It's safe for me (hic), not sure about coins! Not safe for me.  As for coins, I agree with what has been said. It is probably okay, but not very efficient compared to acetone. If you are going to buy something, acetone is a better choice than alcohol. |

My problem with alcohol and coins is consuming it and then making purchases I regret  But as for using isopropyl alcohol as a rinse, there shouldn't be much of a problem as long as you let it completely evaporate and ensure that the coin is dry before putting it in a 2X2.

on a lot! That's too funny and ironic..... This is a ebay message from me a couple weeks back: " Retail is my max as of now, $575, may stretch it to $600/$650 if you catch me after a few glasses of wine" Needless to say we made a deal a few nights later |

Napkins seemed like a good thing to me. Sometimes it is difficult to find 70% ethyl alcohol in a pharmacy (people usually try to buy it for ingestion). Similar material is available for free sale. This is a soft cloth impregnated with 70% ethyl alcohol and possibly several other antibacterial substances to disinfect the surface. Quote:
not wipe with anything not even cotton swabs or cotton balls. Why? Sometimes there may be remnants of dirt on the coin that have not yet had time to eat the metal and in this case it is necessary to remove the remnants of dirt and finger marks. Edited by Slerk

I needed a drink last night. I bought a 1 oz gold buffalo Jan. 30 then gold spot briefly went up and quickly fell down as of yesterday. Could have saved about $75 had I bought yesterday.  I don't sell anyway, I keep it. Edited by livingwater

On the scale of solvent polarity, alcohols are more polar than acetone, and less polar than water. So they will be less effective at removing oily/greasy stuff than acetone or "mineral spirits" (hydrocarbons).
To the best of my knowledge, there is no reaction with coinage metals or their oxides, sulfides or carbonates (tarnish, verdigris).

Continuing the topic, how can such finger marks be removed?  |

Slerk, fingerprints such as the ones on your coin cannot be removed. Acidic oils in the fingerprints have chemically reacted with the surface metal of the coin, and they are now permanent. If I am incorrect and you find a way to remove them without damaging the coin, please let me know. I have a 1909 VDB Lincoln Wheat cent that would benefit from this treatment.

E-Z-est coin dip might work but it will ruin the coin. John1 |
