Introduction
Coins can accumulate dirt, oils, and oxidation over time, making them look dull or grimy. Cleaning them properly helps improve appearance while avoiding damage that could reduce their value.
What You'll Need
Steps
Fill a small bowl with warm water and add a few drops of mild dish soap.
Place the coins in the solution and let them soak for several minutes to loosen dirt.
Gently rub each coin with a soft toothbrush using light pressure.
Rinse the coins thoroughly with clean water to remove soap residue.
Pat the coins dry with a microfiber cloth and allow them to air-dry completely.
Alternative Methods
• Soak coins in plain distilled water for light surface dirt
• Use a baking soda and water paste for heavily tarnished modern coins
• Use olive oil soaking for stubborn grime on non-valuable coins
What NOT to Do
• Do not scrub coins with abrasive pads or steel wool
• Do not use harsh chemicals like bleach or ammonia
• Do not clean rare or collectible coins without professional advice
FAQs
