Unplug your humidifier from the outlet. This is an important safety measure to take before you start cleaning it.
Remove the water tank from the humidifier and empty it. Dry it out and refill before putting it back in the humidifier. This should be done every day.
Empty the humidifier and scrub it out at least once every three days or when you notice a buildup of residue. Scrub the humidifier thoroughly using a scrub brush.
Rinse out the humidifier with 3 percent hydrogen peroxide. This is a cleaning agent that is nontoxic. Again, scrub out the tank.
Use clean water to rinse the tank several times. Then, dry it out, refill and put back into the humidifier.
