Humidifiers add moisture to the air during long dry winters. Vicks humidifiers go a step further and release medication into the air to help ease sore throats and coughs. Unlike the traditional humidifier, these come with a separate tray to hold the medication. You need to clean a Vicks Warm Mist humidifier weekly to avoid mineral scale build-up and to prevent bacteria from growing in the water tank. This will prolong the life of your humidifier and ensure the quality of the air.

Step 1

Take the water tank off the unit and empty any excess water. Fill with 1 teaspoon of bleach mixed with 1 gallon of water and let soak for 20 minutes, shaking every few minutes.

Step 2

Remove the medicine cup from the top of the cooling chamber then carefully lift the cooling chamber from the base. Take the removable water tray off the base.

Step 3

Rinse the water tray then soak it and the heating chamber in white vinegar for 20 minutes. This will remove any mineral scale buildup.

Step 4

Dump the vinegar out of the heating chamber and water tray. Wipe with a cloth dampened with vinegar.

Step 5

Dump out the water tank and rinse until all traces of bleach are removed. Wipe dry with a clean cloth.

Step 6

Wash the water tray, medicine cup and cooling chamber on the top shelf of your dishwasher to disinfect.

Step 7

Wipe down all surfaces with a cloth soaked in diluted bleach. Wipe clean with a cloth dampened only with water to remove traces of bleach.
