Do not use hard brushes, steel wool or other abrasives on heat element to avoid damage.
REMOVE MINERAL BUILD-UP
The Element Steam Humidifier includes a packet of Vornado Cleaner & Descaler. Consisting of citric acid, this agent is used to loosen and remove mineral build-up on the heat element. It is easy-to-use and safe for all Vornado Steam Humidifiers.
1. Turn off humidifier, unplug and let cool before cleaning. Do not run unit at any time during the cleaning process. Disassemble humidifier as outlined in CLEANING section of the Owner’s Guide.
2. Empty any water in base and silicone boil chamber & reservoir.
3. Combine granules from the cleaning packet and mix with 6 oz. of water in a measuring cup (not included) until completely dissolved. Pour mixture into the silicone boil chamber and reservoir in base. If using more than 6 oz. of water, some will flow into the base. This will not hurt base but it is not needed.
4. Set power head on base and attach (without silicone heat element cover attached). This will submerge heat element directly into the mixture. Soak for 30 minutes to an hour or longer depending on amount of build-up. You may scrub the heat element with a soft bristle brush as particles begin to loosen. Avoid hard brushes or steel wool as they can damage the heat element.
5. Once clean, thoroughly rinse base, silicone parts and heat element with cool tap water to ensure all residue is gone before using.
NOTE: Undiluted white vinegar may also be used for cleaning the heat element, however, citric acid is recommended.
