Never clean coins with abrasives or acids. including kitchen cleaners

Although abrasive products are often advertised on TV or in stores as effective for cleaning coins, this is not the case. Acidic cleaners and kitchen cleaners remove some of the material of the coin’s surface during the process of cleaning it. Although this will make the coin look cleaner and improve its shine, the coin will be damaged and its value diminished.

Similarly, you should never scrub or scrape coins in order to remove tarnish or blackness. Products like steel wool or wire brushes will irreversibly damage your coins and remove their value.
