Many regions have hard water with high concentrations of minerals. When water evaporates from The Care Free® Humidifier, minerals may be left behind. These minerals can form a hard white scale which can be removed by following the cleaning instructions. The frequency of cleaning due to mineral build up can vary depending upon the quality of water you may have.

• Turn the humidifier ‘OFF’ and Unplug the unit.
  
  
• Lift the main housing and remove the water dispersion tray and the PermaWick™ Filters.
  
  The motor is attached to the main housing. Do not place the motor near water. Do not use a wet towel on the motor or motor housing as electrical shock may occur.
  
  
• The PermaWick™ Filter should be cleaned in a vinegar and water solution to remove any mineral buildup. Place in a solution of one (1) gallon of water and eight (8) ounces of undiluted white vinegar. Allow the filter to soak for 20 minutes.
  
  
• After soaking, rinse it several times with clean water. Place the PermaWick™ Filter
  in a location where it can drip dry while you clean the other parts of your humidifier.
  
  
• Remove the water tank from the base and empty any water that is left in the tank. Soak the base in a mixture of one (1) gallon of water and eight (8) ounces of vinegar for 20 minutes.
  
  
• After soaking, wipe the base with a soft cloth or sponge to remove any mineral build up. Rinse with clean water several times. If you are planning on storing the humidifier, be sure the base is completely dry.
  
  
• Fill the water tank with one (1) gallon of water and eight ounces of undiluted white vinegar. Replace the tank cap and shake the tank vigorously until all interior surfaces of the tank have been exposed to the water/vinegar mixture.
  
  
• Empty the tank of the water/vinegar mixture. Rinse it several times with clean water and then replace the tank cap. If you are planning on storing the humidifier, dry it inside and out, leaving the cap off to allow the tank to completely dry. Continue to clean the other parts of your humidifier.
  
  
• Remove the water diffuser cap and sponge. Rinse the sponge in clean water to remove
  any debris. If the sponge contains hard water residue, soak it in a mixture of
  one (1) gallon of water and eight (8) ounces of vinegar for 20 minutes. Rinse well and reinstall sponge and diffuser cap in unit.
  
  Do not expose motor or other electrical components to water.
  
  
• Wipe the surfaces of the main housing with a soft cloth.
  
  
• Once all the parts are clean, reassemble the humidifier.
  
  If you are storing the humidifier, make sure the parts are completely dry, reassemble, and store in a dry location.
