As soon as you see any dirt or stain on the wallet, use a clean damp cloth to clean it. A leather conditioner can also be used to ease out the stain. Never use soap or detergent to clean your leather wallet. In case your wallet gets wet, wipe the surface with a clean, dry cloth and let it dry at room temperature. Don't use a dryer or keep the wallet in sunlight because this will wrinkle the leather. If you see cracks on the surface of your wallet, rub a leather cream or any other natural product specifically designed to moisturize the leather.
