4. Maintenance and Cleaning
Regular cleaning is essential for optimal performance and hygiene of your humidifier. The Reina humidifier is designed for "Whole Machine Cleaning" to simplify this process.
Daily Maintenance:
- Empty and rinse the water tank daily.
- Wipe down the inside of the tank and the base with a clean cloth.
- Refill with fresh, cool water.
Weekly Cleaning (Whole Machine Cleaning):
- Disconnect Power: Always unplug the humidifier before cleaning.
- Disassemble: Carefully separate the water tank from the base unit. The design allows for easy separation of components for thorough cleaning.
- Clean Water Tank:
- Fill the tank with 1 cup of white vinegar and 1 cup of water. Let it sit for 30 minutes to an hour to loosen mineral deposits.
- Use a soft brush or sponge to scrub the inside of the tank and remove any scale or residue.
- Rinse thoroughly with clean water until the vinegar smell is gone.
- Clean Base Unit:
- Wipe the surface of the base unit with a soft, damp cloth.
- For the ultrasonic transducer (the small disc that produces mist), gently clean with a soft brush or cotton swab dipped in white vinegar to remove mineral buildup. Do not scrub aggressively.
- Rinse the transducer area with a small amount of clean water, being careful not to immerse the entire base unit in water.
- Dry and Reassemble: Allow all parts to air dry completely before reassembling the humidifier.
Important: Do not use harsh chemicals, abrasive cleaners, or metal tools for cleaning, as these can damage the humidifier.
