Numismatic Rust Removal, also known as “How To Clean Rust Coins,” refers to the process of removing rust and corrosion from coins. Rust, a common problem for coins, forms when iron in the coin reacts with oxygen and moisture in the environment. Rust can damage coins, reducing their value and aesthetic appeal. Removing rust is essential for preserving and restoring coins.
Cleaning rust from coins requires careful techniques to avoid further damage. Common methods include using a soft cloth or brush with a mild cleaning solution or a specialized numismatic rust remover. Electrolytic rust removal, a more advanced technique, uses an electric current to dissolve rust. The choice of method depends on the coin’s age, condition, and metal composition.
