Things You'll Need
Humidifiers work to put moisture into the air, but sometimes an unpleasant, musty odor develops in a humidifier that leaves the room smelling uninviting. It's important to clean the humidifier with a natural deodorizing agent, because the use of chemical cleaners could produce harmful vapors that you do not want your family to breathe.
Fill the humidifier with water as you normally would, and pour in 4 tsp. lemon juice. Bottled lemon juice works well, but if you use fresh lemon juice, strain it well so no pulp is left.
Turn on the humidifier and let it run for one hour. The lemon juice will deodorize the humidifier and give the room a fresh, citrus scent.
Discard the water and lemon juice mixture, rinse the humidifier water tank, and wipe it with a clean rag.
Repeat every one or two weeks or as needed to keep the humidifier smelling clean and fresh.
