Use a penetrating oil like WD-40 to loosen the rust, then let it sit for 10-15 minutes. Carefully use a socket wrench with a spark plug socket, ensuring you turn counterclockwise. If it remains stuck, apply mild heat using a heat gun, ensuring you don't damage surrounding parts. Avoid excessive force to prevent breaking the plug.
