How to Clean a Challenge Coin
To clean a challenge coin, gently wash it with warm water and mild dish soap using a soft cloth or cotton swab. Rinse thoroughly, pat dry, and make sure it is completely air dried before storing or displaying to prevent tarnishing. Avoid abrasive cleaners, harsh chemicals, or scrubbing, which can permanently damage the finish.
Challenge coins carry real weight—not just in your hand, but in what they represent. For first responders, law enforcement officers, and military personnel, challenge coins symbolize service, sacrifice, and belonging. Keeping them in pristine condition is a matter of respect as much as maintenance.
The good news? Cleaning a challenge coin properly takes just a few minutes and a handful of household items. Here's exactly how to do it.
What You'll Need Before You Start
Gather these supplies before cleaning:
Mild dish soap (no harsh detergents)
Warm water
Soft lint-free cloth or microfiber towel
Cotton swabs for detailed areas
Coin storage capsule or soft pouch for after cleaning
Avoid paper towels—they're more abrasive than they look and can leave micro-scratches on polished finishes.
How to Clean Your Challenge Coin: Step-by-Step
Step 1: Rinse with warm water first
Hold the coin under warm (not hot) running water to loosen any surface dust or debris. This simple first step removes loose particles before you touch the coin, reducing the risk of scratching the surface.
Step 2: Apply a small amount of mild dish soap
Place a drop of mild dish soap onto your soft cloth or directly onto the coin. Work gently in small, circular motions across both sides. For coins with raised lettering or detailed engravings, use a cotton swab to carefully clean the recessed areas without applying too much pressure.
Step 4: Rinse thoroughly
Rinse the coin completely under warm water, making sure no soap residue remains. Leftover soap film can dull a coin's shine over time and attract more dirt.
Step 5: Pat dry—never rub
Use a clean, soft cloth to gently pat the coin dry on both sides. Rubbing creates friction that can scratch the surface. Pay special attention to any recessed areas where moisture can collect.
Step 6: Air dry completely before storing
Let the coin sit on a dry cloth for several minutes to ensure it's fully dry. Storing a coin while it's still slightly damp can lead to oxidation, water spots, and long-term tarnishing.
What to Avoid When Cleaning Challenge Coins
Some common cleaning methods can do more harm than good:
Metal polish or silver cleaner: These are too abrasive for most challenge coin finishes
Bleach or ammonia-based cleaners: They strip plating and damage enamel fills
Ultrasonic cleaners: Not safe for coins with soft enamel colouring
Steel wool or rough cloths: These will scratch even hard metal finishes permanently
Never Use a Paper Towel: Despite feeling soft, paper towels have a surprisingly rough, fibrous texture that can leave fine scratches on your coin's finish — making them one of the worst cleaning tools you can use.
Avoid Soaking in Water: Use as little water as possible, and always dry your coins thoroughly with a soft cloth immediately after cleaning.
When in doubt, less is more. Warm water and soap handle the majority of cleaning needs without any risk to the coin's finish.
How to Keep Your Challenge Coin Looking Its Best
Cleaning is only part of the equation. How you store and handle your coin matters just as much.
Handle coins by the edges – The oils on your fingertips transfer easily to metal surfaces and cause tarnishing over time.
Store coins individually – Stacking or storing coins together without padding causes them to rub against each other and scratch.
Use a display case or coin capsule – These protect against dust, moisture, and accidental drops while keeping your coin visible.
Keep coins away from humidity – Bathrooms, basements, and outdoor storage areas accelerate corrosion. A cool, dry environment is ideal.
Avoid direct sunlight – Prolonged UV exposure can fade enamel colours and dull metal finishes over time.
Consistent, simple habits go a long way toward preserving the appearance and integrity of your coin over the years.
Your Coins Deserve the Same Care You Give Your Work
A challenge coin that's earned through service should be preserved with the same dedication. Regular, gentle cleaning—every few months or whenever grime becomes visible—keeps your coins looking sharp for years to come.
