Coin cleaning with ultrasound
Anyone who collects coins knows that they are not only valuable collectibles, but also particularly demanding to maintain. Dust, fingerprints, dirt, and even verdigris can build up on the surfaces and diminish the beauty and value of the coins. Instead of laboriously cleaning with cloths or chemicals, ultrasonic cleaning offers a quick, gentle, and effective alternative.
Why ultrasound for coins?
An ultrasonic device uses high-frequency sound waves that create tiny bubbles in the liquid. When these bubbles collapse, even the finest dirt and deposits are removed – thoroughly, hygienically, and without mechanical interference. Coins thus shine like new again without being damaged by rubbing or polishing.
How to clean coins in an ultrasonic bath
-
Prepare the machine: Fill the tray with distilled water. For heavier soiling, special coin cleaning concentrates can be used.
-
Inserting coins: Place the coins in the collection basket without overlapping them. This will prevent scratches.
-
Start cleaning: Turn on the device and let the coins clean for a few minutes. Important: Do not leave the coins in the ultrasonic bath for too long.
-
Post-processing: Rinse the coins with clear, lime-free water.
-
Drying: Dry the coins carefully in the air or with a soft, lint-free cloth.
Important information on coin cleaning
-
Do not use unsuitable concentrates – these can attack the alloy and reduce its collector value.
-
Avoid polishing: streaks or scratches often cannot be reversed.
-
Remove water stains immediately, otherwise they may remain permanently visible.
-
It is better to clean coins individually to avoid damage caused by friction.
Conclusion
Cleaning coins in an ultrasonic bath is a time-saving and gentle method for restoring collectibles to their former glory. With the right cleaning agent, a short cleaning time, and careful post-treatment, coins retain not only their beauty but also their value.
