As for maintenance, wipe the bunk bed with a clean, dry cloth regularly to keep it looking good. Avoid using harsh chemicals that could damage the wood finish. If there are any scratches or damages, you can touch them up with a suitable wood repair kit. Also, check the tightness of the screws every few months to ensure the bed remains sturdy.
