To keep your Zippo Lighter in top condition, avoid extreme heat or cold, clean the exterior with a soft cloth and mild soap or cleaning solution, and avoid using abrasive materials or harsh chemicals that may damage the finish. Regularly inspect and replace the flint if necessary. Ensure the lighter is dry before refilling to prevent fuel leakage. Store it in a protective case or pouch when not in use, and keep it away from children and pets. Adjust the flint wheel tension if the flame becomes weak or inconsistent.
