When you're not using the mirror, simply close the lid to protect it. As for maintenance, clean the mirror with a soft, dry cloth regularly to keep it clear. Avoid using harsh chemicals as they might damage the mirror's surface. Also, make sure to check the mounting periodically to ensure it's secure and stable.
