basic knowledgable collector. Don't clean your coins.  Take a look at my other hobby ... http://www.jk-dk.art |

So NaCl plus C6H8O7. What can be the most worst for Cu coins? Oh it is the Potassium cyanide. The combination of those result in: Chlorhydric acid, Nitric acid and more.
This combination is so powerful then will attack any element in the Cu alloy.
Please can you give me the link of this YouTube? I want to know who was this idiot.
