To clean platinum coins, use mild soap and water.
While it's generally advisable to avoid cleaning coins, especially valuable ones, if you must clean a platinum coin, do so with extreme care. Improper cleaning can damage the coin's surface and diminish its value.
Gentle Cleaning Steps:
- Prepare a Solution: Mix a small amount of mild dish soap (like Dawn) with lukewarm distilled water. Avoid using abrasive cleaners or chemicals.
- Soak the Coin: Gently submerge the platinum coin in the soapy water for a few minutes.
- Rinse Thoroughly: Remove the coin and rinse it thoroughly under lukewarm distilled water. Make sure to remove all traces of soap.
- Dry Carefully: Pat the coin dry with a very soft, lint-free cloth. Do not rub the coin, as this can cause scratches. Microfiber cloths are a good option. Air drying is also acceptable.
Why You Should Be Cautious:
- Platinum's Softness: Platinum, while durable, is still a relatively soft metal. Abrasive cleaning methods can easily scratch its surface, resulting in a decrease in value.
- Toning & Patina: Some collectors value the natural toning or patina that develops on coins over time. Cleaning removes this patina, which can make the coin less desirable to collectors.
- Potential for Damage: Harsh chemicals can react with the metal and cause discoloration or other damage.
Alternatives to Cleaning:
- Prevention: The best way to keep platinum coins clean is to handle them with care and store them properly in protective holders or albums.
- Professional Cleaning: If the coin is valuable or heavily soiled, consider consulting a professional coin conservator or numismatist. They have the expertise and specialized tools to clean coins safely and effectively.
In summary, if cleaning is necessary, use the gentlest method possible. Always prioritize preserving the coin's original surface and avoid abrasive techniques. If in doubt, seek professional assistance.
