Using this door hanger is a breeze. Just find a standard door and hang the hanger on it. It's so light that it won't put too much stress on the door. Make sure to place it where guests can easily see the 'Do Not Disturb' message. When it comes to maintenance, a gentle wipe with a soft cloth is enough to keep it clean. Avoid using harsh chemicals as they might damage the vinyl material. Store it in a dry place when not in use to keep it in good condition for a long time.
