I'm having a problem with what I can only assume are mineral deposits. I usually run my warm mist humidifier in the winter and clean the heating elements about once per month with vinegar. I've never really had any issues with mineral deposits.
Yesterday I cleaned the heating elements with vinegar and ran the humidifier for maybe four to eight hours. I noticed it wasn't producing much steam despite being set to high. When I looked at the heating element it looked as if it was covered in wet sugar. I assume those are mineral deposits, except that I've never seen mineral deposits that look like that.
Any ideas as to what this problem is? I don't know if it's not producing steam because there are too many minerals or because there aren't enough. I don't know what the wet sugar like stuff is covering the heating element. Is there something I could add to the water in the humidifier tank? Interestingly, I have a 20 y/o vaporizer that says to add baking soda if the mineral content is low and a four y/o vaporizer that says to add salt if the mineral content is low. It seems like salt should be added if the mineral content is high since salt pellets are added to a water conditioner if the mineral content is high.
I do have hard water and use a water conditioner. I'm not the one who is in charge of taking care of the water conditioner so I don't know if the salt pellets were added this month. It would be a few days before I could find out.
