Perhaps not wire brushes, but old toothbrushes 'n water are often used to clean coins recovered from ground burial.

Just a dip in Aqua Regia is all I need.

I agree, why don't you go take a dip.  Quote:
As for brushes, toothbrushes are usually nylon, which cannot scratch metal in and of itself. But if there is dirt or grit there the toothbrush can drag it around and it can cause scratches. |

the "salts" they show look a lot like copper salts. guessing that after turning everything as bright as the sun with the brass brush that they help re-patina? Quote:
the results, if you can believe them, do not look that bad. add me to that list as well.  hmmm.... add blue food coloring to some salt (3 cents), combine with a dollar store brush, sell for $28... net $26.97... this guy is on to something  |

The "blue salt" is to be dissolved in solution and used to patina the wire brushed coins. Salt and blue food coloring wouldn't do that. But what about copper sulphate? Has a nice blue color, dissolves easily in water, and provides sulphate ions in solution to react with the copper of the coin darkening it.

Hello. Collector of coins for many many years, and the topic of cleaning has recently come up for debate. I get the entire how to be safe on how not to be destructive to the coin (which I will probably use toothbrush all the time), but what about safety to yourself? in cleaning coins, what hand/fingers protection should be used? I look forward to replies. Thank you.

WARNING! ACHTUNG! :- Be very careful with copper sulfate crystals. Highly water soluble. Extremely poisonous!
Blue copper sulfate solution is also extremely poisonous. Waterproof gloves absolutely essential, and must be disposed of after use.

So now I'm assuming your talking about detector finds . No matter what the metal composition is , just rinse it in distilled water ,no rubbing or scrubbing . If need be carefully use a tooth pick or Q-tip to get the soil out of and around devices . This method does not require special gloves or masks nor does it cost you any $ .  |

There should be a law.... There is: supply and demand. The tsunami of cleaned shrapnel on ebay can be seen in declining prices realized and the endless parade of ebay's relisted / overpriced / cleaned garbage that never seems to go away. In that sea of despair, however, real coins apparently still swim. |
