Removing dirt, greenery, oxides from old copper coins while preserving the original patina with Extra Virgin olive oil. The principle is shown, the degree of intensity can be varied at your discretion. Light cleaning will preserve the patina, but if you put the coin in oil for a longer time, it can be "cleaned" until it turns red (virgin oil contains acids). At the same time, the oil preserves the coin. If you coat (wipe) a coin with a thin layer of oil and allow it to dry, a microscopic protective film will form. It can be dried immediately on a hotplate (up to 100 degrees C), but there is a risk of "overcooking" the coin, then the color will change. It is better to put it on some kind of heat source of 50 degrees C and leave it for several days.
