How to Clean a Dehumidifier Water Tank

A dehumidifier can prove an invaluable appliance, especially in climates that are prone to excessive humidity. Humidity, which is a measure of the amount of moisture in the atmosphere, can cause the air to feel oppressive, intensifying heat and possibly aggravating allergies. In some instances, high humidity may lead to the formation of mold or mildew and damage sensitive home or office furnishings. As its name suggests, a dehumidifier reduces the level of moisture in the air. Clean the water tank or reservoir one to two times a month to keep it running effectively.

  1. Unplug the dehumidifying unit from its power source. Do not allow the unit to run if the water tank or any other component has been removed.

  2. Remove the water tank or reservoir from the main body of the dehumidifier. The exact method for removing the tank will depend on which type of dehumidifier you own. For most units, the water tank or reservoir will simply slide out of place as you pull on it.

  3. Dampen a clean, lint-free cloth in some water and thoroughly wipe down the entire surface of the water tank. Clean the inside of the tank as well as the outside. Do not use detergents to clean the reservoir. Harsh chemicals may find their way into the inner workings of the dehumidifier and damage its electrical components.

  4. Continue wiping the water tank until you are satisfied that you've removed all dirt, mineral deposits and any signs of mold or mildew.

  5. Allow the tank to air-dry completely and slide it back into place within the dehumidifying unit. After you have replaced the tank, plug the unit back into its power source.
