Verdi-Chem Coin Conservation Fluid 30ml
From the US importer: At last a modern alternative to using oil and harsh solvents on coins! Coin conservationists have used oil on coins for hundreds of years. Coin conservationists have used solvents for decades. However, oils contain trace amounts of impurities that can actually act to damage a coin’s surface over time and solvents may harm or strip the patina. Also, oils are difficult to remove, slowly degrade, allow moisture to get to the surface and may have negative health effects. Oils are ‘old school’ and have primarily been used because there was no other choice. It’s time to move into the 21st century with a modern-day, alternative that utilizes the latest advances in chemical technology and coin conservation science.
