Removing dirt
ОглавлениеDirt is an abrasive that will scratch the heck out of a coin if you’re not careful. Never rub, never scrub, and never polish; always use a light touch. Follow these steps to remove dirt:
1 Use an artist’s paintbrush to lightly whisk off any surface dirt.Be careful not to exert any pressure.
2 Rinse the coin under warm water to remove additional surface dirt.Don’t rub the coin between your thumb and forefinger.
3 After rinsing the coin, pat it dry with a soft towel.Avoid pressure and any rubbing motions.
Don’t use paper towels to dry a coin; the wood fibers in the paper may leave hairline scratches on fine surfaces. Use a 100 percent cotton cloth.
If you have really crusty and dirty coins, soak them in olive oil for a couple of days; then try picking the dirt off with a toothpick. Again, be careful not to exert too much pressure; the toothpick may scratch your coin.
