Removing Mineral Build Up
Both the cool mist and warm mist humidifiers require removing the mineral buildup. To remove the mineral buildup, pour approximately one cup or 8 ounces of undiluted white vinegar into the base of water holding receptacle.
Allow the vinegar to sit and soak in the humidifier for at least one half hour. Redistribute the vinegar occasionally by gently shaking the holding receptacle. Swish the solution around the container making sure that it coats the entire base. Additionally, use a soft bristled brush to gently scrub the interior of the container. Repeat the scrubbing process a second time on areas that appear to be encrusted with a mineral build up.
Once the half hour has passed, slowly pour the vinegar from the holding receptacle. Rinse it thoroughly with clean water to remove the mineral and vinegar residue. Rinse the container a second time to ensure that you have removed all of the residue.
Disinfecting the Humidifier
Once you have cleaned the humidifier, you should disinfect it. One method of disinfecting is as follows. Fill the holding receptacle or base with clean water, making sure that you know how much water you are using. Next, add one teaspoon of liquid chlorine bleach to every gallon of water that you have in the base.
Allow this solution to sit and soak for at least half an hour. Occasionally, gently swish the solution to coat the base evenly. Once the half hour has passed, pour the bleach solution down the drain, being careful not to spill any. Rinse the base several times until the smell of bleach has dissipated.
Remember when you are cleaning your humidifier to unplug it. Also, avoid commercial cleaners as they are unnecessary. Never allow any vinegar residue to remain in your humidifier.
