If you need to clean skin oils or dirt off a treasure coin, the best method is gentle and non-abrasive.
Here's how to clean treasure coins safely:
- Soak: Immerse the coin in warm water with a few drops of non-citrus dish soap (like Blue Dawn) for several minutes.
- Swirl: Gently swirl the coin in the soapy water to loosen any debris.
- Rinse: Thoroughly rinse the coin with clean water to remove all traces of soap.
- Dry: Use a soft, cotton towel to gently and completely dry the coin. Avoid rubbing vigorously, as this can scratch the surface.
Important Considerations:
- Avoid Abrasives: Never use harsh chemicals, abrasive cleaners, or brushes on treasure coins, as these can damage the surface and reduce their value.
- Handle with Care: Always handle coins by their edges to avoid transferring oils from your skin.
- Patina: Be aware that cleaning may remove patina, which is the natural oxidation layer that forms on coins over time. Some collectors value patina, so consider whether cleaning is necessary.
This gentle cleaning method should be sufficient for removing most surface contaminants. Avoid more aggressive cleaning unless you are a professional conservator.
