Yep. That's what I have been told. Equal quantities of vinegar and lemon juice. Will that work as acetone to dip and have my precious proof silver coin cleaned from my dad's unforgiving fingerprint? If not, do you think it might be possible to find acetone at a paint shop, as it is a solvent? Or perhaps if some day my dad becomes really-really famous, might the fingerprint add value to the coin? This is the coin by the way... https://en.numista.com/catalogue/pieces307039.html |

Lemon juice and vinegar
sometimes helps in cleaning ancient silver coins recovered from ground burial. Can still be risky, but that is what a museum curator is faced with, and thus experience and judgement needed.
But
an excellent way of destroying nice modern silver coins with attractive luster.
Acetone good for dissolving and removing removing organic substances without any further harm to the coin,
but is rather useless in removing inorganic substances, such as oxides and sulfides.

If you can post a picture, you might get better advice. Acetone can do wonders on silver proofs depending on what is on them. http://goccf.com/t/397521 |

Fingerprints are forever unless they are removed very quickly. There is no way to remove them without damaging the coin. John1  |

There is no way to remove them without damaging the coin.  Do not use vinegar and lemon on your coin unless you want to ruin it. Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

And what about a dip in alcohol? I heard it might work as a softer acetone, and it won't damage the coin. Should I try?

The fingerprint is corrosion with the shape of the fingerrint.
You have received three warnings that your procedure will not work (neither acetone nor alcohol can remove corrosion because they are incapable of chemical reaction with a metallic oxide or sulfate or carbonate; acid in lemon juice or vinegar might, but may also remove the luster).
Proceed at your own risk.

Well, actually the coin has some sort of dots, or clouds! That's the word. Very tiny clouds on a section of the reverse, but they're not in the shape of a fingerprint exactly. I wonder if it could be a fingerprint or something else. I will dip it in alcohol for tonight and report later about the results. Thank you for your advice!
