Cleaning dirty coins can be a fun and satisfying task to undertake. While it’s important to approach it with caution to avoid damaging the coins, there are several methods you can try to restore their shine. Here’s a step-by-step guide on how to clean dirty coins:
1. Gather your supplies: You will need a soft-bristled toothbrush, mild dish soap, warm water, a clean cloth or towel, and a magnifying glass (optional).
2. Identify the type of coin: Before cleaning the coins, determine their material and value. If you suspect the coins may be valuable or collectible, it’s best to consult a professional coin dealer or a numismatist for advice before cleaning.
3. Start by removing loose dirt: Gently rinse the dirty coins under warm water to remove any loose dirt or debris. Avoid using forceful water pressure, as it may cause scratches.
4. Create a cleaning solution: Fill a bowl with warm water and add a few drops of mild dish soap. Mix it gently until the soap dissolves.
5. Soak the coins: Place the coins in the soapy water and let them soak for 5-10 minutes. This will help loosen any stubborn grime or buildup.
6. Brush the coins: Take the soft-bristled toothbrush and gently scrub each coin, focusing on areas with dirt or tarnish. Use light pressure and small circular motions. Avoid brushing too hard to prevent scratching the coin’s surface.
7. Rinse and dry thoroughly: After brushing, rinse the coins under warm water to remove any soap residue. Then, pat them dry using a clean cloth or towel. Ensure they are completely dry before storing or displaying them.
