How can I clean my bottom fill Guardian humidifier?

• You can wash the tank, mist spout, and water tank lid (the lid on the bottom of the blue tank) with a mild dish washing soap and warm water and a bottle brush, rinsing well, and drying.

• In the base of the humidifier, you can soak the ultra-sonic disk, in 100% white vinegar for about 5-10 minutes.

• Then clean gently with the brush provided. If you no longer have your brush, you can use a soft bristle toothbrush.

• Drain any excess vinegar and dry with a soft cloth.

• We do not suggest running anything through the humidifier.
