Care and Maintenance Guide: Cleaning: Use saddle soap for overall cleaning. Nursing and Maintenance: Mink Oil: Similar in composition to leather, ideal for daily care. Neatsfoot Oil: Can darken the color of the leather, deepening the belt's hue. Note that any oil applied will cause the leather to change color. Application Method: Vegetable - tanned leather belts are highly absorbent. Use a cotton cloth to gently apply a small amount of oil in a circular motion on the belt surface, ensuring an even spread. Keep the working environment clean and dust - free. Then, let it dry naturally for the oil to be absorbed and volatilized.
